AUDEMARS PIGUET. A COVETED AND ATTRACTIVE STAINLESS STEEL AUTOMATIC PERPETUAL CALENDAR WRISTWATCH WITH MOON PHASES, 'SAPPHIRE BLUE' DIAL AND BRACELET

Offered in very good overall condition, the present watch is one of only a handful of the extremely rare and hard to find stainless steel Royal Oak perpetual calendar reference 256545ST. Of high appeal, the present timepiece exemplifies itself through its excellent overall condition and highly unusual dial colour, providing it with a unique characteristic and personality. The present radiant blue version however is an exceedingly rare variant, nicknamed the 'Klein' Dial.

The Royal Oak Perpetual Calendar combines two of the great icons of Audemars Piguet’s heritage, the Royal Oak model and the perpetual calendar complication. Produced in very small numbers in stainless steel (approx. 315 pieces), the present reference 25654ST features a 'Sapphire Blue' dial with ‘Petite Tapisserie’ pattern. Audemars Piguet has always been associated with the making of complicated watches of the highest possible grade. At the same time the company has historically striven to be the leader in the production of the world’s thinnest watches with some notable milestones along the way - the movement is the exceptional caliber 2120 which has the distinction of being the thinnest automatic movement in the world with a full rotor. The rotor itself is decorated with hand-engraved detailing.
