Audemars Piguet Royal Oak Selfwinding Chronograph 26240ST.OO.1320ST.01 – A Steel Legend Reborn

The Audemars Piguet Royal Oak Selfwinding Chronograph 26240ST.OO.1320ST.01 celebrates the legacy of the Royal Oak, blending its original design DNA with modern craftsmanship and cutting-edge mechanics. This 41mm stainless steel chronograph offers an ideal balance of sporty sophistication and timeless elegance.

The watch features a 41mm case crafted from stainless steel with brushed and polished surfaces, giving it a refined and dynamic appearance. At 12.4mm thick, the case maintains a slim profile while providing a robust presence on the wrist. The glare-proof sapphire crystal on the front and exhibition case back offer clear views of both the iconic dial and the finely decorated movement. Water resistance up to 50 meters ensures daily durability.

The dial is presented in the signature “Bleu Nuit, Nuage 50” shade, enhanced by Audemars Piguet’s renowned Grande Tapisserie pattern. The blue tone is rich and vibrant, providing a stunning backdrop for the matching chronograph counters. Applied white gold hour markers and Royal Oak hands with luminescent coating ensure excellent legibility while complementing the luxurious dial finish.

Powering the watch is Audemars Piguet’s in-house Caliber 4401. This integrated self-winding flyback chronograph movement includes a column-wheel mechanism, vertical clutch, and instantaneous jumping date. It operates at 4 Hz and offers a generous 70-hour power reserve. The movement is beautifully finished and can be admired through the transparent case back, which also features a 22k gold anniversary rotor.

The integrated stainless steel bracelet continues the Royal Oak tradition with a mix of brushed and polished links, ensuring a secure yet comfortable fit. The AP folding clasp provides both safety and ease of use while maintaining the watch’s streamlined aesthetic.
