Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet's Royal Oak Selfwinding "50th Anniversary", reference 15510OR.OO.D315CR.01, measures 41 mm in rose gold. The case pairs with a blue dial and sits under a sapphire crystal. Inside is the calibre 4302, a self-winding movement with hours, minutes, centre seconds and date. Central seconds gives the dial a clean sweep, and the date sits in its own window without disrupting the layout. The watch is fitted to a blue alligator leather strap, closed by a folding clasp in rose gold to match the case. It is a solid, dressier take on the Royal Oak line rather than a sports-focused version. The case carries a water resistance rating of 50 metres, modest for daily wear but standard for this reference.
