Audemars Piguet Perpetual Calendar

Audemars Piguet's Code Perpetual Calendar, reference 26394OR.OO.D027KB.01, has a 41 mm case in rose gold. The self-winding calibre 5134 drives the movement, with its functions visible under the sapphire crystal. The blue dial carries a full perpetual calendar display, showing date, month, weekday and moon phase. Leap year is tracked too, so the calendar accounts for it automatically. The moon phase itself references a starlit sky, part of the dial's astronomical theme. A blue rubber strap closes with a pin buckle in rose gold. Water resistance is modest here: the case holds to a rating of 30 metres.
