Frederique Constant Highlife Emerald Limited Editions: The Highlife Emerald Tourbillon Perpetual Calendar Manufacture and the Highlife Emerald Worldtimer Manufacture

Frederique Constant has expanded its Highlife series by presenting two stunning and exclusive Highlife Emerald limited editions: the Highlife Emerald Tourbillon Perpetual Calendar Manufacture (limited to 30 pieces) and the Highlife Emerald Worldtimer Manufacture (limited to 222 pieces).

Unveiled at the Dubai Watch Week 2021, these special edition watches feature emerald green dials. A tone dear to Frederique Constant, the green colour is associated with nature, representing the source of life.

In 1999, Frederique Constant introduced the very first Highlife watches. In 2020, the Maison revived the iconic design and reintroduced the collection with resolutely modern curves rooted in the 21st century, thus adding a new dimension to the definition of accessible luxury according to Frederique Constant. The new design translates into both taut and flexible lines, the modernity of a creation that denies nothing of its craftsmanship, balance or style.

One of the key hallmarks of Highlife stamped timepieces is an integrated and interchangeable strap, offering a seamless integration with the watch case. This innovative system makes it possible to change the strap at will and without the need for tools.

Frederique Constant Highlife Emerald Worldtimer Manufacture

Dedicated to frequent travelers, the Frederique Constant Highlife Worldtimer Manufacture watch boasts a globe engraved dial, combined to a contemporary 41 mm steel case.

The highly contemporary design of the steel case and dial with globe engraving is an ode to travel. The FC-718 manufacture calibre is designed exactly for that. The self-winding mechanical movement has a power reserve of 38 hours. It is visible through the case back, water-resistant up to 50 metres. The movement incorporates typical Genevan finishes like perlage and circular Côtes de Genève.

Highly user-friendly, its single crown can be used to set any function: hours, minutes, the date at 6 o’clock and the 24 cities disc that represents 24 time zones on Earth, itself engraved in the centre of the piece. There is no day / night indicator required; the inner disc has been engraved with 12 hours on the light area (cities where it is daytime) and 12 hours on the blue area (those where it is night-time).

Green is the dominant colour of the Highlife Emerald Worldtimer Manufacture Limited Edition. It takes up the whole centre of the dial, as well as the date counter, for which Frederique Constant has used its unique sunray guilloché for improved legibility. This is skimmed by three central rhodium-plated hands, including luminescent hour and minute hands that are easy to read, even when travelling to the other side of the world at night.

The Highlife Emerald Worldtimer Manufacture is delivered with an integrated and interchangeable steel bracelet, which can be switched to an extra black rubber strap on a split second, to complement the urban feel of the watch.

Frederique Constant Highlife Emerald Tourbillon Perpetual Calendar Manufacture

Presented in a steel case, this bold timepiece incorporates two most prestigious horological mechanisms: Tourbillon and Perpetual Calendar.

Within the 41 mm case with the integrated strap characteristic of the Highlife collection, Frederique Constant has organised its complications into four segments.

The brand has arranged both day and date displays horizontally, so as to be read in a natural and intuitive way in a fraction of a second. Brought together in a single counter at 12 o’clock are the month (large hand) and leap year indication (small hand). Adding the finishing touch to this perfectly mastered aesthetic composition, the tourbillon balances it out at 6 o’clock, counting down the seconds with its central hand.

The Highlife Emerald Tourbillon Perpetual Calendar Manufacture is dominated by the green colour. On both sides of the complications on display, Frederique Constant has opted for a face without a dial. This allows you to see the inner workings of the FC-975 Manufacture calibre, alongside the delicate blued screws, perlage and subtle Côtes de Genève.

It also improves the contrast between the rhodium-plated movement and the perpetual calendar display. To ensure it is easy to read, the Manufacture has also been careful to give them recessed counters on two levels, so as to better capture the light.

The FC-975 caliber is designed, produced and assembled in very limited numbers at the Geneva-based manufacture. For greater precision (an essential characteristic of the tourbillon), Frederique Constant has equipped it with a silicone escapement – both the escape wheel and the lever.

Limited to 30 timepieces, this exclusive model is mounted on a three-link polished and satin-brushed steel bracelet, and delivered alongside a second rubber strap.

Frederique Constant Highlife Tourbillon Perpetual Calendar Manufacture Limited Edition

Frederique Constant presents a high complication watch that combines two iconic horological complications: Perpetual Calendar and Tourbillon. Belongs to the Frederique Constant Highlife collection this timepiece is available in 18 carat rose gold and stainless steel versions. The Tourbillon Perpetual Calendar watch is equipped with the FC-975 Manufacture self-winding movement.

Within the 41 mm case with the integrated strap characteristic of the Highlife collection, Frederique Constant has organised its complications into four segments.

The brand has arranged the day and date counters horizontally so that they can be read in a natural and intuitive way in a fraction of a second.

Brought together in a single counter at 12 o’clock are the month (large hand) and leap year indication (small hand). Adding the finishing touch to this perfectly mastered aesthetic composition, the tourbillon balances it out at 6 o’clock, counting down the seconds with its central hand.

The FC-975 calibre is designed, produced and assembled in very limited numbers at the Geneva-based manufacture. For greater precision, Frederique Constant has equipped it with a silicone escapement – both the escape wheel and the lever.

The inner workings of this exceptional movement can be admired from any angle on the Highlife Tourbillon Perpetual Calendar Manufacture, on the dial side and on the back. Correctors used to set the watch are discreetly tucked away in the caseband.

The two versions are dominated by the colour blue. On both sides of the complications on display, Frederique Constant has opted for a face without a dial. This allows you to see the inner workings of the FC-975 Manufacture calibre, alongside the delicate blued screws, perlage and subtle Côtes de Genève.

It also improves the contrast between the rhodium-plated movement and the perpetual calendar display. To ensure it is easy to read, the Manufacture has also been careful to give them recessed counters on two levels, so as to better capture the light.

Although the Highlife Tourbillon Perpetual Calendar Manufacture is strictly limited to 30 pieces for the rose gold version and 88 for the steel version, collectors can create different looks for their numbered and engraved watches. Each one comes with two straps, which can be swapped around at will, without the need for tools.

The rose gold version comes with a topstitched alligator leather strap, alongside a second rubber strap, reinforcing the urban and contemporary attitude that the Highlife Tourbillon Perpetual Calendar Manufacture can take on in seconds.

This same rubber strap also comes with the steel watch, alongside a steel strap with a three-link design comprised of polished and satin-brushed links and a folding buckle bearing the Frederique Constant hallmark.

Vacheron Constantin Les Cabinotiers Armillary Tourbillon Perpetual Calendar – Planetaria

Unveiled at the digital Watches and Wonders event in April 2021 by Vacheron Constantin, the Les Cabinotiers Armillary Tourbillon Perpetual Calendar – Planetaria is a single-piece edition timepiece with a retrograde jumping perpetual calendar regulated by a double-axis tourbillon and complemented by a three-dimensional representation of the two hemispheres designed to provide 24-hour and day/night indications.

Equipped with a new Calibre 1991 in-house movement, this timepiece celebrates the astronomical function par excellence: the perpetual calendar with precision moon phases. With its retrograde date appearing along a right-hand arc on the dial, as well as its circular retrograde month and day indications framing depictions of the Earth’s two hemispheres providing day/night indications, this timepiece is also regulated by a double-axis tourbillon.

Extraordinarily complex with its 745 components, mechanical manual-winding Calibre 1991 is the result of a four-year development process. It powers two rotating globes representing the Earth’s hemispheres, regulated by a double-axis armillary tourbillon. It corresponds to an innovative interpretation of the perpetual calendar, the astronomical complication par excellence which “reads off” the specificities of the calendar without requiring any adjustments before 2100.

Another distinctive feature lies in the retrograde displays of the perpetual calendar’s days, dates and months. Mounted on ball bearings to ensure smooth, linear operation, the date display follows a circular arc to the right of the hours and minutes dial.

In keeping with the watch’s astronomical vocation, the centre of the timekeeping dial bearing hour-markers is dedicated to the moon phases. These appear according to their respective evolution in the two hemispheres, in perfect symmetry with the two rotating globes, and with a degree of precision requiring a mere one-day correction every 122 years.

The perpetual calendar functions continue with the leap year appearing through a 5 o’clock aperture, along with circular day and month indications at 12 o’clock and 6 o’clock based on a jumping retrograde pallet-type display system.

In the centre of the two counters, the two globes representing the Northern and Southern hemispheres perform complete rotations in opposite directions on a graduated 24-hour scale around the rim. The shaded areas of the domed sapphire crystal used for the day/night indication have been positioned in such a way that the armillary tourbillon resembles a sun darting its rays across the surface of the Earth.

Making the super-thin (0.35 mm) sapphire crystal featuring the domes and extending over the retrograde date display required a great deal of ingenuity. A crown-integrated pusher enables simultaneous adjustment of the world-time function of the two globes.

In an additional challenge for the movement’s designers, who are consistently concerned with achieving optimal balance and aesthetic appeal, they had to imagine and design a retrograde system for the day and month indications leaving sufficiently ample space to admire the beating of the bi-axial armillary tourbillon with its spherical balance-spring.

The complex mechanics of Calibre 1991 are perfectly epitomised in its armillary tourbillon, a technical challenge as well as a spectacular sight in itself. This movement regulating device endowed with a 60-hour power reserve benefited from the research conducted on the world’s most complicated timepiece, Reference 57260.

This construction is positioned on the left side of the piece, beneath the sapphire crystal ‘bubble’. Forming a sphere in perpetual motion, the tourbillon was named “armillary” in reference to French watchmaker Antide Janvier, who towards the end of the 18th century invented a moving planetary sphere known as an armillary, and regarded as one of his most accomplished masterpieces.

Another technical feature of the mechanism of this piece is the cylindrical balance-spring coupled with the balance. Invented by Jacques-Frédéric Houriet in 1814, this variant devoid of terminal curves gives the tourbillon a perfectly concentric beat, thereby ensuring enhanced isochronism.

In order to transmit to this balance-spring the impulses corresponding to a frequency of 18,000 vibrations per hour (2.5 Hz), Vacheron Constantin has developed an escapement consisting of a silicon escape-wheel and a lever with diamond pallets, materials reducing friction without any need for lubrication and thus increasing the precision of the mechanism.

Every single detail of the finishes gracing this single-piece edition highlights this ingenious astronomical orchestration of time. Two galvanically treated titanium globes weighing barely 0.12 grams rotate gently on the finely grained dial.

The 24-hour counters surrounding them are circular satin-finished with transfers, while the day, month and date indications are printed beneath the sapphire crystal.

The timekeeping dial features Roman numerals in the form of polished gold appliques. These Haute Horlogerie finishes are beautifully framed by an 18K 5N pink gold case measuring 46 mm in diameter and fitted with an alligator leather strap.

In the Vacheron Constantin universe, Les Cabinotiers represents a department in its own right dedicated to the personalisation of Grand Complication models and single-piece editions. Each year, the Les Cabinotiers department unveils a range of single-piece editions relating to a theme cherished by Vacheron Constantin. The year 2021 is dedicated to “Le Temps Céleste” (which means Celestial Time), with timepieces referring to the astronomical origins of time measurement.

IWC Schaffhausen Portugieser Perpetual Calendar Tourbillon (Ref. 5045)

The newly released IWC Schaffhausen Portugieser Perpetual Calendar Tourbillon (Ref. 5045) brings together the two complications that give the watch its name. Two References are available, both limited to 50 each. One will be available as a Boutique Edition with an 18-carat Armor Gold® case, while the second will be available in platinum.

IWC Schaffhausen Portugieser Perpetual Calendar Tourbillon, Ref. IW504504 Boutique Edition: 18-carat Armor Gold® case, blue dial, gold-plated hands, 18-carat gold appliques, blue alligator leather strap by Santoni.
IWC Schaffhausen Portugieser Perpetual Calendar Tourbillon, Ref. IW504505: Platinum case, silver-plated dial, rhodium-plated hands and appliques, blue alligator leather strap by Santoni.

The IWC-manufactured 51950 calibre combines a perpetual calendar with a tourbillon that has 82 individual parts and weighs only 0.635 grams. To make it visible at 12 o’clock, the calendar module’s advance ring was opened, and the moon phase integrated into the month display at 6 o’clock.

With its 18-carat gold rotor, the automatic winding system builds up a large, seven-day power reserve. The perpetual calendar’s mechanical programme automatically recognises the different lengths of the months and adds an extra day at the end of February every four years. The moon phase display is so precise that it will need adjusting by one day after 577.5 years.

Chopard L.U.C Perpetual T Spirit of the Dragon and the Pearl

Leave a comment

This one-of-a-kind horological masterpiece showcases the high level expertise of Chopard’s Mains d’art. The L.U.C Perpetual T Spirit of the Dragon and the Pearl watch proudly features dragon engravings inspired by China’s founding myths are shown to stunning effect on the hand-engraved case middle.

Tales of Ancient China almost inevitably evoke the dragon, a central animal in the founding myths of the Celestial Empire’s first dynasties. They tell of the fabled five-clawed dragons serving the emperor in the quest for the sacred pearl leading to wisdom and knowledge.

It is precisely this legendary vision of China that Chopard has decided to express through its L.U.C Perpetual T Spirit of the Dragon and the Pearl timepiece, a one-of-a-kind model which, like a sacred pearl, ushers the observer into a world of emotions.

The task of engraving the 18-carat rose gold was entrusted to the Mains d’art of the Maison. This exquisitely refined figurative work has been crafted using the fine line engraving technique so as to highlight two dragons on the case middle and space between the lugs, chasing after the sacred pearl depicted on the crown. More specifically, this allegory represents two Tian Long dragons, creatures of the sky and symbols of the soul’s elevation to a state of pure consciousness.

To complete the scenography, the solid gold dial of the L.U.C Perpetual T Spirit of the Dragon and the Pearl is adorned with an engraved motif drawn from traditional Chinese iconography, like those appearing on the rose gold bezel and buckle. The scrolling patterns of the watch case are thus matched by the pleasing geometry of its face.

This model with its L.U.C 02.15-L movement and featuring two stellar horological complications is no exception to these abiding principles of excellence. The 353-part movement of the L.U.C Perpetual T Spirit of the Dragon and the Pearl is equipped with a tourbillon regulator whose carriage, carrying the small seconds indicator, rotates once a minute beneath its polished steel bridge at 6 o’clock.

Complementing the display is a perpetual calendar requiring no correction until the year 2100, since only century years divisible by 400 are leap years, making 2100 a common year. To ensure perfect readability of the calendar indications, they are spread over two dials – one at 3 o’clock for the month and leap years and another at 9 o’clock for the day and the 24-hour indication – along with a large twin-aperture date rounding off the symmetry of the dial at 12 o’clock.

Thanks to its tourbillon calibre, a prestigious early 19th century watchmaking invention designed to compensate for the effects of gravity on watch mechanisms, the L.U.C Perpetual T Spirit of the Dragon and the Pearl timepiece is well-equipped to achieve a high degree of precision: a requirement laid down by Karl-Friedrich Scheufele, co-president of Chopard, who insists that all L.U.C watches from the Manufacture be certified by the Swiss Official Chronometer Testing Institute (COSC).

This is what makes it possible to place the title of “Chronometer” on the dial of the L.U.C Perpetual T Spirit of the Dragon and the Pearl, in addition to the ‘Poinçon de Genève’ quality hallmark stamped on the back, one of the most demanding watch industry labels.

To ensure optimal user friendliness, the watch is also equipped with Chopard Quattro technology, based on four series-coupled barrels ensuring a nine-day power reserve indicated on the back of the watch.

A. Lange & Söhne Datograph Perpetual Tourbillon, White Gold Case with Pink Gold Dial

Leave a comment

At SIHH 2019 in Geneva, A. Lange & Söhne unveiled a new Datograph Perpetual Tourbillon model (reference 740.056) featuring a white gold case with pink gold dial.

This watch incorporates a unique combination of a flyback chronograph, a perpetual calendar with moonphases, a tourbillon with stop seconds, and a power-reserve indicator.

The DATOGRAPH PERPETUAL TOURBILLON was launched in 2016. The term DATOGRAPH refers to a flyback chronograph with a precisely jumping minute counter and the typical Lange outsize date. PERPETUAL stands for its perpetual calendar with precisely jumping displays combined with a moon-phase indication calculated to remain accurate for 122.6 years.

Finally, the TOURBILLON part alludes to the one-minute tourbillon with patented stop seconds that is visible on the caseback side; it eliminates the influence of gravity on the escapement inside its cage. The well organised arrangement of the time, calendar and chronograph displays is rounded off with a power-reserve indicator at the end of the tachymeter scale.

A first 100-watch edition in platinum with a black dial is now followed by a second edition of 100 watches in white gold with a pink-gold dial. The new hue enriches the deliberately reduced spectrum of A. Lange & Söhne with a warmer nuance that creates a pleasant contrast to the cool charisma of the 41.5-millimetre white-gold case and the rhodiumed gold hands and appliques.

The development of the DATOGRAPH PERPETUAL TOURBILLON is powered by an impressive success story that began with the presentation of the first DATOGRAPH in 1999. Its rare combination of a classic column-wheel design, a precisely jumping minute counter and the flyback function attracted considerable attention. The clearly structured dial layout, in which the Lange outsize date and the two subsidiary dials form an equilateral triangle, gave it the status of a timeless icon.

The DATOGRAPH PERPETUAL TOURBILLON’s larger diameter made it possible to enlarge the subsidiary dials that accommodate the displays of the perpetual calendar. The subsidiary seconds, the day of the week and the day/night indicator are on the left side, while the precisely jumping minute counter, the months, and the leap-year indicator are on the right.

Three recessed correctors make it possible to adjust the moon phase, the day, and the month separately. A universal button at 10 o’clock advances all calendar displays collectively.

The sapphire-crystal caseback reveals the L952.2 manufacture calibre that consists of 729 parts. Finished manually down to the last detail, its complexity reflects the ambition of A. Lange & Söhne to continue to redefine the limits of mechanical watchmaking.

Chopard L.U.C All-in-One – Platinum and Rose Gold Limited Editions

Leave a comment

Chopard presents two versions – in platinum and rose gold – of the exclusive and ultra-complicated L.U.C 150 All-in-One watch that was originally introduced in 2010 in white gold edition to mark the company’s 150th anniversary.

The L.U.C All-in-One watch encompasses 14 indications on its two faces, including perpetual calendar and astronomical functions, as well as a tourbillon.

Entirely crafted in the Chopard Haute Horlogerie workshops, this tourbillon watch with perpetual calendar and astronomical indications comes in two 10-piece limited series: 10 in platinum and 10 in 18-carat rose gold.

Platinum version of the L.U.C All-in-One watch features an elegant hand-guilloché dial in a grey-blue colour and the rose gold model comes with an eye-catching hand-guilloché dial in a verdigris colour obtained by galvanic treatment.

Combining extreme complexity with the assured and distinctive elegance of the L.U.C collection, these timepieces bear the prestigious Poinçon de Genève stamp certifying Chopard’s exclusive craftsmanship and in-house manufacturing capabilities.

Designed for contemporary gentlemen, sure of their taste and fascinated by exceptional mechanisms, the L.U.C All-in-One is a symbol of Fine Watchmaking for the Maison Chopard. This grand complication watch subtly proclaims its horological sophistication on both sides and throughout the entire seven days of its exceptional power reserve.

The Chopard L.U.C All-in-One grand complication watch is equipped with L.U.C Calibre 05.01-L. With its 516 components, this movement comprises the largest number of complications ever offered within a single L.U.C watch. Its 14 indications spread between its twin faces sum up the broad range of skills mastered by Chopard Manufacture. Equipped with four barrels, this mechanical hand wound caliber can deliver seven days of exceptional power reserve.

The L.U.C All-in-One is graced with exceptional finishing throughout. The 46 mm case with its polished and satin-brushed surfaces is extremely ergonomic and thus makes a perfect fit on the wrist. All the case-back inscriptions are hand-engraved.

The dial is a solid gold plate with a guilloché motif radiating out from the large date at 12 o’clock. It is then coloured in grey blue to match platinum, and in verdigris for a bold combination with 18-carat rose gold. Even more meticulous concern for detail has been lavished on the 516 movement components, hand-crafted in accordance with the noblest traditional techniques.

The ergonomic and horological quality of the L.U.C All-in-One is also apparent in the legibility of its numerous complications. Each sector, indicator and gauge is perfectly sized. All clearly and generously display their respective information on exceptionally finely crafted dials.

On the front side, the perpetual calendar with large date display appears through large apertures and subdials, alongside a magnificently wrought tourbillon.

On the back, the equation of time, power reserve and sunrise and sunset times frame the orbital moon-phase indication.

Leave a comment

Celebrating its 150th anniversary in 2018, IWC Schaffhausen unveiled five limited-edition Portugieser wristwatches at the Salon International de la Haute Horlogerie (SIHH) in Geneva as part of the Jubilee collection.

The Portugieser Constant-Force Tourbillon Edition “150 Years” is one of the most technically sophisticated watches in the collection and combines a constant-force tourbillon with a simple moon phase display for the very first time.

The Portugieser Perpetual Calendar Tourbillon Edition “150 Years” brings a perpetual calendar together with a tourbillon on the dial for the first time ever. IWC is also launching a Portugieser with a perpetual calendar in the design of the Jubilee collection and fitting the Portugieser Chronograph with an IWC-manufactured calibre.

An anniversary edition of the Portugieser Hand-Wound is also being launched for fans of hand-wound watches.

All timepieces feature the design of the Jubilee collection. Their distinguishing features are the dials produced using a complex lacquering process in white or blue.

IWC Portugieser Constant-Force Tourbillon Edition “150 Years”

The Portugieser Constant-Force Tourbillon Edition “150 Years” (Ref. 5902) represents a technical highlight of the Jubilee collection.

A total of 15 watches will be made for each model:
– Platinum, white dial with lacquered finish, blued hands (Ref. IW590202)
– Platinum, blue dial with lacquered finish, rhodium-plated hands (Ref. IW590203)

IWC Portugieser Perpetual Calendar Tourbillon Edition “150 Years” (Ref. IW504501)

For the first time, the new IWC-manufactured hand-wound 94805 calibre with a power reserve of 96 hours combines a constant-force tourbillon with a simple Portugieser Perpetual Calendar moon phase display that only needs to be adjusted by 1 day after 577.5 years.

The patented constant-force mechanism transmits completely even impulses to the escape wheel. In conjunction with the tourbillon, which compensates for the negative influences of gravity on the watch’s oscillating system, this allows for an exceptionally high level of precision.

With the Portugieser Perpetual Calendar Tourbillon Edition “150 Years” (Ref. IW504501), IWC is combining a perpetual calendar with a tourbillon on the dial for the first time. The watch is available in a limited edition of 50: 18-carat red gold, white dial with lacquered finish, blued hands (Ref. IW504501).

This combination is possible thanks to the newly developed IWC- manufactured 51950 calibre. This is an extension of the 51900 calibre, with the addition of a perpetual calendar.

Made of 82 individual components and weighing just 0.635 grams, the tourbillon is visible at “12 o’clock” because the watch designers opened up the calendar advance ring and integrated the moon phase in the month display disc at “6 o’clock”.

With its solid gold rotor, the automatic winding system generates a power reserve of 7 days.

Breguet Marine Équation Marchante 5887 Platinum

With this new Grande Complication timepiece unveiled at Baselworld 2017, Swiss luxury watchmaker Breguet pays tribute to its rich tradition in the field of marine chronometers.

Throughout his career, A.-L. Breguet consistently demonstrated his exceptional mastery of time measurement. His strong involvement and his revolutionary developments earned him significant recognition and numerous honours.

In 1814, Louis XVIII, king of France appointed him a member of the Bureau des longitudes in Paris. This body created in 1795 by the National Convention was dedicated to the advancement of the various branches of astronomy and their applications to geography, navigation and geodesy (the measurement and understanding of Earth’s physical properties). Its tasks included the annual publication of reference documents such as astronomical ephemerides.

The Bureau des longitudes was a prestigious organisation whose 20 or so members included geometers, astronomers, seafarers and associate artists. The only representative of his profession that was eminently useful to physicists and navigators, Breguet became the horological authority, notably for the calculation of longitudes at sea. As an extension of this distinction, through an ordinance issued on October 27th 1815, Louis XVIII awarded A.-L. Breguet the official title of chronometer maker to the French Royal Navy.

This was the most prestigious title a horologist could hope to receive, given that the very concept of marine chronometry implied scientific knowledge. It also involved playing a crucial role for the country, as marine chronometers were of capital importance for fleets by making it possible to calculate ships’ positions at sea.

Following in the wake of this unique heritage, the House of Breguet now launches a worldwide exclusive model named the Marine Équation Marchante 5887. This “Grande Complication” marks the start of a new era for the contemporary Marine collection.

The equation of time is one of the rarest and most fascinating horological complications. It serves to display the difference between mean solar time, corresponding to civil or standard hours and minutes, and true solar time, meaning the actual solar hours and minutes.

Since Antiquity, the sun has been used as the basis of time. Nonetheless, the visible motion of the sun – the true solar time indicated on sundials – is irregular. With the improvement of timekeeping precision, watches and clocks became the basis of time and true solar time was replaced by mean solar time, within which each day has the same duration of exactly 24 hours. True solar time may show a discrepancy with mean solar time ranging from minus 14 minutes to plus 16 minutes.

On just four days a year, the two times are exactly the same. Given that the variations between true solar time and mean solar time are repeated in an identical manner on the same dates, watchmakers can reproduce them mechanically by means of a special cam. Shaped like a bean, the cam requires extremely accurate execution.

It is coupled with a feeler-spindle that drives an equation lever serving to indicate the difference between civil time and solar time. This read-off is generally provided on a sector or subdial. It is then up to the user to mentally add or subtract the difference displayed in relation to mean time in order to calculate true solar time. The new Marine Équation Marchante from Breguet supersedes this principle. It simultaneously indicates civil time and true time by means of two separate minutes hands.

The running solar hand, adorned with a facetted golden sun, provides a direct reading of solar time minutes that is both quicker and more user-friendly. This apparently simplicity conceals an arduous construction process that few watchmakers are capable of achieving. The solar minutes hand has to meet two imperative demands: it must sweep in a conventional way around the dial, like the civil minutes hand, while also daily moving away from the latter, in order to display true solar time taking into account the equation of time.

Breguet was able to accomplish this by equipping its running solar hand with a differential gear powered by two rotation sources operating entirely independently: the rotation of civil minutes, and that controlled by the lever in contact with the equation of time cam, which makes one full turn per year. Breguet has developed an extremely slim equation cam borne by using a transparent sapphire disc.

The complexity that the running equation of time brings to this model is naturally complemented on this “Grande Complication” by a perpetual calendar. Two apertures – one between 10 and 11 o’clock and the other between 1 and 2 o’clock – respectively display the days of the week as well as the months and the leap-year cycle.

The date appears inside the chapter ring by means of a retrograde hand tipped with an anchor motif and sweeping across an arc running from 9 to 3 o’clock. The dial layout of the information has been carefully designed to ensure simple and intuitive linear reading, along with impeccable visual appeal.

Based on the self-winding 581DR calibre, the new Marine Équation Marchante by Breguet also flaunts a third complication that is noteworthy in its own right: a 60-second tourbillon with a titanium carriage housing a Breguet balance with a silicon balance spring.

This innovative characteristic notably enables the balance wheel to achieve a 4Hz frequency, while maintaining a particularly comfortable power reserve for a self-winding model. This 80-hour autonomy is displayed through an aperture between 7 and 9 o’clock. The tourbillon appears through the sapphire disc bearing the equation of time cam, to which it is coaxial.

The ingenuity of this spectacular model is accentuated by the precious expertise of the artisans exercising their skills within the House of Breguet. The front dial features two types of engine-turning, including a “wave” pattern specifically developed for this new creation. The inscription “Marine royale” is engraved on the tourbillon bar, whose execution naturally draws the gaze.

Visible through a sapphire caseback, the bridges have been delicately chased to depict in meticulous detail the Royal Louis, a first rank vessel in the French Royal Navy. The barrel is adorned with a windrose motif, in reference to astronomical navigation. Thanks to the carefully chosen positioning of the oscillating weight on the rim of the calibre, the self-winding movement deploys the full splendour of its decoration.

The new Marine Équation Marchante by Breguet features new aesthetic signature codes giving it a modern and dynamic appearance: central lugs combining polished and satin-brushed surfaces; more open fluting, with visible flanks; a crown topped with a polished “B” against a sandblasted background; as well as a crown adorned with a chamfered and satin-brushed wave motif.

This Breguet Marine Équation Marchante 5887 watch comes with a 43.9mm-diameter case in rose gold or platinum. The rose gold version frames a silvered dial and an anthracite movement, while the platinum interpretation has a blue dial and a rhodium-plated movement.
