  • 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 core concept of the Royal Oak, at its inception, was as simple as it was groundbreaking: a luxury steel watch. That is the cornerstone idea of the entire collection, and this example of reference 25820 is the modern complicated interpretation of such an idea. Incredibly light and absolutely sporty in feel and vibe, it features the iconic Royal Oak “tapisserie” dial but in a less common and extremely attractive silver color. Obviously, the fact that it is a perpetual calendar wristwatch elevates its complexity, rarity and collectability. It is remarkable how the brand managed to render such a complicated piece with such an eminently wearable and sporty feel, and it is because of this that it can be said this watch truly encapsulates the “spiritual values” of the Royal Oak collection.

  • 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.
