Audemars Piguet Perpetual Calendar

Audemars Piguet's Royal Oak Perpetual Calendar 26597PT.OO.1220PT.01 is a platinum limited edition with a 41 mm case. The black dial carries a perpetual calendar with date and central seconds, all set behind a sapphire crystal. This complication tracks leap years and month lengths without manual correction. As a limited edition, production of this reference is capped, adding a further layer of rarity to the platinum execution. The watch is fitted to a 950 platinum bracelet secured by an AP folding clasp. Weight and cool tone are the immediate impressions the metal gives on the wrist. Water resistance reaches 50 metres, respectable for a dress watch built around a perpetual calendar.
