The Audemars Piguet Royal Oak Tourbillon Extra-Thin 26510ST.OO.1220ST.01 is an exceptional expression of the brand’s pioneering approach to high-end watchmaking. Combining the unmistakable Royal Oak aesthetic with an impressive tourbillon complication, this timepiece is housed in a 41mm stainless steel case with an elegant yet distinctly sporty character. Its extra-thin profile further enhances its refined proportions.

The blue dial is finished with Audemars Piguet’s signature textured pattern, creating depth and visual interest while providing a sophisticated backdrop for the time display. White-gold applied hour markers and Royal Oak hands ensure excellent legibility, with luminescent coating providing visibility in low-light conditions. Surrounding the dial is the characteristic octagonal stainless steel bezel, secured by the collection’s signature exposed hexagonal screws. The combination of the deep blue dial, polished and brushed steel surfaces and distinctive bezel gives the watch its unmistakable Royal Oak presence.

Completing the design is an integrated stainless steel bracelet that flows naturally from the case, reinforcing the seamless architecture for which the Royal Oak is renowned. The bracelet combines comfort with a robust, luxurious appearance and is secured by an Audemars Piguet folding clasp. Its integrated construction ensures that the bracelet remains visually connected to the case, maintaining the watch’s balanced proportions and sporty-elegant character.

At the heart of the 26510ST.OO.1220ST.01 is the manually wound Audemars Piguet Calibre 2924, a sophisticated mechanical movement incorporating a tourbillon escapement. The tourbillon is visible through the open sapphire crystal caseback, allowing the intricate mechanism to be admired while it operates. The movement provides approximately 70 hours of power reserve and features hours, minutes, a power reserve indicator, and a tourbillon. The sapphire crystal protects the dial, while the case offers water resistance to approximately 50 metres. The movement’s fine finishing and complex construction demonstrate Audemars Piguet’s expertise in haute horlogerie and its long-standing commitment to technical innovation.

The Audemars Piguet Royal Oak Tourbillon Extra-Thin 26510ST.OO.1220ST.01 is a remarkable combination of iconic design and sophisticated mechanical engineering.
