The Audemars Piguet Royal Oak Selfwinding Chronograph Ref. 26240ST features a striking 41 mm stainless steel case paired with the iconic octagonal bezel and integrated bracelet. Its “Bleu Nuit, Nuage 50” blue dial showcases the signature Grande Tapisserie pattern, complemented by silver-toned chronograph counters, applied white gold hour markers, and luminescent hands. The combination of satin-brushed surfaces and polished bevels creates a refined yet sporty aesthetic that pays tribute to the Royal Oak’s 50-year legacy.

Inside, the watch is powered by Audemars Piguet’s in-house Caliber 4401 movement, offering flyback chronograph functionality, a column wheel, vertical clutch, and an impressive 70-hour power reserve. Visible through the sapphire crystal caseback is a commemorative 22-carat gold rotor engraved with “50 Years,” exclusive to the 2022 anniversary models. This reference seamlessly blends mechanical innovation with timeless design, making it a standout addition to any serious collection.
