Arnold & Son Luna Magna Platinum Limited Edition

This brand new Luna Magna watch in Platinum boasts an aventurine crystal sky dial featuring a large three-dimensional moon composed of blue aventurine and grey marble.

Featuring a fully polished 950 platinum case, this celestial inspired timepiece also features a white mother-of-pearl hour and minute sub-dial in a satin-brushed ring.

Arnold & Son Luna Magna Platinum Limited Edition

The Arnold & Son Luna Magna Platinum watch is a limited series of only twenty-eight pieces. Set in aventurine crystal, the metallic crystals bring the dial to life with their brilliance. Half of the 12 mm three-dimensional moon is made of grey marble and the other half of aventurine crystal, reflecting the moon’s dual nature.

Arnold & Son Luna Magna Platinum Limited Edition

The hours and minutes are displayed on the graduated dial with twelve Roman numerals bearing the Arnold & Son signature. This eccentric disc owes its luminosity to the slightly iridescent white mother-of-pearl.

Luna Magna Platinum is based on the A&S1021 calibre, which has been fully developed and then assembled and adjusted in Switzerland. Designed around the lunar globe, the movement is hand-wound and features a 90-hour power reserve and regulating mechanism set at 3 Hz. On the back is a secondary display, with clearly legible lunations for fine adjustments.

Arnold & Son Luna Magna Platinum Limited Edition

The celestial mechanism also owes its sophisticated design to the fidelity in its astronomical accuracy. The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds.

Arnold & Son have succeeded in approximating this cycle such that, if the watch was never stopped, it would take 122 years for the moon-phase display to accumulate a day’s discrepancy from the correct phase. And the correction is easy, since Luna Magna Platinum’s lunar function is accessible directly from the crown.

Arnold & Son Globetrotter Steel

After unveiling the limited edition Globetrotter Gold, Swiss luxury watch brand Arnold & Son is offering new steel versions of its world time wristwatch. The Globetrotter Steel preserves the Earth’s half-globe and sapphire crystal ring, which together make it possible to read the time north of the equator.

Two new stainless steel models are available. The first version has a tonal blue dial, lacquered, with sunburst decoration, in an exclusive series of only 88 pieces. The other has a silvery white dial, also lacquered and with sunburst decoration, with no limit on the number of pieces.

Arnold & Son Globetrotter Steel

The case forms a continuous line from the strap to the sapphire crystal dome suspended above the dial. This large transparent hemisphere follows the line of the steel arch bridge that sets the Globetrotter collection apart from all other timepieces.

Arnold & Son Globetrotter Steel

This arch is open-worked with a satin finish on all its flat surfaces, chamfered and polished by hand. The slender chords rest on two feet fixed with screws, like a stylised bridge spanning two banks. Here it reaches across half of the world, the most densely inhabited part of the earth: the northern hemisphere.

Arnold & Son Globetrotter Steel watch with blue dial

At 45mm, the Globetrotter Steel has a large case. The hemisphere was the guiding principle for the design, requiring a certain amount of space. Everything resting above the equator, including America, Eurasia and Africa, is all visible in a wealth of detail. The model is a one-of-a-kind sculpture, the continents first rhodium-plated and polished.

Arnold & Son Globetrotter Steel

In contrast, mountain ranges are rendered matt. The oceans are hand-painted with numerous layers of lacquer in blue pigments, enriched with mother-of-pearl powder which imparts exceptional depth and shine. In a lighter tone enriched with Super-LumiNova, the shorelines stand out at night, further accentuating the textured elements of this miniature showcase of manual craftsmanship.

Arnold & Son Globetrotter Steel

Arnold & Son is also offering the southern hemisphere variant and can customise the world map of Globetrotter collection pieces to special order.

Arnold & Son Globetrotter Steel watch with opaline dial

The Globetrotter Steel is equipped with the Maison’s A&S6022 self-winding calibre. Like all Arnold & Son movements, it has been fully developed, manufactured, decorated, assembled, adjusted and fitted at its factory in La Chaux-de-Fonds. The oscillating weight with a Clous de Paris guilloché pattern is skeletonized and NAC coated, bringing its hue closer to that of the movement.

Arnold & Son Globetrotter Steel

The A&S6022 calibre is decorated according to traditional fine watchmaking motifs: pearlized main plate, sunburst Côtes de Genève bridges, satin-finished wheels, and chamfered and polished screws. The specific finish used for this model is its very special NAC treatment. This type of plating uses precious metals which are close to platinum, resulting in a particularly high-quality anthracite finish that perfectly matches the grey case of the Globetrotter Steel.

Arnold & Son Luna Magna Ultimate I Limited Edition

After presenting the Luna Magna, Swiss luxury watch brand Arnold & Son is presenting a series of high-end jewellery interpretations of its three-dimensional moon model.

In addition to the technical feat of placing a mechanical star measuring 12mm inside a watch, the Luna Magna Ultimate I watch highlights paved and invisibly-set precious stones. The case, measuring 44mm in diameter, is made of white gold and set with 7.62 carats of the highest quality diamonds. These include 20 baguette-cut diamonds on the case’s lugs, cut one by one to fit the unique shape of each mount.

Arnold & Son Luna Magna Ultimate I Limited Edition

A fine ring resembling the ring around Saturn constitutes the bezel, orbiting the Luna Magna Ultimate I case. It contains 112 baguette-cut diamonds totalling 5.90 carats. Light can enter freely, just as it would an open prism, thanks to the dual-row invisible setting which allows for radiance beyond compare.

Hundreds of pure ruthenium crystals make up the sparkling blue façade of the dial. This extremely hard and precious metal belongs to the platinum group. Within the circle of blue radiance lies a dial in the conventional sense, featuring twelve Roman numeral markings, the Arnold & Son signature and the hands. This off-centre subdial owes its delicate colour to white opal, and its finesse befits a piece of the finest jewellery such as the Luna Magna Ultimate I.

Arnold & Son Luna Magna Ultimate I Limited Edition

Beneath the timepiece, the three-dimensional moon is the standout feature of the Luna Magna watches. Gem-setting of the utmost intricacy coats the entire white gold sphere. It is divided into 161 brilliant-cut diamonds for daytime and as many blue sapphires for night-time. The line between the two colours is a ripple of blue and white along the outline of the stones.

Arnold & Son Luna Magna Ultimate I Limited Edition

The Luna Magna Ultimate I watch is equipped with the A&S1021 calibre, which is entirely developed, manufactured, assembled and adjusted in-house at Arnold & Son.

This hand-wound calibre, designed around the lunar globe, has a power reserve of 90 hours and a regulating organ at a frequency of 3 Hz. As for the case back, the movement provides a second display for the lunar phase, featuring easy-to-read graduations for utmost precision when correcting the lunar globe.

Arnold & Son Luna Magna Ultimate I Limited Edition

The celestial mechanism of the Luna Magna Ultimate I watch is extremely accurate. The length of a full moon cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. Arnold & Son has produced a likeness such that it would take 122 years for the movement to accrue a one-day interval between the watch display and the true celestial cycle. Nevertheless, this error is easy to correct given that the lunar function on the Luna Magna Ultimate I is directly accessible from the crown.

Arnold & Son Globetrotter Gold Limited Edition

With the limited edition Globetrotter Gold watch, Arnold & Son pays tribute to John Arnold’s marine chronometers, which were embarked on English naval ships in the 18th century.

The Globetrotter Gold watch measures 45mm in diameter. In its centre, the dome depicting the Northern Hemisphere is held from side to side by an immense open-worked bridge carved in red gold. This arch is the visual signature of the Globetrotter, and houses in its centre a functional ruby holding the axis of universal time.

Arnold & Son Globetrotter Gold Limited Edition

With its Globetrotter Gold, Arnold & Son has chosen to refine the aesthetics of this major piece in a way which affirms its elegance and modernity. The appliqué indexes on two planes are faceted in red gold and painted in Super-LumiNova.

The bottom part of the dial which surrounds the map of the world has a subtle sunlit finish in shades of blue, and the ring showing universal time is in transparent sapphire. Local times are therefore read by the red hands pointing to the gold indexes, while world times are identified by visualising an imaginary longitude from the ruby in the central bridge to the24-hour sapphire ring.

Arnold & Son Globetrotter Gold Limited Edition

The architecture of the Globetrotter Gold crossways bridge is remarkable. Classy and svelte, the bridge is formed of one central piece in solid gold, with openwork taken to the extreme.

The flat parts of the arch are polished, its sides are satin-finished and the long surfaces of its chamfers bevelled. These types of finishes and the level of quality achieved are those commonly applied to the components of Arnold & Son calibres. However, the dimensions of this bridge are considerably larger than they would be within a movement, and thus demanded exceptional care and precision.

Arnold & Son Globetrotter Gold Limited Edition

At 45 mm, the case of the Globetrotter Gold is vast. The hemisphere was the guideline to its design and its surface area requires a certain amount of space. Above the equator are North America, Eurasia and part of Africa. In reality, the continents form a single rhodium-plated, polished sculpture. In contrast, the Atlas, Hoggar, Himalayan, Rocky, Ural and Alps mountain ranges are given a matt finish.

Arnold & Son Globetrotter Gold Limited Edition

The oceans are hand painted with several coats of blue-pigmented lacquer enriched with pearlescent powder to bestow exceptional depth and shine. The coastlines are lighter on the blue colour scale with added Super-LumiNova, so that they stand out at night and further accentuate the relief of this small piece of manual craftsmanship.

Arnold & Son Globetrotter Gold Limited Edition
The Globetrotter Gold is assembled on the Maison’s automatic calibre A&S6022. Like all Arnold &Son movements, it has been entirely developed, produced, decorated, assembled, adjusted and fitted at their plant in La Chaux-de-Fonds. Its oscillating weight is 22-carat gold, skeletonised and features the Clou de Paris guilloché pattern.

Arnold & Son Globetrotter Gold Limited Edition

The A&S6022 calibre is decorated with the traditional fine watchmaking motifs: stippled mainplate, radiant Côtes de Genève bridges, satin-finished wheels and bevelled, polished screws. Its specific finishes are also NAC-treated. This type of plating uses precious metals close to platinum to produce a particularly high-quality anthracite result that perfectly matches the red gold case of the Globetrotter Gold.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix

Arnold & Son presents five versions of the Ultrathin Tourbillon Dragon & Phoenix, each released as an edition of five pieces, with dials made from rarely used varieties of hardstone. Their structure, colour and richness serve as a backdrop for the two legendary creatures as they dance around their prized pearl.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix

Off-centred dials can be found on several models from the Arnold & Son collections. This arrangement is both the historical heritage of the marine chronometers created by John Arnold in the 18th century and a consequence of the mechanical structure of Arnold & Son’s manufacture calibres. Arnold & Son has produced a series of 25 pieces, based on its Ultrathin Tourbillon model, that pair figures from Chinese mythology with the best Swiss expertise.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix

Arnold & Son references the myth of the Dragon and the Phoenix. The two beasts are depicted by two expressive, precious finely worked miniature sculptures curled up on either side of the dial. Complete with scales, feathers, spurs, teeth, beak and mane, they are entirely crafted from solid rose gold and engraved by hand.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix

 

In the dragon’s claws is the pearl, made from mother-of-pearl. The level of detail is extraordinary, all the more so as these two animals are only around 2 cm long. In the background, Arnold & Son introduces colour and substance: the stone.

Each of the five Ultrathin Tourbillon Dragon & Phoenix models features a dial made from a different hardstone. Bronzite, Eudialyte, Marcassite, Pietersite and Verdite are coloured minerals with deep surface effects, but are little known and rarely used in watchmaking. Arnold & Son chose these varieties of hardstone for their evocative properties.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Bronzite: Reference 1UTAR.Z01A
Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Bronzite: Reference 1UTAR.Z01A

In Bronzite, pearlescent, red and black inclusions stand out against predominant beige tones. Black and grey Marcassite is scattered with outgrowths like stones emerging from a flat landscape.

 Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Eudialyte: Reference 1UTAR.Z02A

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Eudialyte: Reference 1UTAR.Z02A

The deep blue grey of Pietersite is crossed by expansive iridescent clouds. Verdite, meanwhile, reveals a bright, shifting green. Lastly, intense Eudialyte contains gradients of purple opposing mottled white veins.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Marcassite: Reference 1UTAR.Z03A
Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Marcassite: Reference 1UTAR.Z03A

Each of these versions comes with a large-scaled alligator skin strap that matches the dial, paired with 18-carat gold thread topstitching. The strap attaches to a 5N red gold case measuring 42 mm in diameter and 8.60 mm thick.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Pietersite: Reference 1UTAR.Z04A
Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Pietersite: Reference 1UTAR.Z04A

This thinness is all the more remarkable as the Ultrathin Tourbillon Dragon & Phoenix models incorporate a tourbillon calibre. It simultaneously offers accurate timekeeping, a refined skeletonised structure, mechanical nobility and, for good measure, a symmetrical architecture.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Verdite: Reference 1UTAR.Z05A
Arnold & Son Ultrathin Tourbillon Dragon & Phoenix Verdite: Reference 1UTAR.Z05A

The symmetry of the pieces even extends to the domed sections: the skeletonised tourbillon bridge slightly protrudes from the dial, level with the off-centred dial, which is also domed. Meanwhile the mythical creatures carved from gold balance out the design horizontally. The precise proportions, the dynamics and the composition are the product of a keen aesthetic and mechanical sense.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix case back view with A&S8200 calibre

The watch is equipped with A&S8200 calibre. Measuring 2.97 mm thick, it is one of the thinnest to be regulated by a tourbillon. Like all the movements used by Arnold & Son, the A&S8200 calibre was entirely developed, produced, decorated, assembled, adjusted and cased up within the walls of the brand’s manufacture in La Chaux-de-Fonds.

Arnold & Son Ultrathin Tourbillon Dragon & Phoenix with A&S8200 calibre

This calibre is based on a large barrel with an oscillation frequency of 3 Hz, giving a 90-hour power reserve that is extremely rare for a tourbillon, especially given its thinness. The structure is refined further still by the skeletonised tourbillon bridge and hand engraving on the rear tourbillon bridge. As the light passes through the Ultrathin Tourbillon Dragon & Phoenix, it illuminates the mythological scene and brings the mechanical lacework into the mineral landscape.

Arnold & Son Luna Magna Limited Edition

Unveiled at Watches and Wonders 2021, Luna Magna features Arnold & Son’s first three-dimensional moon. With this original timepiece, the Swiss watchmaker with English roots aims to make a lasting impression by presenting the largest moon ever created in relief for a wristwatch.

Beneath an off-centred dial at 12 o’clock, which constitutes one of the house’s aesthetic signatures, Arnold & Son has placed a rotating sphere that accurately represents the appearance of the quarters of the moon against a starry backdrop that is more dazzling than a midsummer night sky.

Arnold & Son Luna Magna Limited Edition

Presented in a 44 mm red-gold case, Arnold & Son has recreated one of its distinctive designs. The off-centred hours and minutes dial at 12 o’clock frees up substantial space for displaying complications, such as this spherical moon measuring 12 mm in diameter. Its size is not its only distinctive feature.

Arnold & Son Luna Magna Limited Edition

Half of the moon is made of marble to represent the illuminated part of the Earth’s satellite, while the other half is made of aventurine glass to depict the darker side. Neither material has ever been used in a three-dimensional design such as this. Changing from dazzling white to a deep, starry blue, the Luna Magna’s quarters have been delicately depicted to replicate the appearance of the lunar disc.

The large moon emerges from the main plate of the A&S1021 calibre without upsetting the overall balance of the timepiece. Arnold & Son has drawn on its remarkable creativity to make Luna Magna a well-proportioned watch that showcases the incredible volume of its moon.

Arnold & Son Luna Magna Limited Edition

The lunar globe thus appears halfway up the movement, perfectly positioned between the top and bottom. The upper part is encased in a glass box. This technique has been repeated on the case-back side, where the sapphire crystal rests on the wrist.

By placing most of the volume in these sapphire crystals, the Luna Magna’s case has a total height of 15.9 mm. Lastly, to bring the overall piece together, the deeply tapered lugs extend the curvature of the sapphire crystal to meet the natural curve of the wrist.

Arnold & Son Luna Magna Limited Edition

Arnold & Son has an ancient, long-standing relationship with the phases of the moon. Guided by the life of John Arnold and the mark he made in the Royal Navy during the 18th century, the house has frequently endeavoured to depict the age of this satellite as accurately and as beautifully as possible.

By completely reinventing the way the Earth’s satellite is depicted, Luna Magna elevates itself by pushing the boundaries of this astronomical and poetic watchmaking exercise.

Arnold & Son Luna Magna Limited Edition

Luna Magna is driven by the A&S1021 calibre, which has been fully developed, manufactured, assembled and adjusted in the Manufacture. This new hand-wound calibre, which has been designed with the lunar globe in mind, features a 90-hour power reserve and a regulating organ oscillating at a frequency of 3 Hz. The movement also includes a secondary display detailing the age of the moon on the case-back side. Its clearly readable markings are designed for high-precision adjustments.

Arnold & Son Luna Magna Limited Edition watch with 3d moonphase

The sophisticated celestial mechanics are also based on precise astronomical reality. In fact, the duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. Arnold & Son has managed to replicate it in such a way that it will take 122 years for the movement’s display to deviate from the correct celestial reading by one day.

The correction required at this time will be easy to dispense, as the Luna Magna’s moon-phase function can be accessed directly by the crown. This practical feature has been made possible by Arnold & Son’s total mastery of the watchmaking process.

Arnold & Son Perpetual Moon “Year of the Ox” Limited Edition

In honour of the traditional Chinese zodiacal calendar’s New Year, Swiss luxury watch brand Arnold & Son has produced an eight-piece limited series of its high-precision moon-phases model decorated with a buffalo. The year of the Metal Buffalo begins on 12 February 2021 and symbolises appeasement, dialogue and soil fertility. It is thus a powerful and docile animal that is represented on the dial of the Perpetual Moon “Year of the Ox”.

Arnold & Son have installed their large moon in the night-sky that forms the dial of this exceptional time-piece. In a large aperture, a disc turns to show us the age of the heavenly body, the appearance of its crescent and its light. This moon is crafted in mother-of-pearl, its shadows are hand-painted and it is coated with Super-LumiNova.

Arnold & Son Perpetual Moon “Year of the Ox” Limited Edition

In the daylight, it is almost white. In the dark, it lights up from within and takes on a new aspect, with details emerging. Further along on this disc, the constellation has been created using the same methods.

Arnold & Son continue to make the most of the infinitely varying textures nature has to offer. After obsidian and aventurine quartz, it is specular hematite that has been selected for making the dial of this Perpetual Moon. This variety of hematite is in laminated form, with layers that are naturally smooth and shiny.

Arnold & Son Perpetual Moon “Year of the Ox” Limited Edition

As with all hematites, due to its iron composition there are silvery flakes in its totally black mass. These glittering specks have also been incorporated into the double-faced alligator-skin strap, the outer face of which is black, flake-speckled and embellished with stitching in veritable platinum (Pt950) thread.

But the unique and exclusive signature of this limited series is the buffalo with immense horns standing, imposingly, at 6 o’clock. It is a miniature gold sculpture featuring the animal in a majestic posture. In the background is a scenery of multi-storey pagodas, hand-painted with gold powder.

Their windows have also been painted with Super-LumiNova. Thus at night-time, these temples are lit up from the interior and the Perpetual Moon takes on an inhabited aspect.

Arnold & Son Perpetual Moon “Year of the Ox” Limited Edition

Like all the movements used by Arnold & Son, the calibre A&S1512 was entirely developed, produced, assembled, decorated, adjusted and cased up in the brand’s Manufacture in La Chaux-de-Fonds. This calibre is based on a large barrel with an oscillation frequency of 3 Hz, giving a 90-hour power reserve.

Last but not least, the moon-phase display of this movement will remain accurate for 122 years before deviating by one day from the actual appearance of the moon in the night-sky.

Arnold & Son Perpetual Moon Obsidian Limited Edition

Arnold & Son presents Perpetual Moon Obsidian, which boasts a beautiful made from Mexican obsidian and a large moon-phase complication. The stone is reflected in the large rhodium-plated moon and the perfectly polished hour-markers.

The Arnold & Son Perpetual Moon Obsidian stands out for the size of its moon-phase complication and the aesthetic approach employed by the resolutely British Swiss brand.

Arnold & Son Perpetual Moon Obsidian Limited Edition

The 42 mm red gold case houses a precise hand-wound calibre A&S1512. On the movement side, a hand display allows for extremely fine adjustments. On the dial side, a large moon disc occupies almost the entire aperture, presented in a vast window with a round cut-out that allows the changing faces of the moon to be admired.

Arnold & Son Perpetual Moon Obsidian Limited Edition

The realistic depiction is crossed by shadows and areas of relief to add to its presence. The moon is only visible because it reflects the light from the sun. In the same way, the light brings the Perpetual Moon Obsidian to life with its shimmering reflections.

Arnold & Son Perpetual Moon Obsidian Limited Edition

The golden obsidian stone was sourced from Mexico. This volcanic stone has been mined in Central America since time immemorial and was used in particular in the religious ceremonies of pre-Columbian civilisations.

Arnold & Son Perpetual Moon Obsidian Limited Edition

Obsidian has high silica content, making it a hard and shiny material. Its bronze hue extends far beneath the surface, right into the heart of the material. Despite the minute amount used for the dial, it still produces a glistening effect, reflected in turn in the hands and hour-markers.

Arnold & Son Perpetual Moon Obsidian Limited Edition

Arnold & Son selected cool shades to contrast with the stone. The moon and hands are rhodium-plated and the hour-markers are made from diamond-polished white gold. Together, these choices enhance the reflections of the golden obsidian and the red gold of the case. To complete this contrasting interplay of warm and cool tones, the brand chose a blue alligator-leather strap with visible silver-coloured topstitching.

Arnold & Son Perpetual Moon Obsidian Limited Edition

Like all the movements used by Arnold & Son, the calibre A&S1512 was entirely developed, produced, decorated, assembled, adjusted and cased up in the brand’s manufacture in La Chaux-de-Fonds. This calibre is based on a large barrel with an oscillation frequency of 3 Hz, giving a 90-hour power reserve. The moon phase display of this movement will remain accurate for 122 years before deviating from the actual lunar cycle by one day.

This watch is available in a limited edition of 28 pieces.

Arnold & Son Ultrathin Tourbillon Koi

Arnold & Son presents the Ultrathin Tourbillon Koi, a delicate unique piece that blends fine watchmaking and the artistic crafts. This red-gold timepiece with a mother-of-pearl dial highlights hand-painted carps and sculpted lotuses surround a flying tourbillon.

Highlighting the brand’s tradition of bespoke watch creations, this creation showcases a broad spectrum of skills within a red-gold case measuring 8.34 mm thick.

Arnold & Son Ultrathin Tourbillon Koi watch

Arnold & Son offers the customers the chance to personalise the watches. Customers can apply substantial changes, making a case, movement or dial unique through engraving, gem-setting, miniature painting or sculpted elements. The brand’s iconic Ultrathin Tourbillon watch features a spacious dial surface with its off-centred dial at 12 o’clock. This arrangement provides an empty canvas that can be filled with whatever the customer desires.

Arnold & Son Ultrathin Tourbillon Koi

Koi are a popular theme in traditional Japanese art and inspire tranquility. Above and beyond their beauty and serenity, they are a symbol of perseverance in the face of adversity.

Arnold & Son Ultrathin Tourbillon Koi

A Tancho carp, recognisable thanks to the large red mark on its head, swims on the right-hand side of the dial. Peering out from beneath the sleeve, it is the first to be seen when checking the time. The scene continues with another koi in shades of white and orange gracing the other side of the dial.

Arnold & Son Ultrathin Tourbillon Koi

Above these ornamental carp float three lotus blossoms. The petals are cut from silver and shaped, before being engraved, polished and painted in dazzling white lacquer. Each flower’s pistil is formed separately using the same techniques, then the two parts are combined.

Arnold & Son Ultrathin Tourbillon Koi

The carp and lotus leaves, meanwhile, are painted by hand using incredibly thin brushes that allow a wealth of details to be added, such as scales, barbels and striped fins. The base of the dial is made from blue-toned mother-of-pearl, its iridescent shimmer evoking the water in which this charming scene unfolds.

Arnold & Son Ultrathin Tourbillon Koi

The Ultrathin Tourbillon Koi watch has a 42mm red gold case and it houses the calibre A&S8200, an ultra-thin haute horlogerie movement with a thickness of 2.97 mm. Despite its compact size, this manually wound movement delivers an exceptional 90-hour power reserve. The movement displays the hours and minutes in an off-centred dial at 12 o’clock. At 6 o’clock, an aperture reveals a tourbillon whose construction is special in more ways than one.

Arnold & Son Ultrathin Tourbillon Koi

First and foremost, the tourbillon is a ‘flying’ variety, meaning that it only has a lower carriage bridge. Since the top is not held in place, a few precious millimetres of height can be saved, thus freeing up the view of this timekeeping mechanism. The balance, meanwhile, is off-centred from the carriage axis, creating a dynamic visual impression as the tourbillon rotates.

Arnold & Son Ultrathin Tourbillon Koi

Another distinctive feature is the balance bridge, which is domed and extends slightly from the dial, ensuring that the rest of the movement is unaffected by the total height. This, in turn, makes the tourbillon’s rotation all the more spectacular. The effect is further accentuated by the skeletonised main plate located just beneath the tourbillon.

The watch is worn on a hand-stitched alligator leather strap with an 18-carat red gold (5N) pin buckle.

Arnold & Son Nebula 38 Steel

The Nebula 38 is a harmonious yet striking skeleton watch, which fully expresses Arnold & Son’s identity as a Swiss watchmaker with English roots. Its open worked movement ties it to the great tradition of British watchmaking, while its design methods and finishes reflect the very best of Swiss quality.

Following the launch of a red-gold version, the 38 Nebula watch is now available in steel.

The Nebula 38 features a classic three-hand layout indicating the hours, minutes and off-centred small seconds. But in terms of complexity, this timepiece constitutes one of the most graphically striking, high-impact and original skeleton watches.

Arnold & Son Nebula 38 Steel

The open-worked A&S5101 calibre is the major aesthetic attraction of this timepiece. The dial is reduced to a black lacquered flange, while the calibre the steals show with its arrangement, layers and curves, its juxtaposed materials and play on solids and hollows.

The structure of the A&S5101 calibre is based on carefully considered symmetry. Seven bridges span the four axes that cross the Nebula 38, creating a sense of visual balance. Measuring a diameter of 38 mm and a thickness of 8.91 mm, the steel case features a domed sapphire crystal on the dial side and a flat sapphire crystal on the case back.

Arnold & Son Nebula 38 Steel

On the dial side, you can admire the clear view of well structured movement components like a double barrel bridge, crown bridge, balance bridge, gear-train bridges. While all these bridges dialogue with each other on opposing axes within the movement, the functional elements also adhere to this mirrored design.

The small-seconds function at 7 o’clock, for example, is twinned with the balance. While technically different, these two blocks adopt similar shapes to perfect the movement’s sense of equilibrium. The harmony is plain to see, as all the bridges, plates and solid components are open-worked.

Arranging the structures of a skeleton movement in a ring facing inwards is a unique approach. Furthermore, to maintain the sense of symmetry, Arnold & Son moved the winding mechanism linked to the crown stem to the case back, giving it an unusual position that is entirely justified for the overall aesthetic coherence it procures. In spite of this, the Nebula 38 was designed with practicality in mind, as it presents a 90-hour power reserve that is rare for skeleton models.

Arnold & Son style has used a variety of colours, finishes and levels to maintain excellent legibility of this timepiece. The bridges are thus all the same height on the dial side. On the case-back side, a large sapphire crystal reveals a mainplate that has been open-worked to the extreme. Its design features several criss-crossing arcs, with intersecting circles and ellipses that are reminiscent of a Gothic cathedral’s vault.

Arnold & Son Globetrotter Night

In the 1780s, John Arnold contributed to the great revolution in ocean navigation with his marine chronometers.

The Globetrotter Night reflects this historical legacy with its cartographic features and world times. As night follows day, Arnold & Son cloaks its Globetrotter in darkness, spectacularly showcasing our northern hemisphere when shrouded in vesperal shadow.

Beneath a large sapphire crystal dome, an arch supports a half-globe in shades of grey and blue. It depicts the continents, the seas and the lights of the large cities located north of the equator. On the edge of the planet, a sapphire ring breaks down the 24 hours of a day.

Transparent between 6 am and 6 pm, a metal treatment has been used to darken it, indicating the night-time hours. Together, the hemisphere and ring display the time in one part of the world, represented in a highly original way. In the absence of a dedicated hand or city disc, the time is read geographically in accordance with the continents.

Arnold and Son Globetrotter Night watch in stainless steel

The Globetrotter Night offers a realistic and meticulously rendered interpretation of a three-dimensional map enclosed in a 45 mm steel case. Chemical engraving has been used on the half-globe to outline the continents.

The raised parts have undergone a deep-grey galvanic treatment before being hand-lacquered in a black-grey hue, while the oceans are lacquered in grey-blue. Finally, the city lights twinkling in the northern hemisphere are represented by hand-applied silver sparkles.

Arnold and Son Globetrotter Night watch in stainless steel

The decorative touches and finishes adorning the Globetrotter Night extend beyond the Earth itself. The chapter ring is circular satin-brushed and the hands, despite being mostly concealed beneath the half-globe, are polished and accentuated by red lacquered tips.

The large double-foot bridge supporting the half-globe is a spectacular feature in itself that lends structure to the overall appearance of this timepiece. It is circular satin-brushed and chamfered by hand and held in place by screws with polished heads and chamfered slots.

Arnold and Son Globetrotter Night watch in stainless steel

These finishes are echoed extensively on the A&S6022 self-winding calibre powering the Globetrotter Night. Entirely developed and produced by the Arnold & Son Manufacture, it has a nocturnal style thanks to the widespread use of NAC-type surface treatments.

The bridges are polished and chamfered, finished with Côtes de Genève stripes and coloured grey. The skeletonised oscillating weight is engraved and treated chemically with ADLC black and NAC grey to obtain a two-tone appearance using a matt straight-grained finish.

Beyond these aesthetic details, what makes the A&S6022 calibre special is its easy setting, thanks to a three position crown. The first winds the movement.

The second adjusts the local time hand by one-hour jumps either clockwise or anti-clockwise. The third regulates the hours and minutes in addition to the planet’s rotation. When travelling to a different time zone, the second position enables the wearer to change local time while keeping world time synchronised.

In the interests of fairness, Arnold & Son can also provide a “southern hemisphere” version of its Globetrotter Night on request at the same price.

Arnold & Son DSTB Only Watch 2019 Unique Piece

In 2019, for the second consecutive year, Arnold & Son is supporting the Monegasque Association against Muscular Dystrophy by participating in the Only Watch auction.

For the occasion, the brand based in La Chaux-de-Fonds has created a unique edition of its Dial Side True Beat model, better known by the acronym DSTB.

Arnold & Son chose this piece in particular to highlight the infinite treasures of every second and to celebrate life. Each short second also serves to underscore the long periods of time devoted to scientific and medical research into muscular dystrophy.

Arnold and Son DSTB Only Watch 2019 Unique Piece

The DSTB will be auctioned in Geneva on Saturday 9 November 2019.

Arnold & Son’s DSTB model calls on the watchmaking science of John Arnold, a British watchmaking genius active in the late 18th century. Throughout his career, he focused his efforts on the quest for extreme chronometric accuracy.

Arnold and Son DSTB Only Watch 2019 Unique Piece

John Arnold garnered renown in part for his marine chronometers, which naturally featured a “dead-beat second” mechanism – more favourably known as a “true second” hand. This complication involves the second hand making 60 jumps per minute. It makes pronounced jumps from marker to marker instead of following the rhythm set by the oscillator frequency, which moves the hand several times per second and results in a continuous second.

As the display always points to a readable marker on the minute circle, it allows for an extremely precise reading, recalling both regulator-style workshop clocks and marine chronometers. Both of these kinds of timepieces had to be extremely precise as well as clearly legible.

Despite being a common feature in quartz watches, where it is used to save energy, it is exceptionally rare for a true second to be added to a mechanical calibre – making it an utter delight for lovers of traditional watchmaking. Arnold & Son offers this complication on several models, one of which in particular has made a name for itself.

Instead of incorporating it into the movement, the DSTB places the entire true seconds mechanism on the dial side, making it easy to understand and, above all, spectacular.

The components of this unusual display can be found under a large transparent sapphire circle punctuated with light sky-blue indexes. To produce these precise components, the brand had to call on LIGA production technology, where, instead of being machined, the parts are formed using a technique reminiscent of microprocessor production.

Arnold and Son DSTB Only Watch 2019 Unique Piece case back view

The system operates in a similar way to a detent escapement. The movement drives an indirect seconds’ wheel with a lever fitted with a counterweight. This is connected to a lever ending in a ruby pallet stone. Every second, the energy accumulated lifts up the pallet stone, which allows the true seconds wheel and hand to move forwards by one notch. A spring then returns the lever to its place.

At the heart of the system, an anchor plays the highly visible role of counterweight. A symbol of the House and featured in its logo, the anchor serves as a reminder of the watchmaking roots of John Arnold, who devoted years of work to marine chronometers.

As only befits a watch donated to the Monegasque Association against Muscular Dystrophy, the DSTB Only Watch edition is a unique piece. It is characterised by its brushed anthracite DLC-treated steel case, its calfskin strap whose turned-out stitched seam is aligned with the off-centred hour and minute dial, and of course by the light sky-blue details chosen as the theme of Only Watch 2019.

Arnold and Son DSTB Only Watch 2019 Unique Piece

But Arnold & Son has gone further still in the pursuit of uniqueness. The winning bidder for the DSTB Only Watch will be invited to choose the shape of the true seconds counterweight to replace the anchor-shaped piece.

Arnold & Son will then produce the component in question – after carrying out the necessary specific development and production processes – and incorporate it into the timepiece. The piece will then be both unique and personal.

Arnold & Son Nebula 38 mm

Arnold & Son reinterprets its emblematic, symmetrical skeleton Nebula in new proportions.

The three-dimensional, openwork movement and dial of the Nebula offer views into the very heart of the in-house manufacture calibre. Its gold case has been reinvented in a 38 mm diameter, magnifying the hypnotic micro-mechanical spectacle of the hand-wound movement.

Arnold and Son Nebula 38mm watch in 18k red gold

Besides the careful attention to equilibrium, the powerful allure of the Nebula also derives from the calculated proportions and ratios of diameter versus height, size and placement of every gear and wheel.

Rather than being an assembly of disparate components – case, dial, and movement – Nebula was designed from the ground up to be completely holistic, with all components blending harmoniously into one. For instance, no less than ten bridges of this complex calibre form the dial.

Arnold and Son Nebula 38mm watch with red gold case

Highly legible hours and minutes rotate above the movement conceived and developed from the outset to be open rather than have superfluous material skeletonized as an afterthought. The revised sloping chapter ring and faceted golden indexes complete the impactful visual effect of the Nebula 38mm.

The balanced construction of A&S 5101 calibre – horizontally and vertically symmetrical, both front and back – explains the watch lovers’ strong attraction to the refined Nebula 38mm.

On the dial side, symmetry at top to bottom is provided by the two mainspring barrels, which provide a very healthy 90 hours of power above, and small seconds plus the oscillating balance wheel below. Seven of the skeletonized and chamfered triangular bridges with polished edges fixed around the perimeter of the movement and radiating inward, offer a contemporary take on traditional architecture.

Arnold and Son Nebula 38mm watch red gold

Not only is all of the movement visible and highly decorated – barrels, gear train, balance and escapement, and winding mechanism – can be appreciated from the dial side. The view through the display back reveals even more finishing, with skeletonized and chamfered main plate with polished edges, solid 18-karat gold settings and gears featuring polished chamfers.

Arnold & Son Time Pyramid Tourbillon

Deftly blending its British heritage with its Swiss watchmaking savoir-faire, Arnold & Son offers a new calibre to its Time Pyramid collection. With a skeletonized pyramid-shaped tourbillon seemingly floating between two sapphire crystals, the Time Pyramid Tourbillon is a true rendition of technical prowess and sleek elegance.

Arnold and Son Time Pyramid Tourbillon watch stainless steel version

The Time Pyramid Tourbillon presents a cohesive combination of watchmaking feats organized in a pyramidal architecture. The skeletonised calibre A&S8615 pays tribute to the John Arnold’s regulators with their distinctive hours, minutes and seconds on different axes.

The movement is built on three levels. The tourbillon and the two power reserve indicators are superposed by a sapphire crystal dial indicating the hours itself, crowned with a rhodium plated ring for the minutes. This exclusive construction offers a lively-look and three-dimensional face to the timepiece and, to further enhance the balance and symmetry, the crown is positioned at six o’clock.

Arnold and Son Time Pyramid Tourbillon watch 18K red gold version

The gear train runs vertically in a linear arrangement connecting the two barrels at six o’clock to the tourbillon escapement at twelve o’clock, giving the movement its pyramidal architecture. The bridges are designed so that all the wheels, the two mainspring barrels, the escapement and balance wheel are all visible from the dial side.

Arnold and Son Time Pyramid Tourbillon watch stainless steel model

Besides the off-centred hours and minutes, seconds are on the tourbillon and the two power reserve indicators on each side of the linear gear train indicates the energy level of the two mainspring barrels. The blued steel hands indicating these power reserves artfully demonstrate how the right barrel takes over when the left barrel reaches a limited power and thus, to maintain an optimum and accurate functioning. The two serially set up barrels supply the in-house manufactured calibre with a total of 90- hour power reserve and provide a more regular force to the wheel train.

Arnold and Son Time Pyramid Tourbillon watch 18k red gold model

To meet with Arnold & Son finishing standards, the movement of the Time Pyramid Tourbillon is decorated with chamfered bridges, polished edges and Côtes de Genève while the main plate is satin-finished, the A&S three-spoke wheels chamfered, the edges polished, and the screws blued. The top bridge and cage plate of the tourbillon are circular satin-finished, chamfered and mirror-polished by hand.

The Time Pyramid Tourbillon is housed in a 44.6 mm diameter 18-karat red gold or stainless steel case and adorned with a hand-stitched alligator strap.

Arnold & Son HM Perpetual Moon Aventurine, New Red Gold Version with Blue Aventurine Stone Dial

Demonstrating its rich British history and quality Swiss craftsmanship, Arnold & Son unveils a new version of the HM Perpetual Moon with a blue Aventurine stone dial.

The HM Perpetual Moon is a testament to Arnold & Son’s tradition of watches with astronomical indications. Like all timepieces in the Arnold & Son Royal Collection, this new model demonstrates the brand’s prowess in traditional watchmaking and classical decorative arts.

Arnold and Son HM Perpetual Moon Aventurine, New Red Gold Version with Blue Aventurine Stone Dial

From the inside out, this new timepiece with rich blue guilloché moon disc and engraved moon surprises and delights. It houses the exclusive Arnold & Son mechanical hand-wound movement, the calibre A&S1512.

This calibre was especially developed for Arnold & Son moonphase watches with the objective of offering a uniquely precise, big and three-dimensional moonphase. The calibre is also equipped with a double barrel to yield 90 hours of power reserve.

Arnold and Son HM Perpetual Moon Aventurine, New Red Gold Version with Blue Aventurine Stone Dial

The HM Perpetual Moon Aventurine offers one of the most accurate moon phases on the market, with only one day’s deviation every 122 years at which point a single push on the corrector will keep it in sync for another 122 years.

The exceptional perpetual moonphase indication of this watch is a marvel in many ways. From the aesthetic side, the 29 mm moonphase disc, which runs from 10 to 2 o’clock on the dial, reveals one of the largest moons on the market with a diameter of 11.2 mm for the moon alone.

Additionally, this large moon is one of the most visually stunning recreations of the moon because it is a three-dimensional sculptured moon that was first hand-engraved and then duplicated in a 18k red gold plate for the series. The sculptured moon is then inserted into the guilloché disc.

From the technical side, in addition to the HM Perpetual Moon Aventurine being so precise, it is also an intriguing complication in that it is not simply a module added to the movement, but, in fact, is fully integrated into the calibre.

The watch also has a unique easy-to-set feature thanks to the ingenious addition of a second moon indication installed at the back of the movement. This second moon display, visible via a transparent case back, features a graduated dial and a pointer hand that allows a more exact setting.

The multiple technological advancements in the calibre make this timepiece truly outstanding. To further underscore that, the entire rhodium treated nickel-silver movement features hand finishing indicative of the finest Haute Horlogerie timepieces, including manually chamfered bridges with polished edges, Côtes de Genève rayonnantes and fine circular graining, circular grained wheels, and blued screws with polished and chamfered edges. The timepiece naturally features an anti-reflective sapphire crystal and case back to view the meticulous details.

The HM Perpetual Moon Aventurine measures 42 mm in diameter in its classically elegant Red Gold (5N) case. Viewed from the side, the housing is stepped and tapers from top to bottom, the widest section accommodating the extra-large glass with the lower part narrowing to fit snugly on the wrist.

Each timepiece is finished with an exquisite hand stitched alligator strap.

Arnold & Son Time Pyramid Black Edition

The Time Pyramid from Arnold & Son Instrument Collection is now available in a new Black Edition in striking black and gold tones featuring a black DLC treated stainless steel case.

The Time Pyramid watch draws inspiration from the regulators built by John Arnold over two centuries ago, as well as English skeleton clocks.

Originally conceived in the middle of the 19th century, such lavishly executed clocks showcased the mastery and unique aesthetical sense of English watchmakers. As ornamental as they were functional, English skeletonized clocks were prized for their sculptural and symmetrical construction, allowing for an unobstructed view of the beating mechanisms.

Arnold and Son Time Pyramid Black Edition watch

Reinterpreting the three-dimensional beauty of such antique skeleton watches in a format adapted for wristwatches resulted in the Arnold & Son skeletonized caliber A&S1615. Built in a unique format, the balance wheel is positioned at twelve o’clock, and at the opposite end of the movement at six o’clock, two mainspring barrels that supply the hand-wound caliber with an amazing 90 hours of power reserve, and provide a more constant force to the wheel train.

Arnold and Son Time Pyramid Black Edition watch

The gear train runs vertically in a linear format connecting the two barrels at sixo’ clock to the balance wheel at twelve o’clock, and endowing the movement with its pyramid structure. The bridges are designed so that all of the wheels, the two mainspring barrels, the escapement and balance wheel are all magnificently visible from the dial side.

Arnold and Son caliber A&S1615 hand-wound skeleton movement

Additionally, the movement is fitted with two power reserve indicators – one each on either side of the linear gear train – to display the energy level for each barrel separately. The power reserve hands indicate the reserve level via graduated dots (that are printed under the top sapphire crystal) in an arc format, and demonstrate how one barrel transfers energy to the second one when needed.

Housed in a 44.6mm Stainless Steel case with a black DLC coating, the movement has been reimagined with a blend of muted black and warm rose gold tones, highlighting the movement’s unique architecture while playing with light in a most fascinating manner.

Arnold and Son Time Pyramid Black Edition watch

The movement’s main plate and bridges are treated in black ADLC, while still retaining classical haute horlogerie decoration such as Côtes de Genève strips and chamfered, polished edges. The various wheels of the symmetrical gear train as well as the barrels are given a rose gold treatment, as are all the hands and the frame holding the sapphire hours and minutes dial.

The Arnold and Son Time Pyramid Black Edition watch comes fitted with a hand-stitched black alligator leather strap, with a black DLC treated steel tang buckle matching the case.

This timepiece is limited to 50 pieces.

Arnold & Son Nebula Lady

The Nebula Lady from Arnold & Son is a fine skeleton timepiece exclusively made for ladies who appreciate fine mechanical watch making.

Besides the evident careful attention to balance, the powerful allure of the Nebula also derives from the meticulously calculated proportions and ratios of diameter versus height and the size and placement of every gear and wheel.

Rather than being an assembly of disparate components – case, dial, and movement – Nebula was designed from the ground up to be completely holistic, with all components blending harmoniously into one. The “dial” actually acts as a bridge in supporting some of the intricate gearing.

Arnold and Son Nebula Lady watch red gold with diamond set case

The movement bridges − there are no less than ten in this complex caliber, compared to four in a standard watch − form the dial.

More than just a superficial surface coating, the bridges of the Nebula Lady are crafted from solid 18-karat Red Gold, with beveled and polished edges. Set against a silvery palladium-tone base plate, a subtle play between cool silvery tones and warmer gold accents transforms the Nebula’s open display into an alluring and feminine masterpiece of mechanical art.

In the Nebula Lady, the highly legible central hours and minutes hands as well as the small seconds hand are given a black treatment, as are the applied faceted and polished hour markers to provide a bold contrast against the palladium chapter ring surrounding the open movement display.

Arnold and Son Nebula Lady watch in diamond set red gold case

From the dial side, symmetry at top to bottom is provided by the two mainspring barrels, which provide 90 hours of power above, and small seconds plus the oscillating balance wheel below.

Seven of the skeletonized and chamfered triangular 18kt Red Gold bridges with polished edges fixed around the perimeter of the movement and radiating inward offer a contemporary take on traditional English movement architecture.

The 41.5mm red gold case is adorned with 90 brilliant cut white diamonds with a total weight of approximately 0.52 carats, meticulously set onto the bezel. The Nebula Lady comes on a white calf leather strap.

Arnold & Son Globetrotter (Instrument Collection)

Inspired by the high-precision marine chronometers made by John Arnold and his son towards the end of the 18th century, Arnold & Son presents Globetrotter, the timepiece for the modern-day navigator.

Held by a large central arched bridge spanning the entire diameter of the dial, the Globetrotter’s three-dimensional world-time display takes centre stage. At 45 mm wide and 17.23 mm at its highest point, the Globetrotter features one of the world’s largest rotating 3D world-time display on a wristwatch.

Arnold and Son Globetrotter watch

It depicts the view of Northern Hemisphere as seen from space as if directly above the North Pole. Starting with a rounded piece of brass, the different textures of the oceans and continents are brought out by chemical etching with a mask, followed by polishing the upper surfaces.

The mountainous areas are then sandblasted to create a sense of visual depth, and then the oceans are lacquered by hand with different blue tones. The entire world-time disk is then treated with a layer of clear lacquer, and finally the entire component is polished. The result is a hemispherical disk full of lifelike details.

Arnold and Son Globetrotter watch

Seemingly floating above a silvery-white opaline dial with Roman numerals for the hour hand and a circular brushed chapter ring for the minutes, the world-time display is surrounded by a 24-hour sapphire disk fixed to the same bridge that hold the hemisphere, transparent between 06:00 and 18:00 and with a translucent metallic treatment from 18:00 to 06:00, serving as a day and night indicator. The world-time makes one complete rotation every 24 hours.

Intuitive to read and adjust, the Globetrotter features a three-position crown system. The first position is used to manually wind the movement, the second position sets the local time (hour hand) in one-hour increments, and the final position is used to set the hour and minute hands and the world-time. Both the main time display as well as the world-time function can be adjusted forwards and backwards.

Arnold and Son Globetrotter watch

To keep the focus of the dial on the world-time display, the hour and minute hands, in blued steel are placed under the hemisphere, as if circling in its periphery. To enhance legibility, the hands are filled with red lacquer.

The Arnold and Son Globetrotter watch is housed in a stainless steel case measuring 45 mm in diameter, with a thickness of 17.2 mm including the domed sapphire “glass box” crystal, and 10.4 mm without the crystal.

Arnold & Son caliber A&S6022 self-winding movement

Entirely developed and manufactured by Arnold & Son, the Globetrotter’s A&S6022 features an automatic winding system by means of a central, rotor, engraved with a hobnail motif with a black ADLC treatment. When fully wound, the movement provides a power reserve of 45 hours.

The NAC grey treated movement features Haute Horlogerie finishing with hand-chamfered and satin-finished lever and bridges, polished edges and fine circular graining and Côtes de Genève stripes radiating from the center.

Arnold & Son Tourbillon Chronometer No.36 Tribute Editions

Arnold & Son pays tribute to the revered John Arnold Chronometer No. 1/36 with two commemorative tribute editions of the Tourbillon Chronometer No.36.

2018 marks 240 years since the creation of John Arnold’s historically significant Chronometer No. 1/36, the first time-measuring instrument to be called a “chronometer” for its unprecedented precision.

Created to mark the historical milestone, the modern homage edition of the Tourbillon Chronometer No.36 is a COSC-certified wristwatch, a rarity among tourbillon watch models.

Arnold and Son Tourbillon Chronometer No.36, Tribute Edition Red Gold watch

The first commemorative edition of the Tourbillon Chronometer No. 36 unveiled last year featured a more traditional English frosted gilt finish on the movement, produced as a limited edition series that immediately become a must-have for aficionados of Arnold & Son timepieces and precision chronometers.

The 240th anniversary Tribute Edition of the Tourbillon Chronometer No.36 offers the opportunity to acquire this exceptional and contemporary reinterpretation of John Arnold’s revered chronometer, and thus will be produced as a non-limited production series in red gold and stainless steel models.

Arnold and Son Tourbillon Chronometer No.36, Tribute Edition Red Gold watch

The John Arnold Chronometer No. 1/36 or “Arnold 36” as it is more commonly called was not only the first pocket watch by John Arnold to use a larger movement with his compensation “T” balance, but also the first to be referred to as a “chronometer” for its extraordinary timekeeping performance.

A technical revolution at the time, the John Arnold No. 1/36 built in 1778 displayed vastly superior chronometry compared to every other watch at the time, that after the hugely successful 13-month trials at the Greenwich Observatory in 1779, John Arnold coined the term “chronometer” to refer to the No. 1/36 pocket chronometer, which marked a new era of unprecedented precision in timekeeping.

In this respect, the Tourbillon Chronometer No.36 pays tribute to the legendary high-precision chronometer in a faithful yet contemporary manner.

Arnold and Son Tourbillon Chronometer No.36, Tribute Edition Red Gold watch

John Arnold (1736-99) successfully found the way to simplify Harrison’s timekeeper design. This watch, No 1/36, made in 1778, went so well on trial at Greenwich that Arnold decided to give it a new name.

In the pamphlet he published in 1780 advertising his achievement, he called the timekeeper a ‘chronometer’ and was thus the person who invented the term in its modern sense. The watch is in fact a pocket chronometer housed in a 22-carat gold case.

Following the classical codes of traditional English chronometer movements, the main pivoting elements such as the wheels, barrels, the tourbillon, and others are each mounted on their own bridge. The triangular, multilevel bridges (no less than thirteen) are mostly skeletonized, providing a more contemporary sense of three-dimensional depth to the entire timepiece.

Arnold and Son Tourbillon Chronometer No.36, Tribute Edition Stainless steel watch

The tourbillon, a central element of this timepiece, is highlighted in a most magnificent manner. Held by a skeletonized and mirror-polished top bridge, the one-minute tourbillon features a typically Arnold & Son three-spoke design.

Weighing mere fractions of a gram, the tourbillon cage consists of no less than 58 components. Prominently positioned on the dial side, the tourbillon can also be viewed from the back, thanks to an opening in the main plate. The same kind of opening is made below the small seconds display, adding to the symmetry of the Tourbillon Chronometer No.36.

The entirely in-house conceived and manufactured A&S8600 movement features a lightly grained sand-blasted main plate treated with a main plate in NAC grey in the Red Gold version, while the Steel version has a more contemporary black DLC surface.

The bridges are satin-brushed with chamfered and polished edges, and are done in a lighter palladium tone on the Red Gold version, and NAC grey in the Steel version. The main plate also is set with several mirror-polished 18k white gold chatons, while the wheels in the gear train are embellished with circular satin finishing with chamfered and polished edges. Even the screws are beveled and feature with mirror-polished heads.

The double barrels, embellished with laser-engraving decoration, provide a considerable power reserve of 90 hours when fully wound.

Arnold & Son DBG Skeleton Limited Edition

Arnold & Son unveils a new rendition of its unique DBG dual-time (GMT) timepiece, the DBG Skeleton.

An acronym for “double balance” and “GMT”, the DBG Skeleton – a part of the Instrument Collection – references the precise chronometers built by John Arnold and his son.

With a new skeletonized execution, the DBG Skeleton showcases Arnold & Son’s watchmaking prowess as well as attention to aesthetic details with the newly developed manufacture A&S1309 calibre, which has been conceived, designed and manufactured entirely in-house.

In this timepiece, the lavishing skeleton work reveals exquisite artistic detail, from the blued screws to the Côtes de Genève stripes and satin finish running across the bridges and edges of the dial.

A masterpiece of perfect symmetry, the DBG Skeleton features two separate time displays, each driven by its own barrel and gear train with its own escapement and balance, now entirely visible thanks to its openworked execution. This highly unusual technical specification permits the two displays to be set independently of each other.

Although it is a standard feature of watches displaying two or more time zones for the hour hands to be set to different times, being able to set the minute hand as well opens up other possibilities.

It means, for instance, that the display can be set to show the precise time in zones that differ from Greenwich Mean Time by a fraction of an hour, such as a quarter or a half. In addition, a subdial at 12 o’clock shows the equation of the two time zones on a 24- hour basis.

This enables the wearer to see the time difference between the two zones and also to ascertain whether it is day or night in the second zone. Both time zones share a common permanent seconds hand placed at the centre of the dial.

Watches with a double barrel and escapement have a tradition going back many years in horology but are rarely found today.

Historically referred to as a “captain’s watch”, the principle is ideally suited to the Arnold & Son’s instrument line because a separate barrel/gear train and balance/escapement enable the watch to house different complications without having one influencing the accuracy of the other by draining its energy. It is therefore perfectly adapted to be used for a second time zone, as in the DBG Skeleton.

No less impressive than the watch’s technical features is its aesthetic appeal, and in particular its symmetry, which is largely determined by the positioning of the elements in the dual movement, visible from both sides of the watch. The entire movement was designed so as to enhance its visual appeal when skeletonized. The view from the back reveals a pleasingly balanced arrangement of open bridges, barrels and gear trains.

From the front, and highlighted against a backdrop of Côtes de Genève stripes on the lower half of the dial, are two triple-armed balances secured in position by the two balance cocks, which face one another and fuse together to create a circle.

Arnold and Son Calibre A&S1309 skeleton movement

The open dials featuring Arabic numerals for one time zone and Roman numerals for the other are made of “smoked” metal-treated sapphire crystals, allowing both transparency as well as legibility. Completing the overall sense of balance are the two crowns, one in the conventional position at 3 o’clock, the other at 9. The two mainsprings are both wound using the crown on the right.

Arnold and Son Calibre A&S1309 skeleton movement

However, the time in each of the two selected time zones is set using its own crown, which ensures that neither of the zones is moved or changed inadvertently. The time zone on the left is set using the crown at 9 o’clock and the time zone on the right by the crown at 3 o’clock.

Arnold & Son Tourbillon Chronometer No. 36 Limited Edition

With the Tourbillon Chronometer No. 36, luxury watchmaker Arnold & Son pays tribute to the historical high-precision chronometers made by legendary master watch maker John Arnold.

Drawing inspiration from the John Arnold pocket chronometer No. 1/36, which will mark its 240th anniversary in 2018, the Tourbillon Chronometer No. 36 is a commemorative creation leading up to the milestone year for the historically significant John Arnold chronometer.

Arnold and Son Tourbillon Chronometer No.36 limited edition watch in red gold

The John Arnold Chronometer No. 1/36, also known as “Arnold 36”,  was not only the first pocket watch by John Arnold to use a larger movement with his “T” balance, but also the first to be referred to as a “chronometer” for its superior timekeeping capabilities.

In this respect, the Tourbillon Chronometer No. 36 is faithful, contemporary horological homage. Following the classical codes of traditional English chronometer movements, the main pivoting elements such as the wheels, barrels, the tourbillon, and others are each mounted on their own bridge.

The triangular, multilevel bridges (no less than thirteen) are mostly skeletonized, providing a more contemporary sense of three-dimensional depth to the entire timepiece.

Arnold and Son Tourbillon Chronometer No.36 limited edition watch in red gold

The tourbillon, a central element of this timepiece, is highlighted in a most magnificent manner. Held by a skeletonized and mirror-polished top bridge, the one-minute tourbillon features a typically Arnold & Son three-spoke design. Weighing mere fractions of a gram, the tourbillon cage consists of no less than 58 components.

Prominently positioned on the dial side, the tourbillon can also be viewed from the back, thanks to an opening in the main plate. The same kind of opening is made below the small seconds display, adding to the symmetry of the Tourbillon Chronometer No. 36.

Arnold and Son Tourbillon Chronometer No.36 limited edition watch in stainless steel

The apparent technical virtuosity of the Tourbillon Chronometer No. 36 is not only a treat for the eyes, as the watch is a COSC certified chronometer; something of a rare achievement for a tourbillon-equipped timepiece.

Arnold and Son Tourbillon Chronometer No.36 limited edition watch in red gold

The decorative haute horlogerie arts are also lavishly demonstrated in the Tourbillon Chronometer No. 36. The entirely in-house conceived and manufactured A&S8600 calibre features a smooth sand-blasted main plate and bridges with chamfered and polished edges.

Arnold and Son Tourbillon Chronometer No.36 movement

The main plate and bridges are treated with a golden coating, echoing the aesthetics of the historical pocket watches made by John Arnold. The main plate also is set with several mirror-polished 18k gold chatons, while the wheels in the gear train are embellished with circular satin finishing with chamfered and polished edges. Even the screws are beveled and feature with mirror-polished heads.

The heart of the watch, the tourbillon, features a traditional construction with a top bridge, while the mirror-polished cage has the signature Arnold & Son three-spoke design, making a complete turn in 60 seconds. The double barrels, embellished with laser-engraving decoration, provide a considerable power reserve of 90 hours when fully wound.

Arnold & Son Instrument DSTB, New Stainless Steel Edition

Arnold & Son unveils a new stainless steel edition of the DSTB (Dial Side True Beat), an haute Horlogerie collection that demonstrates the brand’s rich British history and quality Swiss craftsmanship.

Equipped with an in-house mechanical movement and featuring the true beat seconds, a traditional complication of Arnold & Son, the DSTB watch pays tribute to the watches produced by John Arnold during the second half of his career, when he and his son were the first to develop marine chronometers that could be produced in quantity at reasonable prices.

Those technically superior, widely distributed chronometers reflected Arnold & Son’s commitment to exceptional precision and solved the problem of determining longitude at sea.

The newly designed automatic movement showcases the true beat seconds’ mechanism entirely on the dial side. Not just the hands, but also the lever, wheels and three palladium treated true beat seconds bridges are located in all their beauty on the dial side. Making the watch even more alluring is the fact that the true beat seconds lever is shaped like an anchor – paying homage to Arnold’s maritime achievements.

Arnold and Son Calibre A&S 6003 manual-wound movement

The true beat seconds are superbly indicated via a large sapphire dial that occupies the top left portion of the dial at 11 o’clock. At the 4 o’clock position, a domed and white lacquered subdial indicates the hours and the minutes via blued hands. These generously proportioned, overlapping indications translate into a stunning three-dimensional dial.

This restructuring of the intricate mechanism yields a concept not achieved in the watch industry heretofore. The self-winding calibre A&S6003 has 229 components.

In true Arnold & Son style, the palladium treated movement features Haute Horlogerie finishing with hand-chamfered and satin-finished lever and bridges, polished edges and fine circular graining and Côtes de Genève rayonnantes. The visible dial plate is blue PVD treated with large circular finishing, and screws with bevelled and mirror-polished heads.

Arnold & Son DTE Wins the ‘Best Multi-Time Zone Watch’ Award during the 12th Edition of the Middle East Premier Awards 2016

Swiss luxury watch brand Arnold & Son was among the winners of The Arabian Watches & Jewellery (AWJ) Magazine’s – the Middle East Premier Awards. The winners were announced in a glittering ceremony on 10th November 2016.

The Middle East Watch of the Year Awards is a pioneering concept initiated and implemented by Arabian Watches & Jewellery Magazine, alongside the Salon des Grandes Complications exhibition. The award ceremony was held on Thursday, 10th November at the Ritz-Carlton, Dubai International Financial Centre. The event was attended by over 400 distinguished high profile guests.

Arnold & Son was the winner in the category ‘Best Multi-Time Zone Watch’ for its DTE watch.

This refined Double Tourbillon Escapement Dual Time watch is a marvel of mechanical mastery and aesthetic elegance. François Picci, VP Sales of Arnold & Son accepted the award.

Arnold & Son DTE
Arnold & Son DTE

Renowned for its innovative technology and amazing technical prowess Arnold & Son continually brings horological excellence to new heights. Such is the case with the DTE, which joins the brand’s much-coveted Instrument Collection, whose signature is in-house manufactured movements inspired by the timepieces produced during the second part of John Arnold’s life when he and his son, John Roger, dedicated themselves to the quest for absolute precision.

Arnold & Son can easily be considered the father of modern marine timekeeping. Because of its technical superiority in watchmaking, Arnold & Son developed and produced chronometers that solved the  18th-century problem of determining longitude at sea (also, thereby establishing themselves as official suppliers to the Royal Navy).

Clearly one of the greatest watchmakers in history, John Arnold shared his knowledge and passion with Abraham-Louis Breguet. Evidence of their partnership is Breguet’s first ever tourbillon cage (No 169) mounted in John Arnold’s No. 11 movement, a watch that can be found today in London’s British Museum.

The DTE is a masterpiece of symmetry, balance and three-dimensional beauty combined with technical foresight and ultimate performance precision. The watch, powered by the all-new mechanical hand-wound calibre A&S8513, brings the centuries-old tradition of double movements back to life – in 21stcentury style. It features two separate time zone displays – each of which can be set independently from the other thanks to dedicated setting mechanisms. Each has its own gear train and its own tourbillon escapement.

In addition to the double tourbillon escapement and the dual dial/dual time indication, the watch is incredibly efficient in that it not only offers local time in hours and minutes, but also offers hours and minutes of a second time zone to be set separately – thereby enabling the wearer to have precise time in zones that differ from Greenwich Mean Time by quarter- or half-hour increments. The double barrels of the watch offer a superb 90 hours of power reserve.

In typical Arnold & Son style, the watch is incredibly detailed and features superlative Haute Horlogerie finishing. The dial side of the timepiece offers symmetry and depth. It features two white lacquered domed dials – one each at 12 o’clock and 6 o’clock  –  for the dual time displays. The two tourbillon escapements are harmoniously balanced at 3 o’clock and 9 o’clock and seem to float over the dial thanks to their alluring raised 18-karat red gold bridges.

The backdrop for these double lacquered dials and double tourbillon escapements is a magnificently decorated vertical Côtes de Genève stripes plate. The two crowns – one each for setting the local and the home time – are located at 2 o’clock and 8 o’clock, and the two mainsprings are wound using the crown at 2 o’clock.

The 43.5 mm DTE is created in 18-karat red gold. The white dials (with Roman numerals in one and Arabic numerals in the other) are accented with blued hour and minute hands.

The back of the watch features a transparent sapphire crystal for viewing the splendidly decorated nickel-silver movement. In all, this masterpiece of tradition and vision, of technology and elegance reinforces the watchmaking prowess of Arnold & Son, and elevates its accomplishments to all new heights.

John Arnold’s 23/78 Chronometer Sets a World Record at Sotheby’s Auction on 07 Jul 2016

On the 7th of July 2016 in London during the second part of Sotheby’s series of auctions dedicated entirely to English Watchmaking, a new world record was set for a John Arnold chronometer, fetching £557,000 GBP ($722,318 USD), more than multiple times its original estimate.

Completed in 1781, the John Arnold pocket watch numbered 23/78 is unique for a number of reasons. It features several inventions by John Arnold and other outstanding features including a pivoted detent escapement with a “double S” balance, a cylindrical balance spring, and a clever temperature compensation mechanism.

Furthermore, it is the only known example to have survived in its exact original condition without ever having undergone any restoration, with all parts including the silver case, enamel dial and movement perfectly intact and untouched. This extraordinary result achieved at Sotheby’s auction is an attestation to the pivotal role John Arnold played in advancing precision chronometry.

John Arnold rapidly established a reputation for outstanding mechanical expertise and was the first watchmaker to produce a jewelled ruby cylinder escapement. He showcased this in an exceptionally small half-quarter repeating watch mounted in a ring, which he offered to King George III. His growing fame attracted an affluent clientele.

He could easily have lived comfortably, making exquisite repeating watches and calendar watches. But John Arnold was relentlessly driven by the greatest watchmaking challenge of his age: to build a timepiece that would enable ships to navigate safely, transform science and roll back the boundaries in astronomy. That challenge was precision, and Arnold made it his passion.

Between 1770 and 1790, he painstakingly refined the art of watchmaking, introducing decisive improvements that heralded the arrival of chronometry. It is to him we owe a series of trailblazing inventions that included a detent escapement, a helical balance spring, terminal curves that make the helical balance spring isochronous, the firstever use of gold for balance springs, and a range of bimetallic balances that offset errors caused by temperature fluctuations.

Arnold’s chronometers were used by some of the greatest explorers and navigators of his time on their epic voyages. His regulators and their continual refinement bear witness to the colossal progress of science and astronomy across Europe.

Arnold was also heir to a series of exceptional English watchmakers, each of whom advanced the art of watchmaking in his own way: George Graham, Thomas Tompion, Thomas Mudge and John Harrison. Arnold, however, was the first to usher watchmaking into the modern era by designing high-precision, reliable watches that were also relatively easy to manufacture.

Arnold & Son Instrument Collection Métiers d’Art TB Dragon Limited Edition

The latest addition to the Arnold & Son Instrument Collection combines the marine precision of the true-beat (TB) movement with aesthetic perfection.

Featuring one of the instantly recognizable design cues of the Instrument Collection, the off-centre positioning of the time display at 9 o’clock leaves a generous open area and creates a perfect setting for the exquisite engraved and hand-painted depiction of a dragon. To underline its exclusivity, this fabulous example of high-precision technology and aesthetic perfection is available in a limited edition of just twenty-eight pieces.

Arnold and Son Instrument Collection Métiers d’Art TB Dragon Limited Edition watch

The model comprising the Métiers d’Art TB Dragon Limited Edition from Arnold & Son was created to celebrate the most divine creature In Chinese mythology. The dominant feature of this fine-quality wristwatch is a hand-engraved appliqué of a dragon executed by Arnold & Son’s master engraver, which is then duplicated for the series.

Hand engraving is a traditional art form that makes use of hardened steel tools called burins and other special implements. They create cuts, lines and texturing that build up entire images or, as in the case of the TB Dragon, a perfectly sculpted figure of a dragon in solid 22-karat rose gold.

The breathtaking richness of detail is then duplicated in rose gold for the rest of the series. Once the appliqué is in place on the dial, the dragon’s textures and shades are emphasized by hand-painting, a process that accentuates its three-dimensional nature. Hand engraving and miniature painting both call for infinite patience and expertise and take many years of concentrated practice to fully master.

Arnold and Son Instrument Collection Métiers d’Art TB Dragon Limited Edition watch

With its pure, timeless design, the Instrument Collection takes its inspiration from the chronometers produced by John Arnold’s son, John Roger, in the latter part of his career.

These were specially designed to withstand the rigours of life on the high seas and to deliver the true-beat, down to-the-second precision needed by marine navigators to determine longitude. The true beat is a rare complication these days, and combining it with an automatic winding system calls for enormous technical expertise.

Arnold and Son Calibre A&S6103 self-winding movement

In the A&S6103, this was made possible by a patented system comprising a sophisticated double wheel, an oscillating pinion and a pallet mechanism. A solution of this complexity calls for microscopic precision (to tolerances of a micron, or one thousandth of a millimetre), and the key components are made using state-of-the-art LIGA manufacturing technology.

The case houses the rhodium-treated A&S6103 movement with Haute Horlogerie finishing. All the plates and bridges in the movement are hand-chamfered and decorated – a further indication of the traditional craftsmanship upheld by Arnold & Son.

The TB Dragon special edition is limited to just twenty-eight timepieces.
