QUANTIEME PERPETUEL MODEL, REF. 25661PT, CASE NO. D 55739, NO. 45, CIRCA 1990

Introduced in 1985 and produced until 1994, the Quantieme Perpetuel reference 25661 represents one of the most refined perpetual calendar wristwatches created by Audemars Piguet during the revival of mechanical complications in the late 20th century. As mentioned on the certificate, it was released in a limited edition of 100 pieces. With the addition of a sapphire crystal caseback, the 25661 marked a significant evolution over the closely related reference 25657, enabling collectors to appreciate the exquisitely engraved automatic movement. This innovation improved the watch's technical and aesthetic appreciation.

Through tastefully sunken sub-dials for the day, date, month, and moon phase, the dial displays the perpetual calendar indications in a layout that is both harmonious and incredibly readable. Breguet numerals, whose delicate curvature gives the watch a distinctly classical character that accentuates its subtle elegance, further elevate the design.

The present reference 25661 in platinum with Breguet numerals stands as an exceptionally desirable configuration. Combining rarity, refined craftsmanship, and historical significance, it perfectly illustrates the manufacture’s mastery of complicated watchmaking and represents a remarkable opportunity for discerning collectors seeking an outstanding example of late 20th-century high watchmaking.
