The perpetual calendar has long occupied a special place in Audemars Piguet's history. During the late 1970s and early 1980s, the manufacture played a pivotal role in reviving complicated mechanical watchmaking, introducing some of the world's thinnest perpetual calendar wristwatches at a time when the Swiss watch industry was emerging from the Quartz Crisis. These elegant calendar models demonstrated that traditional haute horlogerie remained both technically relevant and aesthetically timeless, cementing Audemars Piguet's reputation as one of the foremost makers of complicated timepieces.

Produced around 1982, this reference belongs to the earliest generation of Audemars Piguet's landmark ultra-thin perpetual calendars. Reference 25548BA.OO.0002XX.01 exemplifies this important era of fine watchmaking. Crafted in 18K yellow gold, it showcases the understated elegance for which Audemars Piguet is renowned. The beautifully balanced white dial displays the perpetual calendar indications with remarkable clarity, including the day, date, month, moon phase, and leap-year cycle, all arranged in a harmonious layout that has become a hallmark of the manufacture's classic complicated watches.

At its heart is the ultra-thin Audemars Piguet Calibre 2120/2800, a self-winding perpetual calendar movement derived from the legendary Calibre 2120, one of the finest automatic movements ever produced. Celebrated for its slim construction, sophisticated engineering, and exceptional hand-finishing, the movement remains an icon of traditional Swiss haute horlogerie.

Fresh from its factory service, the watch has been inspected and serviced to Audemars Piguet's exacting standards and is accompanied by the official Audemars Piguet service report, further enhancing its desirability and collectability.

- Official Audemars Piguet service report 12/2025
