  • Catalogue Essay

    A new Royal Oak perpetual calendar model featuring this time a leap year indicator, reference 25820 was launched in 1996 and in production until 2013, 628 pieces in steel, 107 pieces in yellow gold, 74 pieces in platinum, 11 in pink gold, 378 in steel and platinum, 15 in tantalum and yellow gold, 9 in tantalum and platinum, and 13 in tantalum and pink gold for a total of 1235 examples.

    The aesthetic impact of this breathtaking perpetual calendar Royal Oak is entrusted to the combination of its black dial and mirror-finished platinum bezel. 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 bezel such as in this instance - present this unusual mirror finishing. While it might sound as a simple detail, in fact this different finish 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.

  • Artist Biography

    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.
