Vacheron Constantin Patrimony self-winding

The Vacheron Constantin Patrimony self-winding 85180/000R-9248 comes in an 18K rose gold case measuring 40 mm across and 8.55 mm thick. Inside is the self-winding calibre 2450 Q6/3, carrying the Hallmark of Geneva and driving a central seconds hand along with the date. A sapphire crystal covers the champagne dial, and a matching sapphire caseback lets the finishing of the movement show through. The watch holds a 40-hour power reserve once fully wound. Set with diamonds, the dial's minute track adds a touch of sparkle to the otherwise restrained design. Vacheron Constantin pairs the case with an alligator leather strap closed by a rose gold pin buckle. That buckle and case together are built to a modest 30 metre depth rating.
