Audemars Piguet Royal Oak Chronograph 26240ST.OO.1320ST.01 '50th Anniversary' Stainless Steel Blue Dial (2022)

The Audemars Piguet Royal Oak Chronograph Ref. 26240ST.OO.1320ST.01 “50th Anniversary” marks a milestone moment for one of the most important designs in modern watchmaking. Crafted in stainless steel and sized at 41mm, this reference represents the updated Royal Oak Chronograph introduced to celebrate 50 years of Gérald Genta’s original 1972 creation. The case features refined proportions compared to previous generations, with slightly reworked pushers, a slimmer profile, and enhanced ergonomics, all while preserving the Royal Oak’s unmistakable architecture—octagonal bezel, exposed screws, and sharp brushed and polished surfaces.

The blue “Grande Tapisserie” dial is instantly recognizable and deeply tied to the Royal Oak’s identity. Its rich tone adds depth and contrast against the stainless-steel case, while applied hour markers and hands ensure crisp legibility. The tri-compax chronograph layout remains balanced and purposeful, with subdials for running seconds and elapsed time arranged cleanly across the dial. A discreet date window at 4:30 integrates naturally, maintaining visual harmony without interrupting the dial’s symmetry. As a 50th Anniversary piece, this reference carries subtle commemorative details that underscore its place in Royal Oak history.

Finished with the integrated stainless-steel bracelet, the 26240ST offers exceptional comfort and a seamless flow from case to wrist. Powered by a modern automatic chronograph movement designed for everyday reliability, this reference represents the definitive contemporary steel Royal Oak Chronograph.
