Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet's Royal Oak Selfwinding "50th Anniversary" ref. 15510OR.OO.1320OR.01 comes in an 18-carat pink gold case measuring 41 mm across. The blue dial sits under a sapphire crystal and shows a central seconds display alongside a date window. Inside is the calibre 4302, a self-winding movement built by Audemars Piguet for this reference. The hours and minutes are joined by centre seconds, with the date set at the usual position on the dial. Pink gold continues through to the bracelet, which closes with an AP folding clasp rather than a simple buckle. The case holds a rating of 50 metres, modest for the collection but standard for a dress-leaning Royal Oak.
