The Audemars Piguet Royal Oak Quantieme Perpetuel Ref. 25554BA represents the perfect fusion of Gerald Gentas iconic Royal Oak design and Audemars Piguets mastery of high complication watchmaking. Introduced in the 1980s, the reference marked the brands first integration of a perpetual calendar into the Royal Oak line an audacious move that transformed the sports-luxury watch into a stage for traditional horological artistry. Crafted entirely in 18k yellow gold, the 25554BA exudes warmth and depth, while its slim 39mm case and integrated bracelet maintain the unmistakable balance and proportion that define the early Royal Oaks.
This example stands out for its rich, tone-on-tone champagne dial, where the perpetual calendar indications are laid out in perfect symmetry day, date, month, and moon phase all framed by the unmistakable octagonal bezel and white gold screws. Its powered by the ultra-thin automatic Caliber 2120/2800, a movement that remains one of the finest expressions of mechanical finesse in Swiss watchmaking.
The watch is in outstanding original condition. The yellow gold case and bracelet retain their original geometry and factory brushing, with only minor wear consistent with use and a beautiful, even patina across the gold surfaces. The champagne dial is clean and free of flaws, its applied hour markers and blued hands showing exceptional preservation. The bracelet remains tight and well-articulated, maintaining the watchs original wrist presence.
A remarkable example of early Royal Oak sophistication, this Ref. 25554BA captures the essence of what makes the line so enduring: bold design, mechanical depth, and quiet, confident luxury a true icon of both its era and the Audemars Piguet legacy.
