Catalogue Essay

-Launched in 1996 and in production until 2013, reference 25820 was made in a total of 1235 pieces including 378 pieces in stainless steel and platinum like the present example. It marked the introduction of the leap year indication on Royal Oak perpetual calendar models.

-The aesthetic impact of this breathtaking perpetual calendar Royal Oak is entrusted to the combination of its black dial and mirror-polished platinum bezel and platinum bracelet center links. While normally the Royal Oak bezel is satin-finished like most of the rest of the case, some rare examples - usually, but not exclusively, featuring platinum bezels such as in this instance - present this unusual mirror polishing. While it might sound as a simple detail, in fact this tweak changes dramatically the look of the piece. In this instance, the glimmer of the polished bezel is mirrored by the silvered chapter rings of the subsidiary counters. The final result is an ode to sporty elegance.

-The present watch is preserved in excellent condition with only very light signs of wear, it was serviced by Audemars Piguet in 2023.

Audemars Piguet

Swiss | 1881

A specialist in the manufacture of complications since it was established in 1881, Audemars Piguet never ceases to impress with a rich history of creating bold, even audacious, timepieces underpinned by traditional watchmaking at its finest. This Le Brassus-based Swiss manufacturer is one of only two major manufacturers still owned by the founding family. Since its earliest days, AP is considered a leader in the field of minute repeaters and grande complication pocket and wristwatches. The brand is devoted to preserving the history of watchmaking in the Vallée de Joux, showcased at their superb museum in Le Brassus.


Today, the brand is best known for its Royal Oak models, a revolutionary luxury sports watch launched in 1972. Other key models include early minute repeating wristwatches, vintage chronograph wristwatches, such as the oversized reference 5020, perpetual calendar watches and the Royal Oak Offshore, first introduced in 1993.
