The Audemars Piguet Royal Oak Perpetual Calendar 25654ST.OO.0944ST.01 is a landmark reference in modern watchmaking, representing one of the earliest integrations of a perpetual calendar within a luxury sports watch. Introduced during a period when such complications were rare, it established the Royal Oak as both a design icon and a platform for high horology.
Housed in a 39mm stainless steel case faithful to the original “Jumbo” proportions, the watch maintains an exceptionally slim profile while accommodating a full perpetual calendar display. The silver dial, characteristic of early production, features a clean layout with subdials for day, date, month, and moonphase, offering both clarity and balance.
Powered by the ultra-thin selfwinding Caliber 2120/2800, derived from one of the most respected automatic movements ever produced, this timepiece combines technical sophistication with refined execution. A rare and historically significant piece, it remains highly sought after by collectors of early Royal Oak complications.
