Audemars Piguet Royal Oak Perpetual Calendar

The Audemars Piguet Royal Oak Perpetual Calendar 26574ST.OO.1220ST.01 is more than a luxury timepiece, it’s a discontinued collector’s icon. No longer produced by Audemars Piguet, this coveted reference is available only on the secondary market, making every example increasingly desirable as supply continues to shrink. Powered by the ultra-thin Caliber 5134, it mechanically tracks the day, date, month, leap year, week of the year, and moonphase, remaining accurate until the year 2100 without manual date correction when kept running. Paired with Gérald Genta’s legendary Royal Oak design, the signature “Grande Tapisserie” dial, and exceptional hand-finishing, this watch represents the perfect blend of technical mastery, exclusivity, and investment-worthy collectability. Owning one isn’t simply owning a watch, it’s securing a piece of Audemars Piguet history.
