Vacheron Constantin Saint-Gervais Grande Complication Watch

A tribute to the Cabinotiers established in the historical Saint-Gervais district, the cradle of grand traditional Geneva watchmaking, this creation perpetuates the enlightened and innovative approach adopted by the pioneers of which Vacheron Constantin is a direct descendant. Close to the brand’s historical headquarters located “En l’Ile” on the banks of the Rhône river, from the mid-18th onwards the Saint-Gervais district was home to the watchmakers and craftsmen working under the rooftops in order to find the silence they required and to enjoy the best possible light.
Vacheron Constantin Saint-Gervais Grande Complication WatchTogether, they constituted the prestigious Geneva “fabrique”. The Saint-Gervais commemorative series is a sparkling homage, 250 years later, to this fertile breeding ground and to the skilled craftsmen mastering the subtle gear-trains and the complicated mechanisms on which Vacheron Constantin has built its reputation. This exceptional creation serves to prove that their descendants are still worthy of their legacy and would not disappoint them in any way.
Vacheron Constantin Saint-Gervais Grande Complication WatchThe various functions clothed in the 44 mm case in 950 platinum call for 410 parts driving the hour and minute displays, small seconds at 6 o’clock, along with a tourbillon device. Calibre 2250 also incorporates a perpetual calendar indicating the day, the date, the month and the leap year. The movement is powered by four barrels, stacked in pairs and providing a total power reserve of 250 hours: the reserve is visible on the dial by double 125-hour segment indications, each winding down in turn. The power-reserve mechanism driven by the four barrels is patented.
Vacheron Constantin Saint-Gervais Grande Complication WatchThe ethereal, finely worked and extremely precise tourbillon is a classic, revolving once a minute. It is positioned at 6 o’clock in the traditional small seconds position. Optimised by the design-engineers of the brand’s Research / Development department based in Le Sentier (Vallée de Joux), the perpetual calendar displays its indications using the blued hands of the three day, month and date subdials respectively placed at 10, 12 and 2 o’clock. The discreet leap-year display appears through an aperture at 1 o’clock.
Vacheron Constantin Saint-Gervais Grande Complication WatchIn addition to the gold hour and minute hands, two additional blued steel hands can be seen running over the silvered dial in engine-turned gold, each sweeping across a segment at 3 o’clock and 9 o’clock. Their function is completely original, since they each indicate the power-reserve of barrels, which successively wind down one after the other.

Its four barrels provide a real and guaranteed power reserve of 250 hours, guaranteeing the smooth and undiminished operation of the movement and the functions. The development department has thus pushed existing limits and set the standard higher than ever before, especially in light of the fact that a comfortable additional margin guarantees that optimal efficiency has been duly verified. Nonetheless, for symbolic reasons, the brand has preferred to officially keep to 250 hours, the natural choice for this anniversary year.

As in all Vacheron Constantin watches, the high level of technical sophistication detracts nothing from the most accomplished forms of aesthetic expression. All the movement parts have thus been treated and decorated with meticulous care and in accordance with the uncompromising criteria of the Poinçon de Genève quality hallmark. The Saint-Gervais model is made in a limited series of 55.
