Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet Royal Oak Selfwinding "50th Anniversary" 15510OR.OO.1320OR.02 measures 41 mm across in 18-carat pink gold. The case follows the Royal Oak's revised ergonomic design and pairs with a black Grande Tapisserie dial under a sapphire crystal. Inside is the calibre 4302, a self-winding movement with hours, minutes, centre seconds and date. The date sits discreetly within the dial layout rather than as a separate window feature. A pink gold bracelet closes with an AP folding clasp, matching the case in tone and finish. This anniversary reference marks fifty years of the Royal Oak line while keeping its dimensions close to the original design. Water resistance reaches 50 metres, modest but standard for the collection.
