Audemars Piguet Royal Oak Perpetual Calendar Rose Gold — Silver Index Dial | Ref. 26574OR.OO.1220OR.01

Among the most intellectually ambitious expressions of Gerald Genta's 1972 masterpiece, the Royal Oak Perpetual Calendar in 18-carat rose gold stands as a testament to haute horlogerie within a sports-watch silhouette. The octagonal bezel, secured by its signature eight-hex screws and finished with an alternating polished-and-satin treatment, frames one of watchmaking's most coveted perpetual calendar displays — a complication that requires no manual correction until the year 2100.

Powering this piece is Calibre 2385, Audemars Piguet's in-house automatic perpetual calendar movement, beating at 19,800 vph and offering approximately 40 hours of power reserve. The movement orchestrates a continuous display of date, day, month, leap year, and moon phase with elegance and precision. Visible through the solid case back, its architecture reflects decades of accumulated manufacture expertise, with finishing standards befitting a grand complication.

The 41 mm rose gold case pairs with a matching rose gold integrated bracelet, unified by the hallmark tapisserie dial that shifts tone beautifully across changing light. With luminous-treated hands, index hour markers, and a date indicator at 6 o'clock, this reference balances legibility against complexity. A rare collector proposition, the 26574OR represents the perpetual calendar at its most wearable — priced for the connoisseur who demands both mechanical substance and uncompromising luxury.
