Audemars Piguet Selfwinding

Audemars Piguet's Royal Oak Selfwinding 15510ST.OO.1320ST.10 is a steel watch with a 41 mm case. The grey dial sits under a sapphire crystal and shows central seconds and a date. Inside is the self-winding calibre 4302, Audemars Piguet's in-house movement for this reference. The steel bracelet closes with an AP folding clasp. This is a straightforward three-hand watch built around the collection's established case architecture, without additional complications beyond the date. The movement winds automatically rather than by hand. The folding clasp secures a case that Audemars Piguet rates to 50 metres of water resistance.
