Full-Cataloguing
Two iterations have been made for the model, a more sporty one with blue dial and red accents, perhaps inspired by “racing” dials, and the present monochrome black variation, for a more sleek livery. Powered by the manual wound caliber 2889 beating at 21,6000 vph, this highly accurate timepiece boasts a power reserve of up to 72 hours. Rarely seen on the market, the present lot is accompanied by an Audemars Piguet Certificate of Origin and Exclusivity, presentation box, and accessories.
Audemars Piguet
Swiss | 1881A 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.
