Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet presents the Royal Oak Selfwinding "50th Anniversary", reference 15510ST.OO.1320ST.04, in a 41 mm steel case. The dial is green with the collection's Grande Tapisserie pattern, and it sits under a sapphire crystal. Inside is the self-winding calibre 4302, which drives central seconds and a date function. The case follows the Royal Oak's familiar ergonomic profile, updated for this steel reference. A steel bracelet closes with an AP folding clasp, giving the watch a consistent finish from case to strap. Water resistance is rated to 50 metres, enough for daily wear and the occasional splash, though not for diving.
