- A one-of-a-kind model in the grand watchmaking tradition
- Two original complications inherited from the Reference 57260 watch
- Four patent registered for the armillary tourbillon and retrograde displays
- Contemporary design enhanced by a titanium case
In the wake of the Reference 57260 watch and its 57 complications presented in 2015, this one-of-a-kind timepiece highlights two of its emblematic functions: the bi-axial armillary tourbillon with spherical balance-spring and the instant retrograde display of the time indications. This exceptional horological structure is housed in a titanium case, an ultra-light material that reveals the full depth of this model in a resolutely contemporary style. Four patents have been registered for the high-precision manual-winding 1990 calibre powering this watch.

The Reference 57260 watch, the most complicated timepiece in the world with its 57 complications, presented for the 260th anniversary of Vacheron Constantin in 2015, served as an authentic laboratory for the watchmakers of the Les Cabinotiers department. The research conducted throughout the eight years required to create and fine-tune this unique timepiece has enabled the development of original watchmaking techniques and solutions applicable to subsequent timepieces from the Manufacture. The Les Cabinotiers Armillary Tourbillon watch is the first to have benefited from these findings. Exuding a perfectly contemporary spirit, it reinterprets two complications introduced with Reference 57260: the instant double retrograde time indication and the bi-axial armillary tourbillon with spherical balance-spring.
An exceptional in-house calibre
The 1990 calibre, a mechanical manual-winding movement, drives the instant double retrograde hours and minutes function. On the right side of the watch, the large and small hands sweep over the semi-circle of the dial, with a strikingly fast return to zero once the 60 minutes and 12 hours have been reached. Such a display requires particular attention to its accuracy as well as to the strength of the materials used for a mechanism that is subjected to considerable strain. To provide the best possible view of its subtle details, the slate opaline dial is limited to a single chapter ring punctuated by Arabic numerals for the minutes and Roman numerals for the hours. This particular configuration of the time indications gives full scope to the armillary tourbillon bearing the small seconds, majestically displayed on the left side of the watch.

Contemporary design
These references to the great master watchmakers of the past are nonetheless expressed through perfectly contemporary watchmaking architecture in this Les Cabinotiers Armillary Tourbillon featuring extremely meticulous finishes. The 1990 calibre draws the gaze with its deep anthracite colour obtained by NAC (N-acetylcysteine) treatment applied by electrolysis. On the dial side, the calibre features a bold construction with clean-edged bridges and a "Clous de Paris" hobnail finish that perfectly highlights the aerial ballet of the tourbillon.

Les Cabinotiers: one-of-a-kind creations
In the Vacheron Constantin universe, Les Cabinotiers represents a department in its own right dedicated to the personalisation of pieces and unique creations. This tradition dates back to the 18th century, a time when master watchmakers were called cabinotiers and worked in ateliers bathed in natural light, known as cabinets and located on the top floors of Geneva's buildings. In the hands of these learned artisans, open to the new ideas of the Enlightenment, exceptional timepieces were born, inspired by astronomy, mechanical engineering and the arts. This expertise, which constitutes the great Geneva watchmaking tradition, has been flowing through Vacheron Constantin’s veins since 1755.
Résumé
The Reference 57260 watch, the most complicated timepiece in the world with its 57 complications presented for the 260th anniversary of Vacheron Constantin in 2015, has served as an authentic laboratory for the watchmakers of the Cabinotiers workshop. The one-of-a-kind Les Cabinotiers Armillary Tourbillon model benefits from these developments. In a perfectly contemporary spirit, it reinterprets two complications presented with Reference 57260: namely an instant double retrograde display and a bi-axial armillary tourbillon. On the right side of the watch, the large and small hands move over the semi-circle of the dial, with a strikingly fast return to zero once the 60 minutes and 12 hours have been reached. This particular configuration of the time indications gives full scope to the bi-axial armillary tourbillon with its silicon escapement and cylindrical balance-spring, majestically displayed on the left of the watch. Positioned beneath a bubble formed by the sapphire crystal, this structure consists of two nested carriages moving on two different axes at a speed of 60 seconds per rotation. Four patents have been registered for the retrograde system, escapement and tourbillon of the manual-winding movement (calibre 1990) driving this one-of-a-kind timepiece. This exceptional watchmaking architecture is housed in a titanium case, an ultra-light material that reveals the full depth of this model in a daringly modern style.
