Vacheron Constantin Les Cabinotiers Armillary Tourbillon
· 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.
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.
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.
