Audemars Piguet Selfwinding

Audemars Piguet's Royal Oak Selfwinding 15551BC.ZZ.D405CR.01 is a women's model in 18-carat white gold, measuring 37 mm across and 9.1 mm thick. The case is set with diamonds, and the grey dial sits under a sapphire crystal. Inside is the self-winding calibre 5900, which drives the hours, minutes, centre seconds and date. Central seconds and date are the only complications, kept simple against the diamond-set case. The alligator leather strap closes with a folding clasp in white gold, itself set with diamonds. Water resistance reaches 50 metres, a sensible figure for a dress watch of this type.
