Arnold & Son Perpetual Moon “Year of the Rabbit”

Swiss luxury watch brand Arnold & Son marks the year of the Water Rabbit with a new artistic version of its elegant Perpetual Moon model.

Limited to eight timepieces, the Arnold & Son Perpetual Moon “Year of the Rabbit” timepiece features a sculpted golden rabbit set against a backdrop of black aventurine, posing next to a pagoda surrounded by waterfalls.

Arnold & Son Perpetual Moon “Year of the Rabbit”

The black aventurine glass dial accommodates a large moon-phase display. In a large aperture, a turning disc reveals the waxing and waning of the night’s celestial body, the appearance of the crescent moon and its light. It is crafted from mother-of-pearl with painted elements in relief, all enhanced with Super-LumiNova.

The dial’s aquatic elements as well as the pagoda’s windows are also hand-painted with luminescent material. In the background, the disc bearing the star is made from deep black aventurine glass.

Arnold & Son Perpetual Moon “Year of the Rabbit”

Sculpted in three dimensions, the rabbit is crafted from 18-carat rose gold. Its expression, its pose and the details of its fur are hand-engraved and -burnished to add depth and nuance.

On a disc of black aventurine glass dotted with glittering inclusions, the foliage and pagoda decorations are hand-painted with gold powder.

Arnold & Son Perpetual Moon “Year of the Rabbit”

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

The moon phase display of this movement is so precise that it will remain accurate for 122 years before deviating from the actual lunar cycle by one day.

The Arnold & Son Perpetual Moon “Year of the Rabbit” model comes with a glistening black alligator leather strap featuring visible platinum stitching. It is lined with red alligator leather in a nod to the lucky colour of Chinese symbolism.

Arnold & Son Nebula 41.5 Gold & Nebula 38 Gold

Created in two case dimensions, these new Arnold & Son Nebula watch models introduce a new colour combination, alternating between grey NAC and 5N red gold, serving to further highlight the striking structure of their skeletonised calibre.

The Nebula case is available in two diameters – 41.5 mm or 38 mm – and is remarkably slim, measuring just 8.73 mm thick. It is crafted from a block of 5N red gold for a limited edition of 88 pieces.

Arnold & Son Nebula 41.5 Gold

Arranged in a star around the edge of the calibre, the openworked, chamfered and satin-finished bridges create the impression of a watchmaking explosion, as well as a sense of rhythm and control. Positioned at regular intervals, these bridges are identical in shape but different in size and reflect the aesthetic heritage of John Arnold’s chronometers. They also illustrate Arnold & Son’s ‘Manufacture’ expertise.

Arnold & Son Nebula 41.5 Gold

A watch inspired by the stars, Nebula combines contrasting shades of gold and anthracite grey. The grey is created by a NAC treatment. When applied to the skeletonised main plate, the barrels and the flange, Nebula highlights the relief of its A&S5201 movement. Its construction is clearly legible on various levels, with the bridges in the foreground, the gear train and barrels on the second level, and the main plate behind them.

Arnold & Son Nebula 41.5 Gold

The A&S5201 calibre is visible through the sapphire crystal case-back. Two large arcs, also treated with NAC, intersect to reveal a second graphic structure, that of the main plate.

Arnold & Son Nebula 41.5 Gold movement

The highly open-worked movement is chamfered and its surface is covered with a signature Arnold & Son pattern known as ‘Rayons de la Gloire’.

Arnold & Son Nebula Gold watch movement

Like all the movements used by Arnold & Son, the A&S5201 calibre has been entirely developed, manufactured, decorated, assembled, adjusted and cased-up at the Manufacture in La Chaux-de-Fonds. This calibre draws on a pair of large barrels and an oscillating frequency of 3 Hz, which delivers a 90-hour power reserve.

Arnold & Son x Matt Copson Edition, Unique Piece for TimeForArt Auction

Swiss watchmaker Arnold & Son has commissioned British artist Matt Copson to create a unique timepiece for auction: the Arnold & Son x Matt Copson edition. The one-of-a-kind timepiece will feature in the Swiss Institute’s TimeForArt auction, a subset of the upcoming Phillips New York Watch Auction: SEVEN, coming to New York this December.

Arnold & Son commissioned Copson in tribute to the Swiss watchmaker’s longstanding British ties, and together, the creative partners designed a luminous spider web inspired watch for the first-ever benefit watch auction in support of contemporary art.

Arnold & Son x Matt Copson Edition, Unique Piece for TimeForArt Auction

The inaugural edition of TimeForArt curates exceptional timepieces from the world’s foremost watchmakers, including the Arnold & Son x Matt Copson collaboration, with 100% of the proceeds going directly to supporting today’s most visionary artists through Swiss Institute’s innovative exhibitions, public programs, educational and community engagement workshops in New York and beyond.

Each curated TimeForArt timepiece expresses the most artistic elements of contemporary watchmaking, shining a light on the creative core at the heart of horology today.

Arnold & Son x Matt Copson Edition, Unique Piece for TimeForArt Auction

Featured watches, including the Arnold & Son HM SI Matt Copson edition, were developed in alignment with the theme “artists for artists,” and represent unique collaborations with world-renowned artisans, interventions by leading contemporary artists, bespoke examples of innovative craftsmanship, or coveted limited-edition timepieces.

Arnold & Son offered the renowned artist carte blanche to create the design of his choice. With the dial as his canvas, Copson opted for a spider web motif and employed a polished silver tone web in relief against a matte silver background. A spider caps the hour hand and a fly the minute hand, so that once every hour the spider appears to catch the fly, yet every hour it escapes again. The seemingly playful touch and cartoonish element of the dial aligns with Copson’s larger body of work, which explores deeper themes of life, death, and pursuit of purpose.

In darkness, the dial comes alive with dramatic green SuperLuminova – an allusion to the artist’s frequent use of light and lasers. The spider and fly also received a luminous treatment.

In the fall of 2022, the collection, including the Arnold & Son SI HM Matt Copson unique watch, will be showcased globally at a series of events held in partnership with Phillips.

Arnold & Son x Matt Copson Edition, Unique Piece for TimeForArt Auction

The lots will be offered by live auction, in partnership with Phillips in Association with Bacs &Russo, on December 10 and 11, 2022, at the Phillips New York headquarters at 432 Park Avenue. Bids may be placed in advance or during the live streamed event – in-person, via the phone, or online.

Arnold & Son Luna Magna Meteorite Limited Edition

The new Arnold & Son Luna Magna Platinum model with a spherical astronomical moon has a sand-coloured PVD-treated meteorite dial.

The part of the moon in shadow is also made from meteorite. In a final harmonious touch, Luna Magna Platinum shines with a distinctive glow at night thanks to the Super-LumiNova coating on its moon hemisphere and opal subdial.

Arnold & Son Luna Magna Meteorite Limited Edition

With a satin circular-grained finish, the hour and minute subdial is crafted from white opal, a semiprecious gemstone known for its purity and delicacy and befitting of Luna Magna’s complication. The off-centred position of this display frees up the dial, which is adorned with a large sand-coloured meteorite disc.

Arnold & Son Luna Magna Meteorite Limited Edition

At 6 o’clock, the three-dimensional moon is carved from the same meteorite and Cacholong opal whose properties lend it to sculpting. Lastly, the understated shine of the platinum case establishes the distinguished elegance of this limited edition of 28 pieces.

Arnold & Son Luna Magna Meteorite Limited Edition

Arnold & Son chose a meteorite from the octahedrite class that, once worked, reveals “Widmanstätten patterns”, which are instantly recognisable for their jagged criss-crossing structures. The PVD treatment in a grey-beige shade reminiscent of stardust brings out the striking geometric motifs, creating a sense of harmony with Luna Magna’s astronomical complication.

Arnold & Son Luna Magna Meteorite Limited Edition

The various materials catch the light and give this timepiece multiple different faces. The cool shine of the platinum is tempered by the iridescence of the meteorite and the milky whiteness of the various opals. Arnold & Son selected these stones both for their moon-like porcelain hue and their properties which make it possible to add Super-LumiNova – invisible by day but glowing blue-green at night.

Arnold & Son Luna Magna Meteorite Limited Edition lume

Luna Magna Platinum is driven by the A&S1021 calibre, which has been fully developed, manufactured, assembled and adjusted in the Arnold & Son Manufacture.

Arnold & Son Luna Magna Meteorite watch movement

This 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 includes a secondary display detailing the age of the moon on the case-back side.

Arnold & Son Luna Magna Meteorite watch case-back The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. The Manufacture 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.

Arnold & Son Luna Magna Ultimate II Limited Edition

Arnold & Son has released a new high-jewellery version of its three-dimensional moon model.

A limited edition of eight pieces, the Arnold & Son Luna Magna Ultimate II watch entices the eyes with its unique alliance of baguette-cut diamonds, Paraíba tourmaline and PVD-treated ruthenium crystals.

The 44 mm diameter case is crafted from 18K white gold and is studded with no fewer than 7.62 ct of exceptional-quality diamonds.

Arnold & Son Luna Magna Ultimate II Limited Edition

The extraordinary colour of the Paraíba tourmaline is the finishing touch on this exotic and refined piece in blue-green tones bordering on turquoise. The bezel and the lugs of Luna Magna Ultimate II are adorned with 112 invisible-set baguette-cut diamonds totalling 5.90 ct.

The glittering appearance of the dial is due to millions of pure ruthenium crystals. This extremely hard metal is much rarer than platinum. For Luna Magna Ultimate II, the ruthenium was reformed into crystals and dyed using complex processes, before being deposited onto a dial plate.

Arnold & Son Luna Magna Ultimate II Limited Edition

A traditional dial is located at 12 o’clock, marked with 12 signature Arnold & Son Roman numerals. This off-centre subdial owes its pristine, slight milky white hue to opal.

Its classic design harks back to the aesthetics of the famous marine chronometers made by English watchmaker John Arnold. Under the time display, Luna Magna’s three-dimensional moon takes on a new appearance.

Arnold & Son Luna Magna Ultimate II Limited Edition

The white gold globe is entirely pavé-set. It is split into 161 brilliant-cut diamonds, representing the illuminated side of the moon, and the same number of Paraíba tourmalines for the portion in shadow.

Luna Magna Ultimate II is driven by the A&S1021 calibre, which has been fully developed, manufactured, assembled and adjusted in the Manufacture. This 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.

Arnold & Son Luna Magna Ultimate II Limited Edition

The movement offers a secondary display on the case-back side presenting the phase of the moon. Its clearly readable markings are designed for high-precision adjustments.

The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds, and 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 make, as the Luna Magna’s moon-phase function is directly accessible from the crown.

Arnold & Son Perpetual Moon 41.5 Red Gold & Platinum Models

Arnold & Son’s Perpetual Moon watch is now available in two new interpretations in 41.5mm diameter case, in red gold or platinum. Its dial features a unique motif, Stellar Rays.

Perpetual Moon 41.5 Red Gold joins the permanent collection, while the platinum version is produced in a limited edition of 28 timepieces.

Arnold & Son Perpetual Moon 41.5 Red Gold

The Perpetual Moon 41.5’s cases in 18-carat (5N) red gold or 950 platinum have been redesigned. The lugs have been simplified so that instead of their original cross shape, they now present a tauter form of plunging bars with bevelled ends.

Arnold & Son Perpetual Moon 41.5 Platinum

The case, previously measuring 42 mm, is reduced to 41.5 mm without affecting the size of the dial. This has reduced the width of the bezel, drawing attention to the dial, its finishes, and its vast moon.

Arnold & Son Perpetual Moon 41.5 Platinum

 

The dials on these new creations present a unique finish known as Stellar Rays, its aesthetic obtained through skilfully irregular engraving. Several depths and widths of rays coexist and follow on from one another, creating their own rhythm, each generating a fluctuating interplay of light and a depth obtained by applying several layers of transparent lacquer.

Arnold & Son Perpetual Moon 41.5 Red Gold

This unique effect is employed in two forms. Perpetual Moon 41.5 Red Gold is combined with a dense, deep blue adorned with gold edging on the moon aperture, together with golden hands and hour markers. Perpetual Moon 41.5 Platinum is coupled with a salmon pink whose soft metallic radiance complements the rhodium-plated details on the dial.

Arnold & Son Perpetual Moon 41.5 Red Gold

Realistically depicted with hand-painted shadows, the large moon is enhanced with a luminescent material that is particularly intense in darkness yet invisible in daylight, giving way to the white mother-of-pearl disc. It is set against a blue PVD-treated grained sky and is surrounded by the constellations of the Big Dipper and Cassiopeia, also hand-painted and coated with Super-LumiNova.

Arnold & Son Perpetual Moon 41.5 Red Gold

The constellations have been chosen as a direct reference to John Arnold’s history as a maker of naval chronometers.

The Big Dipper and Cassiopeia have been used by navigators in the northern hemisphere since time immemorial to find their bearings and locate the North Star (Polaris). The position of the latter defines the North and its angular altitude, or position in the North-South plane, and allows the distance to the equator, i.e., latitude, to be estimated.

Arnold & Son Perpetual Moon 41.5 Platinum

On the case back, a secondary indicator allows the moon phase to be adjusted quickly and precisely. The hand-wound calibre that powers it, reference A&S1512, can track the development of its segments with exceptional precision.

Arnold & Son Perpetual Moon 41.5 Red Gold

The duration of a complete lunar cycle is 29 days, 12 hours, 44 minutes and 2.8 seconds. Arnold & Son has succeeded in representing it in such a way that it would take 122 years for this movement, if regularly wound, to accumulate a day’s difference between its display and celestial reality.

Arnold & Son Perpetual Moon 41.5 Platinum

Like all Arnold & Son movements, the A&S1512 calibre has been entirely developed, manufactured, decorated, assembled, adjusted and cased at the Manufacture in La Chaux-de-Fonds. The calibre features two barrels and an oscillation frequency of 3 Hz, providing a power reserve of 90 hours.

Arnold & Son Ultrathin Tourbillon New Red Gold & Platinum Models

Arnold & Son has released two new iterations of its ultrathin tourbillon watches. These new watches feature a new type of dial with tinted gold and aluminium sparkles to match their precious cases, which have also been redesigned.

In 5N red gold or 950 platinum, the cases are just 8.3 mm thick beneath their domed sapphire crystals. The offset display and the tourbillon aperture echo the way in which information was arranged on John Arnold’s marine chronometers.

Arnold & Son Ultrathin Tourbillon Red gold

To give the Ultrathin Tourbillon a new unique and refined design, Arnold & Son has focused on materials and techniques that highlight the precious appearance of this finely honed tourbillon.

Arnold & Son Ultrathin Tourbillon Platinum

The 41.5 mm cases in 5N red gold or 950 platinum have been redesigned, making them even slimmer and more refined. The bezels have been reduced to a fine metal band, the sapphire crystals are domed, and the transparent case backs have been screwed down.

Arnold & Son has used a new manufacturing technique known as ‘Cosmic Grené’ on the dials. This name makes direct reference to stargazing, as stars are essential guides for navigating at sea along with marine chronometers.

Arnold & Son Ultrathin Tourbillon Red gold

Gold powder mixed with aluminium sparkles has been placed on the dial plate to create a lightly sandblasted surface. This is then coloured: blue for the Ultrathin Tourbillon in red gold, and green for the platinum version. Due to the complex manufacturing methods involved, these dials are subtle and finely textured, with a discreet lustre.

Arnold & Son Ultrathin Tourbillon Platinum

The Arnold & Son Ultrathin Tourbillon watch houses the A&S8300 calibre, whose architecture and finesse characterise this collection. At just 2.97 mm thick, it is one of the slimmest tourbillon movements ever designed.

The tourbillon carriage has also been redesigned and undergone significant changes in relation to its predecessors. It features a variable-inertia balance with inertia blocks to ensure more stable calibration over time.

Arnold & Son Ultrathin Tourbillon Red gold

The redesigned tourbillon carriage echoes the leading role John Arnold played in marine exploration during the 18th century. Its triangular shape evokes a sextant, while its double-arrow counterpoise represents an anchor. The point in the middle serves as a seconds marker, as the carriage completes a full rotation in one minute.

Arnold & Son Ultrathin Tourbillon Platinum

The back of the Ultrathin Tourbillon reveals a new rear tourbillon bridge in 3N yellow gold that matches the gear train and stands out from the appearance of the rest of the calibre.

Modifications to the tourbillon carriage and regulating organ have increased the power reserve of the A&S8300 calibre, which now lasts at least 100 hours.

Arnold & Son Perpetual Moon 38 Red Gold Moonlight

Arnold & Son is expanding its moon-phase collection with the new Perpetual Moon 38 model in red gold (5N) featuring a shimmering blue mother-of-pearl dial.

The Arnold & Son Perpetual Moon 38 Gold Moonlight watch is adorned with 138 diamonds for a total of ~2.61 carats. This timepiece is powered by a finely crafted manual-winding calibre.

Arnold & Son Perpetual Moon 38 Gold Moonlight

Under the delicately blue-tinged mother-of-pearl dial with an open-worked upper section, a large sky disc, also in mother-of-pearl, bears a white moon adorned with Super-LumiNova and hand-painted shadows. Nearby, the Ursa Major and Cassiopeia constellations complete the scene.

Arnold & Son Perpetual Moon 38 Gold Moonlight watch

Perpetual Moon 38 Gold thus presents two faces. The first is the gem-set gold case and its mother-of-pearl dial evoking daytime. The other glows with a cold blue light to represent the night, when the stars painted with luminescent material shine and when the moonlight truly comes into its own.

Arnold & Son Perpetual Moon 38 Gold Moonlight

For the Perpetual Moon 38 Gold watch, Arnold & Son has created an entirely new women’s calibre, the smallest in its collection.

At 29.4 mm, the A&S1612 movement was designed to fit the new 38 mm diameter case that is just 10.44 mm thick. This manually wound movement has a power reserve of 90 hours.

Arnold & Son Perpetual Moon 38 Gold Moonlight

Arnold & Son draws on its iconic complication by presenting a large moon disc on this A&S1612 calibre. The various crescents displayed between 10 o’clock and 2 o’clock faithfully recreate the appearance of the Earth’s satellite. This moon-phase complication will remain accurate for 122 years.

Arnold & Son Nebula 41.5 Steel

The new Nebula 41.5 Steel watch by Arnold & Son boasts a magnificent skeleton movement enhanced with grey and blue tones. Measuring just 8.73 mm thickness, this ultra-thin steel watch with blue PVD treated flange and movement parts offers a perfectly chic visual effect. It is the most symmetrical of Arnold & Son’s watches.

Arnold & Son Nebula 41.5 Steel

Inspired by the distinct body of interstellar clouds of same name, the Nebula watch boasts seven bridges on the dial side. Radiating from the centre outwards, these structures give the impression of a cosmic explosion.

Arnold & Son Nebula 41.5 Steel

Specially created for this Nebula watch, the A&S5201 movement is set apart by its skeletonisation and almost perfect symmetry. The traditional shape of its bridges is inspired by John Arnold’s chronometers and their open-worked structure accentuates the feeling of lightness in a very mechanistic design.

Arnold & Son Nebula 41.5 Steel

The bridges of the A&S5201 calibre are palladium-treated, giving a sheen that echoes the steel case. The mainplate, barrel covers, and dial flange have been coloured with a blue PVD treatment. The two-tone aesthetic adorns the interior and exterior, the substance of the watch and the details.

Arnold & Son Nebula 41.5 Steel

The A&S5201 calibre was conceived as a skeleton mechanism instead of being modified by removing material. The result is a completely clear and legible display on both sides. One by one, the components reveal their subtle finishes, adopting strict, fluid forms. At 4 mm thick, the calibre contributes to the piece’s overall slimness.

Arnold & Son Nebula 41.5 Steel watch

The A&S5201 calibre has also undergone several developments in addition to the new blue colouring. The balance wheel is now rhodium-plated to match the gear train and perfectly coordinate with the small seconds placed opposite.

Arnold & Son Nebula 41.5 Steel

The mainplate, particularly its reverse side, features “Rayons de la Gloire” finishes, a surface treatment similar to sunray-brushing in a wave shape. Once fully wound, the movement offers a total power reserve of 90 hours.

Arnold & Son Nebula 41.5 Steel

The Nebula 41.5 Steel is fitted with either a three-link steel bracelet or a ballistic-type rubber strap with a woven-look surface.

Arnold & Son Perpetual Moon 38 Eclipse I Limited Edition

Dressed in a sparkling gem-set white-gold case measuring 38 mm diameter, the Perpetual Moon 38 Eclipse I watch ushers in a new chapter for women at Arnold & Son. Its bezel, four horns and crown host a total of 90 brilliant-cut diamonds.

Arnold & Son Perpetual Moon 38 Eclipse I Limited Edition

The dial of the Arnold & Son Perpetual Moon 38 Eclipse I watch is composed of a fine layer of blue aventurine crystal, featuring lace-like cut-outs through which the large moon disc can be glimpsed. The starry sky is made of mother-of-pearl in a graduation of shades from blue to white. The two lunar discs are depicted by ruthenium crystals. Between them, the constellations have been painted by hand.

Arnold & Son Perpetual Moon 38 Eclipse I Limited Edition

At 8 o’clock, the main motif of the Perpetual Moon 38 Eclipse I scintillates with precious stones. The cut-outs adorning the lace-like aventurine backdrop have been encrusted with white and blue mother-of-pearl fragments, diamonds, and blue and pink sapphires, all cut to form a large star complete with glistening halo.

Arnold & Son Perpetual Moon 38 Eclipse I Limited Edition

For the Perpetual Moon 38 Eclipse I, Arnold & Son has created an entirely new calibre, which is also the smallest in its collection. At 30 mm, the A&S1612 calibre was designed to fit the new 38 mm diameter case that is just 10.44 mm thick. This manually wound movement is endowed with an autonomy of 90 hours.

The moonphase display has an accuracy of 122 years. The various crescents of the ingenious large-moon fill the large aperture located between 10 and 2 o’clock.

Arnold & Son Year of the Tiger Perpetual Moon Limited Edition

To celebrate the start of the New Year in the traditional Chinese astrological calendar, Arnold & Son is releasing a limited edition comprising eight pieces of its high-precision phases of the moon model. The “Year of the Tiger” Perpetual Moon features a sculpted golden tiger against a backdrop in specular hematite, a rare and expressive stone.

The Year of the Tiger starts on Tuesday 1 February 2022. The tiger’s courage and power are tempered by the element of water. The animal featured on the dial of the “Year of the Tiger” Perpetual Moon is therefore standing on a riverbank.

Arnold & Son Year of the Tiger Perpetual Moon Limited Edition

On the canvas offered by the dial of this exceptional piece, Arnold & Son has accommodated a large moon. In a wide window a turning disc reveals the waxing and waning of the celestial body, the appearance of the crescent moon and its light. This moon is crafted from mother-of-pearl enhanced with Super-LumiNova, and its relief is painted.

In daylight it is grey, almost white. In the dark it lights up from the interior and takes on a new aspect, brimming with gleaming detail. This is complemented by all the aquatic details on the dial, also hand-painted with luminous pigments. In the background, the disc bearing the star is made from a deep black aventurine glass.

Arnold & Son Year of the Tiger Perpetual Moon Limited Edition watch 2022

The centrepiece of this dial is, however, the tiger itself. Sculptured in three dimensions, it is crafted from 18-carat rose gold. Its expression, its pose and the details of its fur are hand-engraved and -burnished. This meticulous, high-calibre work is a testimony to Arnold & Son’s exceptional attention to detail in their limited editions paying tribute to the Chinese zodiac.

Arnold & Son Year of the Tiger watch

The same holds true for the dial. A decoration depicting bamboo is painted in gold powder on the hematite disc with glittering inclusions. To round off this dazzling scene, the “Year of the Tiger” Perpetual Moon is mounted on a glistening black alligator strap backed with red alligator leather and stitched with platinum thread.

Arnold & Son Year of the Tiger Perpetual Moon Limited Edition

Like all the movements used by Arnold & Son, the A&S1512 calibre was entirely developed, produced, decorated, assembled, adjusted and cased up between the walls of the brand’s manufacture in La Chaux-de-Fonds. This calibre is based on two barrels 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.

Arnold & Son Double Tourbillon Jade

Arnold & Son is celebrating its Double Tourbillon collection with the unveiling of two unique pieces adorned with dazzling green jade and delicate white opal. The two independent tourbillons and two time zones of this rare model have taken on a new face.

The new Double Tourbillon Jade models are available in either red gold or white gold. The green jade dial is punctuated by two opal sub dials in immaculate white. The A&S8513 calibre allows its two independent tourbillons to emerge into view above these rare stones. United by a shared main plate, each displays a different time zone.

Arnold & Son Double Tourbillon Jade

Sourced from Wyoming, the bright green nephrite (jade) known as “Apple Green” is slightly veined with black. This brings greater depth, contrast and makes the stone all the more precious.

The dial plate of the Double Tourbillon Jade has been expertly cut in a very particular way. In the shape of a clover, the main plate allows both dials and tourbillons to emerge to their full height. This complicates the stone cutting and engraving stages, which further underlines the mastery of the work.

Arnold & Son Double Tourbillon Jade

The Double Tourbillon Jade movement is integrated into a red gold or white gold case with a diameter of 43.5 mm. Its sapphire crystal is domed, accommodating the height created by the two tourbillons. These are attached to a three-dimensional, skeletonized, cantilevered bridge, and are made in the same gold as the case.

Arnold & Son Double Tourbillon Jade

Paying homage to its founder, John Arnold, one of the most inventive watchmakers of his time and of the golden age of chronometry, Arnold & Son has always approached the double time zone with sophistication and precision. Instead of the classic “GMT” system, where an hour hand in the centre indicates the second time zone, Arnold & Son has chosen to give each time zone its own regulating organ: a reminder of the duality of time telling methods – timepieces on one hand, astronomy on the other – used on board English frigates in the 18th century.

Arnold & Son Double Tourbillon Jade

The A&S8513 calibre is therefore equipped with two barrels and two crowns that control the two time zones. At midday, the local time is visible in Roman numerals. At six o’clock, Arabic numerals indicate the time of a second, more distant place that has a connection to the wearer. The two time zones are set completely independently down to the minute. Unlike most so-called travel watches, the Double Tourbillon Jade can therefore follow time zones offset by 15, 30 or 45 minutes, as is the case with certain countries in Central Asia.

Arnold & Son Double Tourbillon Jade

The structure of the movement can be seen on the back of the Double Tourbillon Jade. From the radiant Côtes de Genève to the circular-graining on the main plate, double snailing of the barrels, sunray decoration on the crown wheels, and polish on the gold bezels held in place by blued screws, everything about the A&S8513 calibre exudes eminence, craftsmanship and excellence.

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

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

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

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.

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.

Arnold & Son Ultrathin Tourbillon Koi

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.

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.

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.

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.

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.
