Shanghai, September 6th, 2021 – Since its founding in 1755, Vacheron Constantin has perpetuated watchmaking expertise drawing upon the mastery of the most advanced knowledge and technology. This demanding know-how, which the Manufacture has continually enriched throughout its history and continues to explore, is illustrated through a wide range of horological complications. From the split-seconds chronograph to the perpetual calendar, from the minute repeater to Grand Complication combinations, the “Technical Achievements” exhibition brings together a selection of eight 20th century masterpieces.

“To do better if possible, and that is always possible”: these words written by François Constantin in 1819 sum up the visionary spirit and quest for excellence of the Vacheron Constantin artisans. From the first watches made in 1755 to the present day, the Manufacture’s heritage is replete with creations testifying to consistent daring and a taste for innovation. A journey through the archives of the Maison demonstrates the true scope of the skills passed down through several generations of passionate and curious master-watchmakers, as well as the progress of science and watchmaking genius. 

Through a selection of eight historical models, “Technical Achievements” pays tribute to the mechanical feats achieved in Vacheron Constantin’s workshops during the 20th century. Retrograde displays, split-second chronographs, perpetual calendars, minute repeater, Grande Sonnerie models and watches with multiple complications are brought together in this exhibition. From pocket watches to the art of wearing time on the wrist, they reflect the wealth of Vacheron Constantin’s technical repertoire and the desire to continually nurture the expertise accumulated over the centuries. The exhibition is also a reminder of the extent to which the Manufacture has always endeavoured to place technique at the service of style. Thanks to the miniaturisation of calibres and their constant technical evolution, Vacheron Constantin has demonstrated tremendous artistic creativity. The result is a signature touch in which a taste for innovation meets a keen sense of elegance.

Retrograde displays
The design and adjustment of a movement with retrograde indications requires great technical virtuosity. First and foremost, the development of such a mechanism implies mastery of the considerable forces brought into play by the instantaneous return of the hands over an almost 180° arc in a mere fraction of a second. It also implies perfect energy management in order to enable the sudden movement of the hand. This technical tour de force enables time to be displayed in an original way while maintaining the inherent precision requirements of Haute Horlogerie timepieces. 

Watchmaking history reveals that retrograde displays already appeared in pocket watches during the late 17th century. These featured an hour hand that travelled across an arc for half the day before returning to its starting point to begin all over again. Vacheron Constantin has been incorporating retrograde displays into its creations since the end of the 18th century. The originality of this complication enabled it to give free rein to its technical creativity.

Among the most famous models is a ‘bras en l’air’ (‘arms in the air’) movement presented in 1930 in a pocket watch case bearing the signature of Verger Frères. Subsequently, Vacheron Constantin produced other original interpretations depicting a fakir or a Chinese magician whose arms replaced the retrograde hands to indicate the hours and minutes. Over the following decades, these ‘arms in the air’ models inspired multiple contemporary variations of the retrograde display, such as the Mercator and Saltarello wristwatches created in the 1990s. These are among the most striking examples of Vacheron Constantin’s technical and aesthetic daring – a heritage that the Manufacture continues to enrich through highly sophisticated models added to its current collections, such as the Patrimony moon phase retrograde date watch – Collection Excellence Platine unveiled in 2020. The one-of-a-kind Les Cabinotiers Armillary tourbillon perpetual calendar – Planeteria presented in 2021 also presents an innovative interpretation of this complication by integrating a triple retrograde indication for the date, months and days.

Chronographs and split-seconds chronographs
The chronograph is one of the most recent horological complications: it was not until the early 19th century that watchmakers achieved a sufficient level of precision to develop a system for measuring short times by means of a mechanism enabling a hand to be stopped and restarted without hindering the movement. This invention was quickly followed by another equally brilliant one designed to measure several events simultaneously by means of a double hand system. Invented in 1838, the split-seconds chronograph remains one of the most sophisticated mechanical developments and is greatly appreciated by watch enthusiasts.

As functional as it is technically ingenious, this mechanism serves to time actions starting at the same time but of different durations. When the watch is activated, the chronograph hand and the split-second hand are superimposed. When the pusher is pressed, the split-second hand stops while the chronograph hand continues its progression. After memorising an initial time, a further press releases the split-seconds hand, which then synchronises instantly with the chronograph seconds hand that is still running. This operation can be repeated as many times as necessary to carry out several successive timing operations.

Vacheron Constantin joined the fray at an early stage by incorporating the chronograph complication into elegant pocket watches that were particularly sought after at turn of the 20th century, in an era when the world was becoming fascinated by sports competitions and horse races. Thanks to the progress made in the miniaturisation of its movements, the Manufacture was also quick to adopt the complex column-wheel chronograph mechanism in elegant watches from 1917 onwards.

A number of historical models well-known to collectors for their bold design and unfailing reliability testify to this tendency. Among them is a 1942 chronograph, Reference 4083, which stands out both for its legibility and for the design of its double-cylinder lugs. Another example is the prestigious Reference 4072, a chronograph produced by Vacheron Constantin between the 1930s and the early 1970s, which owes its exceptional longevity to its timeless design and the exceptional quality of its movements.

Faithfully cultivated throughout the last century, the expertise of the Manufacture’s artisans in the field of chronographs is alive and well, as demonstrated by ingenious interpretations such as the Traditionnelle split-seconds chronograph ultra-thin – Collection Excellence Platine. Introduced in April 2021, this timepiece is powered by the prestigious self-winding Calibre 3500, one of the finest to date for this type of complication.

The perpetual calendar
The perpetual calendar is one of the trickiest horological complications to develop. Considered a masterpiece of horological genius, this mechanism takes into account the variations of the Gregorian calendar so as to automatically adjust to months of 30 and 31 days or 28 and 29 days in February, without requiring any correction until 2100. To do this, the movement must have a mechanical memory whose sequences are repeated every 48 months. The solution is a cam, a component consisting of notches of varying depths. The deeper the notch, the shorter the month. This information from the cam is transmitted via a feeler spindle to a large lever that operates the various displays. It represents a technical solution to an astronomical and mathematical problem that Vacheron Constantin addressed by presenting its first perpetual calendar watch in 1884.

For almost a century, the Manufacture used this technical prowess exclusively in pocket watches. Thanks to progress in movement miniaturisation and the trend towards increasingly large wristwatch diameters, the 1980s marked a turning point with the 1983 creation of the first perpetual calendar to be fitted in an ultra-thin wristwatch (Reference 43031). Its movement, the prestigious Calibre 1120 QP, constitutes a technical challenge and is still majestically enthroned in the most demanding creations of the Manufacture, such as the Overseas perpetual calendar ultra-thin. Its latest skeletonised variation, presented in 2021 in a white gold case, enables viewers to admire – both on the dial side and through the sapphire crystal caseback – the components of Calibre 1120 QPSQ/1, delicately hollowed out, finished and decorated in the finest traditions so as to enhance the functional beauty of the mechanism.

Engaged in a continuous quest for innovation, Vacheron Constantin also expanded its technical repertoire with the Traditionnelle Twin Beat perpetual calendar watch presented in 2019. The 3610 QP calibre powering this timepiece is endowed with a dual frequency, enabling its owner to reduce the watch’s energy consumption when it is not on the wrist. This action serves to extend the power reserve to at least 65 days – a technical advance that gives real meaning to the term “perpetual”and opens up new perspectives for traditional watchmaking.

Minute repeaters and Grande Sonnerie models
Born of the need to tell the time in the dark at a time when people were still reliant on candlelight, chiming watches have been one of Vacheron Constantin’s great specialities for more than two centuries and are available in various forms. The Manufacture’s watchmakers have repeatedly distinguished themselves through strike-on-demand, minute repeater (striking the hours, quarters and minutes on demand, Petite Sonnerie (striking the hours and quarters without repeating the hours at each quarter) and Grande Sonnerie (striking the hours and quarters with a repetition of the hours at each quarter) complications. Among these, the sophisticated Grande Sonnerie mechanism is considered by connoisseurs as the pinnacle of musical watches. Few watchmakers are capable of mastering the demands involved in its design and construction: the synchronisation of the components must not only be perfect in order to set the time to music, but also to ensure the reliable operation of the movement, as any interference between the different functions is likely to damage the mechanism. The issue of energy management is also crucial, given that the movement orchestrates 912 hammer strikes on the gongs every 24 hours. Not to mention the harmonic tone and acoustic power that make the creation of such a model an exercise reserved for the most experienced watchmakers.

The Manufacture’s archives attest to the first chiming timepiece created in 1806 by the founder’s grandson, Jacques Barthélemi Vacheron. The first watch with a Grande Sonnerie mechanism signed Vacheron Constantin dates back to 1827. Since then, the Manufacture has consistently cultivated and enriched this heritage, to the point of becoming a benchmark for the most illustrious collectors such as the Maharajah of Patiala, who commissioned a pocket watch with chronograph, alarm, date and moon phases in 1909; as well as American car manufacturer James Ward Packard, for whom Vacheron Constantin created a pocket watch equipped with a chronograph, a quarter and half-quarter repeater, and a Grande Sonnerie in 1918. Over the course of the century, orders poured in from all over the world for Vacheron Constantin’s repeater watches and Grande and Petite Sonnerie complications, combining virtuoso mechanics with impeccable acoustic resonance. The Manufacture continues to perpetuate this expertise today, notably through one-off models such as the Les Cabinotiers minute repeater tourbillon sky chart – Leo constellation Jewellery watch, whose Calibre 2755 TMRCC combines a minute repeater with a tourbillon and drives a rotating map of the celestial vault.

Grand Complication combinations
As early as 1900, Vacheron Constantin set up a workshop exclusively dedicated to watches with complications. It is here, where the most seasoned watchmakers rub shoulders, that high-flying watches are born.

Housed in elegantly sculpted gold cases, several extremely complex mechanisms are combined. Two examples reflect the technical mastery of Vacheron Constantin’s artisans in the creation of Grand Complications, whose golden age reached its peak between the 1920s and 1930s: a triple complication from 1901 combining a minute repeater, a chronograph with a tachymeter scale and an astronomical perpetual calendar; as well as a 1910 hunter-type watch featuring a perpetual calendar, a quarter repeater and a moon-phase indication. 

Nearly a century later, the Manufacture is continuing its epic technical saga by combining the traditional principles of watchmaking with the latest mechanical advances. In 2015, after eight years of research, Vacheron Constantin unveiled Reference 57260, the most complicated timepiece ever made. This double-dial pocket watch features 57 complications, including multiple calendars and a split-seconds chronograph with double retrograde display.

This unique expertise in the field of Grand Complications is also illustrated through wristwatches showcasing a resolutely 21st century style. Presented in 2020, the one-of-a-kind Les Cabinotiers split-seconds chronograph – Tempo is the most complicated wristwatch ever made by Vacheron Constantin. On its two sides, it displays a split-seconds chronograph, a perpetual calendar, several astronomical functions, a tourbillon and a minute repeater. This mechanical tour de force is orchestrated by an exceptional calibre featuring 24 complications and 1,163 components.

Watches exhibited
Round ‘arm in the air’ Chinese magician pocket watch, Ref. Inv. 11060 – 1930
Between the 1920s and the 1930s, Vacheron Constantin unabashedly displayed its creative daring on pocket watches with retrograde displays. This is particularly evident in this 1930 two-tone yellow and white gold watch: an engraved and enamelled gold Chinese magician on its satin-brushed silver-toned dial shows the hours with his right arm and points to the minutes with his left arm.

 “Mercator” wristwatch with map of Europe, Asia & Africa, Ref. Inv. 12130 – 1996
Created to mark the 400th anniversary of the death of the father of cartography, Gérard Mercator, this 18K yellow gold wristwatch is distinguished not only by the refinement of its hand-engraved dial representing Mercator’s map of Europe, Asia and Africa, but also by the originality of its retrograde display. The compass-shaped hands respectively indicate the retrograde hours and minutes on two sectors placed on the lower part of the dial.

Saltarello wristwatch, Ref. Inv. 11000 – 1998
Over the years, Vacheron Constantin has developed the retrograde display complication in numerous stylistic variations. At the heart of the cushion-shaped yellow gold case of the Saltarello model, Vacheron Constantin has opted for a refined design: the jumping hours are indicated through an aperture, while the retrograde minute hand sweeps majestically across the centre of the sunburst silver-toned dial.

Split-seconds pocket chronograph, Ref. Inv. 11288 – 1939
The split-seconds chronograph is undoubtedly one of the most sophisticated mechanical developments in terms of its design and the sophistication of its settings. In 1939, Vacheron Constantin combined it with a base 1000 tachymeter scale in this 18K yellow gold pocket watch. Alongside its technical performance, the watch’s legibility is also of the utmost importance: the 30-minute counters and the small seconds hand are harmoniously arranged on the silver-toned dial swept over by two split-seconds hands.

Wrist chronograph, Ref. Inv. 11017 – 1942
The particularly close ties woven in the late 19th century with the Parisian case manufacturer Verger Frères influenced the aesthetics of the timepieces produced by Vacheron Constantin. These were combined with various technical developments in the 1920s, highlighted by ever more audacious designs. This style signature can be seen on this famous 18K red gold chronograph produced in 1942, whose 33mm case features particularly original cylinder-type lugs.

Perpetual calendar wristwatch, Ref. Inv. 10736 – 1988
In 1984, Vacheron Constantin fitted a wristwatch with a perpetual calendar movement for the very first time. Hailed for its precision and reliability, this prestigious Calibre 1120 QP, which can still be found in the Manufacture’s contemporary collections, equipped this platinum watch from 1988 onwards. The understated and particularly legible dial displays the perpetual calendar and moon-phase indications.

Minute repeater pocket watch, Ref. Inv. 10607 – 1908
A true feat of miniaturisation and acoustic quality, this round pocket watch produced in 1908 houses minute repeater and Grande Sonnerie mechanisms within its 18K red gold case. Its enamelled dial is punctuated by a small seconds counter at 6 o’clock. On the back, the case is decorated with a polychrome enamel crest topped by a crown.

Perpetual calendar pocket watch, quarter repeater, moon phases, Ref. Inv. 10722 – 1910
As early as 1900, Vacheron Constantin set up a workshop specially dedicated to the assembly of watches with grand complications, such as this 18K yellow gold hunter-type pocket watch combining a quarter-repeater, a 48-month astronomical perpetual calendar, moon phases and a small seconds-hand. This prestigious model is distinguished by the perfect legibility of the indications harmoniously arranged on a white enamel dial.
