Audemars Piguet Selfwinding Perpetual Calendar

Audemars Piguet's Royal Oak Selfwinding Perpetual Calendar, reference 26684OR.OO.1356OR.01, has a 38 mm case in rose gold. The case measures 9.4 mm thick, and the champagne dial sits under a sapphire crystal. Inside is the self-winding calibre 7136, a perpetual calendar movement whose functions are set solely through the crown. The complication tracks date, weekday and month with a moon phase display, all adjusted without additional tools. This is a perpetual calendar built into a compact women's case, pairing technical depth with a smaller diameter. The rose gold integrated bracelet closes with an AP folding clasp. Water resistance reaches 50 metres.
