The Royal Oak 26240ST modernizes the Royal Oak chronograph platform through refined case ergonomics, revised dial symmetry, and the integration of Audemars Piguet’s latest generation chronograph movement. Its 41mm stainless steel architecture preserves the instantly recognizable Royal Oak silhouette while subtle updates to the pushers, bracelet transitions, and dial spacing create a cleaner and more technically balanced visual composition.

At the center of the reference is the integrated Calibre 4401 flyback chronograph movement, developed entirely in house by Audemars Piguet. Visible through the sapphire caseback, the movement reveals a column wheel chronograph mechanism, vertical clutch system, and refined decorative finishing throughout the bridges and rotor. The 26240ST stands as one of the most mechanically advanced modern Royal Oak chronographs currently produced.
