Presented in an elegant 39mm white gold case set with baguette-cut blue sapphires to complement the blue dials, the watches are powered by the ultra-thin self-winding manufacture movement with a tourbillon, Calibre 2160.

The quest for decorative beauty: hand-guillochage and gem-setting

The Métiers d'Art Tribute to The Celestial watches celebrate Vacheron Constantin's savoir-faire in the artistic crafts of hand-guillochage and gem-setting. Since the Maison was founded 270 years ago, the mastery of such métiers d'art has been transmitted from one generation to the next, nurturing the Maison's continuing quest for beauty and aesthetic refinement.

Each of the 12 dials depicts a hand-guilloché zodiac sign and its associated constellation, with the principal stars represented by brilliant-cut diamonds. In addition to the guilloché, the four signs representing human figures (Gemini, Virgo, Sagittarius and Aquarius) feature opaline details. The craft of guilloché figurative drawing was developed by Vacheron Constantin's own master guillocheur, going beyond the abstract patterns of classical guillochage to enable the creation of illustrations and thus transform the traditional craft into a figurative art form in its own right.

The innovative technique, which calls for great dexterity and precision, involves the creation of a multitude of hand-guilloché triangles formed of densely packed straight lines, with each triangle set at a different angle from its neighbours. To create just one zodiac sign requires approximately 16 hours of intense and conscientious work.

Enhancing the blue colour of the dial and highlighting the gem-setting expertise of Vacheron Constantin's in-house métiers d'art workshop, a total of 96 baguette-cut blue sapphires (~3.87  carats) are set into the bezel and onto the crown, lugs and buckle, requiring 27 hours of gem-setting work. On the bezel, the choice of channel-setting, in which the stones are held between two parallel tracks with no metal separating them, gives the impression that the sapphires are floating, to create an uninterrupted circle of light around the dial. Echoing the linear geometry of the baguette sapphires and the fine lines that form the guilloché motifs, the applied white gold indexes are decorated with a ribbed surface pattern.

Construction of the dials is a complex and meticulously orchestrated process involving eight separate steps. For each artisan, the challenge of the craft itself is amplified by the need to ensure that the work of the preceding craftsman is not compromised in any way. To begin, the dial base, a thin disc of 18K 5N gold, is marked with the outlines of the constellations and zodiac signs. Then, a sunburst finish is applied to the entire dial and the opaline details added to the four 'human' signs. The next step is the hand-guillochage of the zodiac sign. Only when this is completed can the aperture for the tourbillon be cut out, after which the blue colour is applied. Then, to define the map of each constellation, the dial is machined to reveal the gold dial base in a tracery of fine lines. On completion of this step, a protective varnish is applied to the entire dial.

Then come the final details: the transfer-stamping of the minutes and seconds tracks and the Vacheron Constantin name; the application of the white gold indexes and the Maison's Maltese Cross emblem; and finally, setting of the diamonds that mark the principal stars in each constellation. Appropriately, the word constellation is derived from the Latin constellatio, which can be translated as “set with stars”.

Haute Horlogerie mechanism and finishes: a finely crafted ultra-thin tourbillon movement – Calibre 2160

For 270 years, Vacheron Constantin's quest for watchmaking excellence has been built on the marriage of technical expertise, fine craftsmanship and finishing. Uniting an Haute Horlogerie movement with intricate, hand-decorated dials, the Métiers d'Art Tribute to The Celestial series represents the highest expression of this philosophy.

Winding the mainspring to provide an 80-hour power reserve, the 22K gold peripheral oscillating weight also allows an unobstructed view of the meticulously finished movement. Perlage on the mainplate is complemented by hand-bevelled bridges decorated with Côtes de Genève, circular-grained wheels and chamfered and polished screws. On the dial side, a heat-blued fastening screw contrasts with a hand-polished tourbillon bar and Maltese Cross-shaped tourbillon cage.

Each Métiers d'Art Tribute to The Celestial watch bears the Poinçon de Genève, guaranteeing provenance, precision of timekeeping and the finest finishing of both functional and decorative movement components.

An ode to the constellations and zodiac signs

Since the dawn of time, mankind has been fascinated by the beauty and mystery of the night sky. Ancient observers attempted to decipher the rhythms of the cosmos and interpret celestial patterns in ways that reflected their worldviews and cultural beliefs.

In Bronze Age Mesopotamia, around 5,000 years ago, astronomers identified many of the distinctive groupings of stars that form constellations, naming them after the animals, mythological figures and objects that they imagined the patterns depicted. Greek and Roman civilisations later infused many of these constellations with their own mythology and adopted many of the names used today. Different cultures – including Chinese, Indian and Native American – also interpreted the night sky and created distinct constellation systems according to their own beliefs.

Blending these ancient traditions with more recent discoveries, 88 constellations are officially recognised today – 36 of which lie mainly in the northern sky and 52 in the southern celestial hemisphere. Although the former had been catalogued as early as the second century CE by the Greco-Roman astronomer Ptolemy, the latter were not identified until pioneering Dutch navigators began charting the southern skies in the late 16th century.

Among these 88 constellations, the 12 zodiac constellations recognised in Western astrology are those that lie along the plane of the ecliptic – the apparent path of the Sun across the sky as seen from Earth. Because the cycle of the Sun's passage through the zodiac is aligned with the seasons, ancient cultures used that cycle to determine what subsequently became defined as a year. To this day, astrology associates each zodiac sign with a specific point in the seasonal cycle. The word zodiac is derived from the ancient Greek zoidiakos, meaning 'circle of animals'.

In creating this ode to the constellations and the zodiac, Vacheron Constantin evokes the charm of the founding myths and acknowledges the ancient and intimate link between astronomy and astrology. In Babylon and ancient Egypt, the roles of astronomer (predictor of celestial phenomena) and astrologer (interpreter of those phenomena) were performed by the same person, and until the 17th and 18th centuries, both professions were practised side by side – including by the great astronomers Galileo Galilei and Johannes Kepler, who also practised astrology.

Comprising 12 references, each celebrating one of the zodiac constellations and its associated astrological sign, the Métiers d'Art Tribute to The Celestial series has taken inspiration from a single-piece edition created in 2021 by Vacheron Constantin's Les Cabinotiers workshop, the Minute Repeater Tourbillon Sky Chart Leo Constellation Jewellery.

The dial of that watch – portraying the Leo zodiac sign in figurative guilloché along with its corresponding, diamond-set constellation – a opened a new territory of artistic expression for Vacheron Constantin.

Celestial themes have been central to Vacheron Constantin since its earliest years. As well as developing a rare degree of expertise in watches dedicated to the influence of astronomical phenomena on timekeeping, the Maison has a considerable legacy of aesthetic and figurative pieces depicting the zodiac.

Notable examples include an Art Deco table clock in gold, onyx, rock crystal and lapis lazuli displaying the zodiac signs created in collaboration with Verger Frères in 1927. In 1996, as part of the Mercator collection, the Maison presented Ref. 43050, with a polychrome enamel dial depicting the Chinese zodiac signs. In 2012, it inaugurated 'Legend of the Chinese Zodiac', a series within the Métiers d'Art collection presented over a 12-yearly cycle, beginning with the snake and followed by each year by the associated sign. Zodiac signs also appeared on the 2017 Métiers d'Art series, Copernicus Celestial Spheres. Marking its 250th anniversary in 2005, Vacheron Constantin presented l'Esprit des Cabinotiers, a mystery clock on which the dial was encircled by the 12 zodiac signs, created in miniature-painted grand feu enamel. More recently, the zodiac calendar has featured on a series on single-piece editions: Les Cabinotiers Astronomica (2014), Reference 57260 (2015), and The Berkley Grand Complication (2024).

INTERVIEW WITH SANDRINE DONGUY, PRODUCT & INNOVATION DIRECTOR

In what ways does the Métiers d'Art Tribute to The Celestial series best illustrate Vacheron Constantin's values and expertise?

When he founded the Maison in 1755, Jean-Marc Vacheron took a particular approach to watchmaking, as he considered technical excellence to be intrinsically linked to aesthetics, in terms not only of the dial and case but also the form and finishing of the internal components. This approach still defines Vacheron Constantin today and, by giving equal value to Haute Horlogerie and the decorative crafts, these watches truly express the essence of the Maison. In addition to the artistic decoration of these watches, the slimness of Calibre 2160 exemplifies the way that our watchmakers synthesise technicality and beauty: the technical challenge lies in the need for smaller and finer components, while the aesthetics are honoured by the proportions of the slim case that a thin calibre makes possible.

Vacheron Constantin has a distinguished legacy in displaying both Western and Chinese zodiac signs. What was the reason for combining the zodiac signs with the constellations for these pieces?


Given the technical and mathematical nature of timekeeping, Vacheron Constantin is naturally aligned with astronomy, and yet we also appreciate the poetic nature of astrology, with its sense of mystery and romance. Until the time of Galileo, astrology and astronomy were regarded as a single science – that of observing and analysing celestial phenomena, which is the very foundation of time measurement. Métiers d'Art Tribute to The Celestial series has enabled us to bring these elements together in a different way of expressing the beauty of the night sky.

How do the métiers d'art chosen for these watches represent the Maison's commitment to preserving tradition while constantly innovating?

Vacheron Constantin created its in-house Métiers d'Art workshop not only to help preserve this savoir-faire but also to support the artisans in innovating, exploring and developing new techniques. The figurative guilloché technique used on these dials is an excellent illustration of how this approach encourages the continuing evolution of traditional crafts. It was developed by Vacheron Constantin's master guillocheur and goes beyond the abstract patterns of classical guillochage to become a decorative art form in its own right. For the gem-setting, our master gem-setter has employed different techniques for different elements, each chosen to enhance the brilliance of the stones according to their cut and their position on the piece: channel setting on the bezel creates the impression of an uninterrupted circle of sapphires, while the brilliant-cut diamonds that represent the stars on the dial were grain-set from the reverse side.

VACHERON CONSTANTIN – LES CABINOTIERS Temporis Duo Grand Complication Openface - Unique Piece


VACHERON CONSTANTIN LES CABINOTIERS Temporis Duo Grand Complication Openface – Minute Repeater Perpetual Calendar Chronograph - Unique Piece 2025

  • A single-piece edition timepiece combining mechanical excellence and aesthetics in the great tradition of the watchmaking complications that have marked the history of the Maison
  • A new open-faced sapphire dial reveals the beauty and complexity of the movement
  • A technical feat of rare complexity, Calibre 2757 S incorporates a single push-piece split-seconds chronograph, a minute repeater and a tourbillon regulator with a spherical hairspring
  • Aesthetically faithful to the Maison's exacting standards, with fine hand-finishing on all components of the calibre, which is visible beneath an open-faced sapphire dial

To bring together in a wristwatch a minute repeater, a split-seconds chronograph and a tourbillon regulator is a technical challenge that has rarely been met. In the Les Cabinotiers Temporis Duo Grand Complication Openface these complications benefit from Vacheron Constantin's latest technical developments and continuous research into materials.

Particular attention has also been paid to the decoration and hand-finishing of Calibre 2757 S, which comprises almost 700 components. This work is revealed through the complex sapphire dial as well as the sapphire back of the 45mm 5N pink gold (750/1000) case. This highly technical timepiece turns mechanical watchmaking into a kinetic art form that measures time.

The evolution of age-old know-how 

 The complications of this new Les Cabinotiers timepiece epitomise the transmission of watchmaking expertise through the generations – a core value of Vacheron Constantin. In 1819, the Maison produced a pocket watch with independent deadbeat seconds and a quarter repeater, one of the first of its kind. The watch incorporated a deadbeat seconds mechanism – a device that had been developed by various watchmakers in the late 18th century as a means of more accurately measuring very small units of time.

 Designed as an independent mechanism with its own gear train, it enabled the seconds hand to be stopped and restarted independently of the normal timekeeping function and is thus considered to be the forerunner of the chronograph.  

  Click, to see the large size. BIG FOTO 

The split-seconds chronograph mechanism has two coaxial hands, the second of which can be stopped to calculate an intermediate time before being restarted to catch up with the first. After the system was introduced – first with a single-hand system in 1831, then with the two-hand configuration in 1838 Vacheron Constantin quickly incorporated these developments into its pocket chronographs.

The Maison's chiming watches draw on an equally deep history. Minute repeaters – watches that strike the hours, quarters and minutes on demand – have been part of Vacheron Constantin's watchmaking vocabulary for more than two centuries. The first mention of a Vacheron Constantin striking timepiece in the production records is a gold quarter-repeating pocket watch recorded in 1806.

Since then, the Maison has continued to build its expertise in striking and repeating watches. Created in 1827, the first Vacheron Constantin watch with grande and petite sonneries, is an impressive example of this savoir-faire, as are Reference 4261 dating from the early 1940s, which incorporates a minute repeater in a calibre just 3.28 mm thick, and Reference 57260 which counts a grande et petite sonnerie (the former with Westminster chimes), a minute repeater, and an alarm among its 57 complications.

A similar historic evolution applies to the tourbillon. This mechanism, which significantly enhances isochronism by mitigating the effects of gravity, is first mentioned in the Maison's archives with an order placed in 1901 by a Parisian client for a highly complicated timepiece that was to incorporate such a regulator. Over the decades, Vacheron Constantin's watchmakers have continued to develop the tourbillon, notably by developing technical solutions with multiple axes. The Les Cabinotiers Tourbillon Armillaire bi-axial wristwatch with a spherical hairspring and the Les Cabinotiers – The Berkley Grand Complication, featuring a triple-axis tourbillon, are outstanding examples of this expertise. 

  Click, to see the large size. BIG FOTO 

While the combination of a chronograph and a minute repeater in a movement with a tourbillon regulator has been seen in some remarkable pocket watches, it has remained rare in wristwatches. Vacheron Constantin saw this as an opportunity to create such a piece, in the tradition of the grand complication watches that have made its reputation for 270 years.

Three of Haute Horlogerie's most emblematic complications, the chronograph, minute repeater and tourbillon are among the most difficult to create, let alone combine. Meeting the challenge, in 2022 the Maison unveiled Calibre 2757 in a single-piece edition Les Cabinotiers watch offering this rare and original combination in a single mechanism.  

  Click, to see the large size. BIG FOTO 

For the Les Cabinotiers Temporis Duo Grand Complication Openface, , the watchmakers of Les Cabinotiers developed a new version of the calibre, with a spherical hairspring to further improve isochronism, and set it in a one-of-a-kind watch that reveals the beauty and complexity of the movement through an open-worked dial. 

Horological mastery 

The highly technical Calibre 2757 S incorporates 696 components, with the design of the movement, particularly in terms of its chronograph functions, subject to the imperative of performance. Despite its complexity, the watchmakers at Vacheron Constantin have created a movement of great finesse, barely 10.4 mm high and 33.3 mm in diameter, remaining faithful to the principles of elegance that are a signature of the Maison. 

  Click, to see the large size. BIG FOTO 

When developing the original Calibre 2757, the additional split-seconds chronograph plate was specially designed with an in-depth arrangement of its components to enhance operating efficiency. This optimisation of volumes to ensure the calibre's thinness, was complemented by the use of new materials. Some of the wheels in the gear train have been made of titanium or electroformed in nickel-phosphorus, with a toothing profile particular to Vacheron Constantin that ensures improved penetration of the gears to prevent the second hands from shaking.

After much research, the chronograph seconds hands were made of aluminium, chosen for its rigid and ultra-light properties. Silicon, another ultra-light material that requires no lubrication, was used for one of the split-seconds levers and its insulator. These savings in component weight and friction reduce the loss of energy amplitude from the barrel. This contributes to a comfortable power reserve of 50 hours with the chronograph engaged, indicated by a display on the back of the watch.

With measurements accurate to 1/5th of a second thanks to the movement's frequency of 18,000 vibrations per hour, elapsed time is indicated on the peripheral minute track by the two central second hands, together with a 30-minute counter positioned at 2 o'clock. Because this function demands extremely high precision, Vacheron Constantin's watchmakers opted for a construction with two column-wheels, one devoted to the chronograph and the other to the split-seconds hand.  

  Click, to see the large size. BIG FOTO 

The chronograph is controlled by a single push-piece at 2 o'clock for the basic functions (start/stop/reset) and by a push-piece at 4 o'clock for the split-seconds (stop/reset). Pressing the latter stops the second hand at an intermediate time while the first hand continues its course. When pressed again, the split-seconds hand instantly joins the first hand in the time countdown. 

A centripetal regulator and spherical hairspring 

The minute repeater featured in Calibre 2757 S has also benefited from technical developments at Vacheron Constantin. These include an ingenious flying strike governor. This device has two weights shaped so as to act as a brake on the governor's rotating shaft, thus evening-out the energy released by the repeater's spring. To achieve this, it uses opposing centrifugal and centripetal forces. When the governor spins, the centrifugal force pivots one end of the weights outwards so that the other end acts as a brake on the central shaft to bring the rotation and the strike to a steady rate. 

  Click, to see the large size. BIG FOTO 

The governor mechanism, which operates in total silence, regulates both the cadence and  duration of the musical sequence so that the notes can be heard distinctly and clearly, with a complete absence of mechanical 'background noise'. The distinctive feature of this system is its two flyweights with a shape specially designed to generate a kind of 'motor brake' by a centripetal force acting on the governor's rotating shaft. This evens out the energy released by the minute repeater barrel.  

  Click, to see the large size. BIG FOTO 

Located at 6 o'clock, the tourbillon is fitted with a spherical hairspring, a shape that causes the spring to expand and contract concentrically, thus enhancing isochronism. The distinctive tourbillon cage is inspired by the Maltese cross, the Maison's emblem. Held in place by a hand-bevelled bridge. the tourbillon performs one complete rotation per minute and a hand mounted on its axis indicates the small seconds. 

Technical excellence enhanced by Haute Horlogerie finishes 

 A transparent sapphire dial is the aesthetic signature of the new Les Cabinotiers Temporis Duo Grand Complication Openface. Just 0.5 mm thick, it is distinguished by a highly complex mix of finishes:  polished and frosted surfaces alternate on the counters, which are encircled by rings in 5N gold, applied by metallisation on the underside of the sapphire discs; the hour markers are treated with grey NAC and the chronograph markers are engraved and inked. The 30-minute chronograph counter hand and the two chronograph seconds hands are made of PVD-coated aluminium – their olive green colour matched by the green alligator leather strap that attaches the 45mm pink gold case to the wrist.

 The sapphire dial and caseback reveal the quality of the hand-finishing on the movement components, highlighting the beauty of this kinetic artwork. Surfaces are, variously, bevelled, polished, satin-finished, grained, circular-grained, engraved and bead-blasted, creating a fascinating play of reflections and light.  

Visible through the dial, the sides of the skeletonised bridges are hand-drawn and hand-bevelled and the surfaces are circled. The wheels, with their bevelled spokes, are rolled and polished, a delicate operation that requires special tools when wheels are made of titanium. The metallic colours of the moving parts contrasts with the black NAC coating on the bridges and main plate. 

  Click, to see the large size. BIG FOTO 

On the reverse side of the movement, the watchmaker has created a distinctive decoration. The surface of the blackened bridges was hollowed out then sandblasted by hand to a very fine grain and edged with a mirror-polished sink. The hand-chamfered sinks for the jewels and screws have also been mirror-polished. The beauty of the movement architecture is amplified by the contrast between the black bridges, their polished borders and the golden tones of the moving parts. The striking governor is engraved with the initials JMV, in homage to Jean-Marc Vacheron, and held by a semi-circular bridge that has been round-polished by hand – the polishing alone requiring eight hours of meticulous work.

Thanks to the meticulous attention to detail dedicated to this calibre, it took twice as long for the finishing of its components as it did to assemble and fit it into the case. As was the case for the 18th-century cabinotiers, a single watchmaker was in charge of the watch, carrying out all of the component finishing, as well as every assembly operation, right down to the adjustment and casing of the calibre. This manner of working is an eloquent testimony to Vacheron Constantin's commitment to safeguarding the transmission of watchmaking expertise through the generations.
