This Audemars Piguet Perpetual Calendar Ref. 25682BA from the 1990s ranks among the rare and highly sought-after complications of classical watchmaking. Perpetual calendars from this era were produced in extremely small numbers and sold to a very discerning clientele. Combined with its rectangular yellow gold case, this timepiece embodies a restrained form of luxury that is rarely found today — elegant, and far from the mainstream. A truly impressive watch from one of the world’s most prestigious watch manufactures.
Equally exceptional is the silver dial, which follows the classic perpetual calendar layout and gains an additional level of exclusivity through its rare and finely executed Breguet numerals. Especially on rectangular Audemars Piguet perpetual calendars, Breguet numbers are exceedingly uncommon and lend the dial remarkable elegance and depth. The English calendar display is harmoniously integrated, while the recessed sub-dials ensure a balanced and calm overall appearance. The moonphase display at 6 o’clock completes the dial in a refined and tasteful manner.
At the heart of the watch beats a true masterpiece of horology: the legendary ultra-thin hand-wound Caliber 2003, which has been highly regarded since its introduction in 1946 and was developed in collaboration with Jaeger-LeCoultre. Audemars Piguet enhanced this movement with its in-house perpetual calendar module 2805 — a technical achievement resulting in an astonishing total thickness of just 3.19 mm. A compelling testament to the manufacture’s uncompromising engineering excellence.
This perpetual calendar is far more than a complicated wristwatch. It is a highly rare, aesthetically restrained classic with significant collector potential — created for connoisseurs who appreciate quiet excellence and historical significance.
