The Royal Oak Selfwinding Chronograph 26240ST.OO.1320ST.05 combines sportiness and refinement in a 41mm stainless steel case with integrated bracelet. Its striking “Bleu Nuit, Nuage 50” dial, decorated with the Grande Tapisserie pattern, is paired with white gold hour markers and luminescent Royal Oak hands for exceptional legibility. Featuring a flyback chronograph, small seconds, and a discreet date window, this model balances elegance with practicality. Powered by a selfwinding movement offering a power reserve, it is both reliable and versatile. A modern expression of Audemars Piguet’s watchmaking heritage.
