$ 377,000.00
Audemars Piguet Royal Oak Perpetual Calendar Openworked 25636PT is a rare and radiant expression of haute horlogerie, marrying technical complexity with sculptural beauty. Housed in a 39mm platinum case with the iconic octagonal bezel and exposed screws, the watch features a fully skeletonized dial that reveals the intricate workings of the Calibre 2120/2800SQ—at the time, the thinnest selfwinding perpetual calendar movement ever made, measuring just 3.95mm thick. The dial showcases blue chapter rings for the perpetual calendar functions: day, date, month, and moon phase, all arranged in a harmonious layout that balances legibility with visual drama.
