Audemars Piguet 25661OR Quantieme Perpetuel Ultra-Thin 18K Rose Gold White Dial

The Audemars Piguet 25661OR.OO.A002XX.01 Quantieme Perpetuel Ultra-Thin in 18K rose gold stands as one of the most elegant perpetual calendars from the maison’s storied history. Fitted with a classic 36mm case, this reference exemplifies the refined proportions and ultra-thin construction that characterized AP’s perpetual calendars throughout the late 20th century—a period marked by the pursuit of technical mastery and understated luxury. The automatic Caliber 2120/2800, derived from the legendary Jaeger LeCoultre ebauche, is a true horological feat: celebrated for its featherweight rotor and remarkable thinness, it allowed Audemars Piguet to produce perpetual calendars of exceptional slenderness. The white dial, accented with applied 18K rose gold indices and slim matching hands, is a study in purity and sophistication. The 25661OR is distinguished by its beautiful stepped bezel and gracefully downturned lugs. Revered among collectors for its timeless elegance, mechanical pedigree, and role in cementing the perpetual calendar as an Audemars Piguet signature, the reference 25661 remains a benchmark of post-quartz-era haute horlogerie. In this white dial execution, its discrete aesthetic enhances the rarity and appeal for discerning enthusiasts. The watch is paired here with a luxurious burgundy alligator strap, elevating its presence further. Limited production numbers only add to its desirability among vintage and modern collectors alike.
