Perpetual Calendar!
An exquisite masterpiece of haute horlogerie – the Audemars Piguet Perpetual Calendar Ref. 25661BA in the finest 18K yellow gold. This model is one of the most coveted and rarest perpetual calendars from the Le Brassus-based manufacture – a timepiece that perfectly combines technical brilliance, classic elegance, and exceptional exclusivity.
Reference 25661BA was produced between 1985 and 1994 – an era in which Audemars Piguet perfected the art of the ultra-thin perpetual calendar. Only 342 pieces were produced in total, of which just 244 were crafted in yellow gold. This rarity makes the watch a true collector's item and one of the most significant perpetual calendars of its time.
Measuring 36 mm in diameter, the watch presents classically balanced proportions and exudes timeless elegance. The case is in very good condition, with only light, age-appropriate signs of wear. The sapphire crystal caseback reveals the beautifully finished automatic calibre – finely decorated bridges with Geneva stripes, chamfered edges, and an elaborately engraved rotor that impressively reflects Audemars Piguet's craftsmanship.
The dial features the harmonious layout of the perpetual calendar, with displays for the date, day of the week, month, and moon phase – an aesthetically perfect balance that embodies the spirit of classic haute horlogerie.
The delivery includes an extract from the Audemars Piguet archives (2021), the original instruction manual, the watch booklet, and the original Audemars Piguet gold clasp.
Ref. 25661BA represents the quintessence of Audemars Piguet's watchmaking – technically sophisticated, harmoniously designed, and produced in strictly limited quantities.
An exceptional classic for connoisseurs and lovers of fine watchmaking – elegant, rare, and of lasting value.
