Vacheron Constantin Traditionnelle complete calendar

Vacheron Constantin's Traditionnelle complete calendar, reference 4010T/000G-B740, comes in a 41 mm white gold case measuring 10.72 mm thick. A sapphire crystal covers the dial, and the case carries the Hallmark of Geneva, a mark of quality reserved for watches finished to that seal's standards. Inside is the self-winding calibre 2460 QCL/1, with 40 hours of power reserve. The grey dial shows a complete calendar, with day and month in apertures at the rim and the date on a central pointer hand, alongside a moon phase and central seconds. A sapphire caseback reveals the movement. The watch is fitted to an alligator leather strap with a white gold pin buckle. Water resistance is rated to 30 metres.
