The mechanical self-winding Calibre 2460 SCC has been entirely designed, developed and manufactured by the Manufacture Vacheron Constantin. This state-of-the-art movement is equipped – just like the most prestigious models in the century-old history of the Chronomètre Royal – with a stop seconds device enabling the wearer to stop the watch completely and thus achieve adjustment to the nearest second. Beating to the cadence of 28,800 vibrations per hour and endowed with a power reserve of approximately 43 hours, Calibre 2460 SCC drives central hour, minute and seconds hands. Its construction incorporated ceramic ball-bearings used in the rotation of the oscillating weight, thereby avoiding any need to lubricate the bearings and guaranteeing its durability.
In keeping with its noble rank, Calibre 2460 SCC is also distinguished by the careful bevelling work on the bridges decorated with the Côtes de Genève motif, and by the circular graining on the mainplate: this meticulous finishing, worthy of the finest Haute Horlogerie models, can be duly admired through the sapphire crystal case-back.
