Vacheron Constantin Overseas self-winding

Vacheron Constantin's Overseas self-winding, reference 4520V/210A-B483, is a steel watch with a case measuring 41 mm across and 10.69 mm thick. The black dial carries a date aperture and central seconds, with luminous hands and indices for legibility. Sapphire crystal covers the dial, and a sapphire caseback shows off the movement inside. That movement is the self-winding calibre 5100, bearing the Genevian Seal and running with 60 hours of power reserve. A screw-down crown protects the case, a practical detail on a watch built for daily wear. The steel bracelet closes with a folding clasp, also in steel. Vacheron Constantin rates the case to 150 metres.
