Audemars Piguet Royal Oak Perpetual Calendar Yves Klein Enamel Dial

Audemars Piguet Royal Oak Perpetual Calendar Ref. 25820ST.OO.0944ST.02 is a highly coveted neo-vintage masterpiece renowned for its striking, electric "Yves Klein" blue lacquer dial. Housed in a slim, hand-finished 39mm stainless steel case with an ultra-thin profile of just 9.3mm, it perfectly retains the iconic "Jumbo" proportions originally conceptualized by legendary designer Gérald Genta. The mesmerizing dial features a traditional "Petite Tapisserie" geometric pattern and displays a full suite of perpetual complications, including the day, date, month, and a photorealistic moon phase indicator. Driven by the legendary, ultra-thin automatic Calibre 2120/2802, this rare execution is highly prized by elite collectors today for its mechanical pedigree, exceptional wearability, and the mesmerizing depth of its saturated cobalt-blue aesthetic.
