This Audemars Piguet Perpetual Calendar showcases the brand’s mastery of classic complications. Crafted in 18k yellow gold, the 36mm case houses a clean white dial with refined symmetry. Three subdials display day, date, and month, while a moonphase and leap year indicator sit at 6 o’clock, completing the perpetual calendar complication.
The thin baton hands and applied hour markers enhance legibility while keeping the dial elegant and understated. Powered by a self-winding movement, this reference blends technical complexity with timeless proportions, making it a versatile piece suited for both daily wear and formal occasions.
Produced during the late 1980s and early 1990s, the 25657BA represents a significant chapter in Audemars Piguet’s history, when perpetual calendars were engineered in remarkably slim profiles. Collectors prize this reference not only for its complication and gold construction, but also for its enduring design language that reflects AP’s haute horology tradition.
