Audemars Piguet Selfwinding

Audemars Piguet's Royal Oak Selfwinding, reference 77450ST.OO.1361ST.02, measures 34 mm across in stainless steel and stands 8.8 mm thick. A self-winding calibre 5800 drives the watch, shown through a sapphire crystal. The silver dial carries central seconds and a date display, with hours and minutes read off the same layout. Steel construction runs through to the bracelet, which closes with an AP folding clasp. This is a women's model, sized for a smaller wrist than the standard Royal Oak line. The case is rated to 50 metres of water resistance.
