Audemars Piguet 25977ST Royal Oak Tourbillon Chronograph SS Blue Dial

The Audemars Piguet Royal Oak Tourbillon Chronograph reference 25977ST.OO.1205ST.01 is a rare and technically formidable expression of the Royal Oak lineage. Introduced in the 2000s and produced in very limited numbers, this 44 mm stainless steel model unites two of horology’s most revered complications—a tourbillon and chronograph—within the iconic octagonal Royal Oak case. Its deep blue "Grande Tapisserie" dial, punctuated by luminous white hands and indexes, offers exceptional legibility and visual depth, while the tourbillon aperture at 6 o’clock underscores the watch’s mechanical sophistication. Powering the piece is the in‑house Caliber 2889, an automatic movement delivering approximately 72 hours of power reserve, beautifully finished with Côtes de Genève and anglage visible through the exhibition caseback. The integrated stainless steel bracelet, with its interplay of satin-brushed and polished surfaces, reinforces the Royal Oak’s architectural elegance and sporty heritage. Collectors prize this reference not only for its technical merit but also for its rarity and the seamless fusion of haute horlogerie with the Royal Oak’s groundbreaking design ethos.
