A modern expression of Geneva’s grand watchmaking tradition, the new Traditionnelle tourbillon chronograph combines the precision of a monopusher chronograph with the sophistication of the tourbillon, a complication single-handedly symbolising the nobility of Haute Horlogerie. “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.
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.
Manufacture Calibre 3200
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.
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.
