AUDEMARS PIGUET Classique Ref. 25641BA DayDate Moonphase – 1986

The reference 25614BA occupies an interesting transitional position within Audemars Piguet’s calendar watchmaking of the 1980s. Crafted entirely from 18k yellow gold and fitted with its original solid gold bracelet, the watch combines traditional dress-watch proportions with the technical sophistication of AP’s emerging neo-vintage era. At its heart is the ultra-thin automatic Calibre 2124/2825, displaying the day, pointer date and moon phase. While the reference 25614BA is not a perpetual calendar, it belongs to the same important period of Audemars Piguet calendar watchmaking and shares its movement with the celebrated Royal Oak Day-Date Moonphase Ref. 25594. With its elegant 33 mm case, balanced calendar display and integrated gold bracelet, this 1988 example is a rare and impressive neo-vintage Audemars Piguet. An increasingly difficult-to-find transitional reference and an appealing alternative to the better-known perpetual calendars of the period.
