Audemars Piguet Royal Oak Perpetual Calendar 25829PT.OO.0944PT.01 – With Archive Papers

Audemars Piguet Royal Oak Perpetual Calendar Openworked 25829PT is a platinum-clad marvel that fuses avant-garde design with horological mastery, embodying the pinnacle of skeletonized complication within the Royal Oak lineage. Crafted from 950 platinum, the 39mm case and integrated bracelet deliver a commanding wrist presence, amplified by the iconic octagonal bezel with exposed screws. The skeletonized dial reveals the intricate architecture of the Caliber 2120/2802SQ, a self-winding movement that powers the full perpetual calendar suite: day, date, month, leap year, and moon phase. Each sub-dial is framed by delicate silvered rings and accented with blue details, offering both legibility and visual depth. The leap year indicator, subtly integrated into the month register at 12 o’clock, marks a technical evolution from earlier Royal Oak perpetual calendars.
