Vacheron Constantin Overseas self-winding

Vacheron Constantin's Overseas self-winding, reference 4520V/210R-B967, is a 41 mm rose gold watch. The case measures 10.69 mm thick and holds a green sunburst dial with a date aperture at 3 o'clock. A sapphire crystal covers the dial, and the hands and indices carry luminous treatment for visibility. Inside is the self-winding calibre 5100, bearing the Hallmark of Geneva and offering 60 hours of power reserve. Central seconds run alongside the date function, and a sapphire caseback lets the movement show through. The rose gold bracelet closes with a rose gold folding clasp, and thanks to an interchangeable system it can also be fitted with leather or rubber straps. Rated to 150 metres, the case relies on a screw-down crown to keep water out.
