Vacheron Constantin Patrimony self-winding

Vacheron Constantin's Patrimony self-winding, reference 4110U/000G-B906, measures 36.5 mm across in white gold. The case stands 8.45 mm thick and carries the Hallmark of Geneva, the movement's certification of finish. Inside is the self-winding calibre 2450 Q6/3, giving 40 hours of power reserve and visible through a sapphire caseback. A sapphire crystal also covers the blue dial, which is set with diamonds around its minute track. Central seconds and a date aperture round out the display. The watch is fitted on a dark blue alligator leather strap with a white gold pin buckle. Water resistance is modest here: the case holds to 30 metres.
