Audemars Piguet Perpetual Calendar

Audemars Piguet's Code by Audemars Piguet Perpetual Calendar, reference 26394OR.OO.D321CR.01, has a 41 mm case in rose gold. The dial is blue, paired with a sapphire crystal, and set with subdials that display the watch's calendar functions. Inside is the self-winding calibre 5134, which drives a perpetual calendar with date, weekday, month and moon phase indications. The perpetual calendar mechanism accounts for leap years without adjustment, so the date carries forward correctly across the full four-year cycle. A hand-stitched blue alligator strap closes with a folding clasp in rose gold. Water resistance sits at a modest 30 metres, in keeping with the watch's dress orientation.
