Vacheron Constantin Overseas self-winding

Vacheron Constantin's Overseas self-winding, reference 4520V/210R-B705, measures 41 mm across in rose gold. The case stands 10.69 mm thick and pairs with a sapphire crystal over a sunburst blue dial. Inside is the self-winding calibre 5100, certified with the Geneva Hallmark and good for 60 hours of power reserve. The dial shows a central seconds hand and a date aperture at 3 o'clock, with luminous hands and indices for low-light legibility. A screw-down crown protects the movement, and the sapphire caseback lets the finishing show through. The rose gold bracelet closes with a folding clasp in the same metal, and Vacheron Constantin rates the case to 150 metres.
