Audemars Piguet Selfwinding

Audemars Piguet's Royal Oak Selfwinding 15510BC.OO.1320BC.01 is a limited edition case in 18-carat white gold measuring 41 mm across. The blue dial sits under a sapphire crystal and pairs with a white gold bracelet closed by an AP folding clasp. Inside is the self-winding calibre 4302, which drives hours, minutes, centre seconds and date. Audemars Piguet produced this reference as a run of 100 pieces. Central seconds and the date window are the only complications on the dial, keeping the layout clean. The case and bracelet share the same white gold, giving the whole watch a uniform tone. Water resistance reaches 50 metres, a figure the folding clasp and solid case construction help maintain.
