Vacheron Constantin Traditionnelle Twin Beat Perpetual Calendar

Vacheron Constantin's Traditionnelle Twin Beat Perpetual Calendar, reference 3200T/000P-H167, has a platinum case measuring 42 mm across and 12.32 mm thick. The grey dial is hand-guilloché and sits under a sapphire crystal, with a transparent section revealing the perpetual calendar mechanics beneath. Manual-winding calibre 3610 QP drives the watch, bearing the Geneva Hallmark, and delivers a power reserve of 1680 hours thanks to its dual-frequency Twin Beat system. The perpetual calendar shows date and month alongside a power reserve display and central seconds. A sapphire caseback exposes the movement's finishing. The case is fitted to a calf leather strap secured by a platinum pin buckle. Water resistance is rated to 30 metres.
