Audemars Piguet Royal Oak Perpetual Calendar 25654BA

An iconic, elegant and tasteful, Royal Oak Quantieme Perpetuel, automatic wristwatch in yellow gold, with white dial and Certificate of Origin, reference 25654BA.

Audemars Piguet’s Royal Oak needs little introduction. Conceived by Gérald Genta and launched in 1972, it redefined modern watchmaking by elevating the stainless-steel sports watch to the level of haute horlogerie. A decade later, Audemars Piguet achieved what few would have imagined: integrating a perpetual calendar into the bold, architectural case of the Royal Oak, an audacious blend of sport and high complication. The present Royal Oak Quantième Perpétuel, reference 25654BA, represents one of the most elegant expressions of that vision. Produced between 1982 and 1998, this yellow gold example bears individual number 967 and is preserved in outstanding overall condition. Its sharp case proportions, crisp edges and beautifully defined octagonal bezel with eight white gold screws testify to careful wear and excellent preservation. Crafted entirely in yellow gold, the watch combines visual warmth with technical sophistication. The clean white dial offers refined contrast against the gold case. Applied baton indexes and slender hands frame the classical perpetual calendar layout: day, date and month are displayed in three subsidiary counters, while a moon phase indication completes the ensemble. Despite its complexity, the dial remains remarkably legible and balanced, a testament to Audemars Piguet’s design mastery. Offered with its original accessories, this example embodies the unique duality of the Royal Oak: unmistakably sporty in design, yet deeply rooted in the highest traditions of Swiss complication watchmaking.
