Audemars Piguet Royal Oak 26240ST, Stainless Steel, Black Index Dial, 41 mm

The Audemars Piguet Royal Oak Chronograph 26240ST is a masterful evolution of one of the most iconic luxury sports watches ever created, combining contemporary performance with the unmistakable design language introduced by Gérald Genta in 1972. Crafted entirely from stainless steel and measuring 41 mm, this exceptional timepiece showcases a striking black Grande Tapisserie dial with the collection’s signature tri-compax chronograph layout, accented by applied white gold index hour markers and luminous hands for outstanding legibility. The iconic octagonal bezel, secured by its exposed white gold screws, pairs seamlessly with the integrated stainless steel bracelet, whose meticulously hand-finished satin-brushed and polished surfaces demonstrate Audemars Piguet’s renowned craftsmanship. Powering the watch is the in-house selfwinding Caliber 4401, an integrated flyback chronograph movement visible through the sapphire crystal caseback. Offering approximately 70 hours of power reserve, the Caliber 4401 features a column wheel and vertical clutch architecture for precise, smooth chronograph operation, while the flyback function allows the chronograph to be reset and restarted instantly with a single push. The combination of the bold black dial, exceptional movement architecture, and impeccable finishing makes the Royal Oak Chronograph 26240ST one of the most sought-after modern references in the collection. With its timeless proportions, technical innovation, and enduring collector appeal, this Royal Oak represents the pinnacle of contemporary Swiss haute horlogerie.
