Audemars Piguet Royal Oak 15500

The Audemars Piguet Royal Oak reference 15500ST represents a significant evolution within the Royal Oak collection, succeeding the 15400ST. This reference introduced a redesigned dial layout and an updated in-house movement, signaling a modernization of the core three-hand Royal Oak offering. It maintains the distinctive Gerald Genta-designed aesthetic, characterized by its octagonal bezel and integrated bracelet, while refining internal mechanics and visual balance. This model features a 41mm stainless steel case with a thickness of 10.4mm, ensuring a balanced presence on the wrist. It is powered by the Audemars Piguet Caliber 4302, an automatic movement operating at 28,800 vibrations per hour and offering a substantial power reserve of 70 hours. The watch is fitted with a sapphire crystal and is water-resistant to 50 meters, providing practical durability for daily wear. Collector interest in the 15500ST often centers on its improved movement and the subtle dial refinements, which include a repositioned date window and the removal of the "Automatic" designation. It appeals to collectors seeking a contemporary interpretation of the Royal Oak with enhanced technical specifications. The reference is available in various dial colors, including blue, grey, and black, offering options within its established design language.
