2460 R31R7

This automatic mechanical movement, engineered and manufactured by Vacheron Constantin, features hours, minutes, and retrograde day and date displays. Introduced in 2005 for the brand's 250th anniversary, this 11½-ligne (25.6 mm) double-complication calibre beats at 28,800 vibrations per hour with over 40 hours of power reserve. The 2460R31R7 showcases refined finishing, including Côtes de Genève bridges, circular-grained plates, a 22K gold guilloché rotor on ceramic bearings, and bears the Poinçon de Genève hallmark as a testament to its durability and horological excellence.
