Vacheron Constantin Overseas self-winding

Vacheron Constantin's Overseas self-winding, reference 4600V/200A-B980, measures 34.5 mm in steel. The case stands 9.33 mm thick. Sapphire crystal covers the sunburst blue dial, where gold hour and minute hands and hour-markers are highlighted with luminous treatment. The self-winding calibre 1088/1 drives central seconds and a date at 3 o'clock, and it stores 40 hours of power reserve. Through the sapphire caseback the oscillating weight in gold shows a wind rose motif. A steel bracelet closes on a folding clasp, with leather and rubber straps available thanks to an interchangeable system. Vacheron Constantin rates the case to 150 metres.
