Audemars Piguet Perpetual Calendar

Audemars Piguet's Royal Oak Perpetual Calendar 26615TI.OO.1220TI.01 comes in a 41 mm titanium case, part of a limited edition of 300 pieces. The salmon "Grande Tapisserie" dial sits with matching subdials under a sapphire crystal. Inside is the self-winding calibre 5134, an in-house perpetual calendar movement tracking the day, date, week, month and leap year. A moon phase display rounds out the astronomical functions on the dial. The perpetual calendar is the standout complication, coordinating the calendar indications without manual correction. A titanium bracelet with an AP folding clasp completes the piece, matching the case in weight and tone. Water resistance is rated to 50 metres.
