Audemars Piguet Frosted Gold Perpetual Calendar

Audemars Piguet's Royal Oak Frosted Gold Perpetual Calendar, reference 26574BC.GG.1224BC.01, has a 41 mm case in white gold with a frosted finish. The case measures 9.5 mm thick and carries a sapphire crystal over a black dial. Inside is the self-winding calibre 5134, a perpetual calendar movement tracking date, weekday and month alongside a moon phase display. This is a limited edition, and the calendar mechanism accounts for leap years without adjustment. The dial's counters pick out the calendar functions in blue and white against the "Grande Tapisserie" pattern. A hammered white gold bracelet with an AP folding clasp completes the piece. The case holds a water resistance rating of 50 metres.
