Vacheron Constantin Patrimony self-winding

Vacheron Constantin's Patrimony self-winding 4115U/000R-B907 has a 36.5 mm rose gold case. It measures 8.45 mm thick. The pink dial sits under a sapphire crystal and pairs with a display back, showing the finishing on the movement inside. That movement is the self-winding calibre 2450 Q6/3, carrying the Hallmark of Geneva and running with 40 hours of power reserve. Central seconds and a date function round out the display. The watch is set with diamonds, giving it a bit of sparkle against the plain gold. An alligator leather strap closes with a rose gold pin buckle. Water resistance stays modest at 30 metres, in keeping with a dress watch of this kind.
