Vacheron Constantin Patrimony self-winding jewellery

Vacheron Constantin's Patrimony self-winding jewellery, reference 4116U/000G-B909, measures 37 mm in white gold. The case stands 9.25 mm thick and holds a self-winding calibre 2460 SC/3, carrying the Hallmark of Geneva and a 40-hour power reserve. A sapphire crystal sits over the gold dial, and a matching sapphire caseback lets the movement show through. The watch is set with diamonds throughout. Central seconds is the only display function beyond the hours and minutes. The dark blue alligator leather strap closes with a white gold pin buckle and can be swapped without tools. Water resistance is rated to 30 metres, modest for a watch built around jewellery rather than sport.
