Audemars Piguet Selfwinding "50th Anniversary"

Audemars Piguet's Royal Oak Selfwinding "50th Anniversary" ref. 15510ST.OO.1320ST.01 measures 41 mm in steel. The blue dial has the Grande Tapisserie pattern and sits under a sapphire crystal. Inside is the self-winding calibre 4302, which drives the hours, minutes, centre seconds and date functions. Central seconds keeps the display clean and legible without extra dial clutter. The date sits alongside as the watch's other useful complication. A steel bracelet with an AP folding clasp completes the piece, matching the case in finish. The clasp secures a case that holds up to 50 metres of water resistance.
