In this new Traditionnelle creation, Vacheron Constantin combines unites two sophisticated horological complications: a mono-pusher chronograph and a tourbillon.
Crafted from 18K 5N pink gold, the new Traditionnelle tourbillon chronograph sets the stage for a tourbillon placed at 12 o’clock and a monopusher chronograph, reflecting Vacheron Constantin’s technical mastery in the field of Grandes Complications. “Etagé” case and lugs, a fluted case-back, a railway-type minute track, dauphine-type hours and minutes hands: the aesthetic codes of the Traditionnelle collection are all clearly present and the model Traditionnelle tourbillon chronograph showcases technical refinement conveyed through eminently horological characteristics.
Designed to compensate for the effects of the Earth’s gravity on watch mechanisms, the tourbillon is considered an iconic chorological complication. Often appearing on the lower part of the dial, as if to underline its role in supporting the optimal functioning of the watch, the tourbillon of the new Traditionnelle Tourbillon chronograph takes pride of place at 12 o’clock, where it draws all eyes.
In order to offer a perfect view of its fascinating ballet, the Manufacture’s developers have devised a novel movement mode for its carriage. Instead of being driven by the pinion of the fourth wheel, the tourbillon carriage is set in motion by an intermediate wheel of the running seconds display. This configuration enables an extremely wide opening onto the upper plate, thereby offering an even more spectacular view of the tourbillon.
The model also features a power-reserve indication at 6 o’clock and a 45-minute chronograph counter at 3 o’clock. The chronograph function monopusher inserted into the winding crown accentuates the technical side of the watch. It features a dynamic activation system (known as “all-or-nothing”) which prevents the chronograph mechanism from engaging when insufficient pressure is exerted on the pusher. It also revives the spirit of the original pocket chronographs before the mechanism migrated to the wrist: these models had only one pusher, often housed in the crown, which successively handled the start, stop and reset functions.
While the chronograph thereby recalls its origins, it also flaunts its vanguard performance credentials through the use of the “friction” technique for the lateral clutch mechanism combined with a column wheel, thus ensuring smooth activation of the function and preserving it from excessive wear over the long term. This technique also reduces potential stuttering of the chronograph hand when it is activated. Finally, the 45-minute counter with dragging display serves to reduce the loss of amplitude generally noted when the chronograph function is activated. When the latter is stopped, this type of display also serves to provide a more accurate time indication.
To power this timepiece, Vacheron Constantin has chosen a mechanism that is an integral part of its history, the 3200 calibre presented on the occasion of the Manufacture’s 260th anniversary. A technical masterpiece combining 292 components assembled by the most expert hands, this manual-winding tourbillon chronograph movement is distinguished by its 2.5 Hz frequency, which makes its steady beating visually easy to follow.
The aesthetic of the tourbillon carriage is inspired by the Maltese cross, its bar is entirely hand-finished and the finishes of the movement itself call upon the noblest horological traditions (chamfering, circular-graining, Côtes de Genève).
