The Audemars Piguet Royal Oak Chronograph reference 26240ST.OO.1320ST.02 represents a pivotal evolution of one of the most iconic sports watches ever created. Released in 2022 to commemorate the 50th anniversary of the Royal Oak, this reference combines Gérald Genta’s original design language with Audemars Piguet’s most advanced in-house chronograph movement to date.
Executed in stainless steel with a black Grande Tapisserie dial, the 26240ST offers a more refined and balanced take on the Royal Oak chronograph. The 41mm case features updated proportions, slimmer pushers, and a redesigned integrated bracelet that enhances both comfort and presence on the wrist. The monochromatic dial layout reinforces the watch’s versatility, making it equally suited for daily wear or more formal settings.
Powering the watch is Audemars Piguet’s in-house Caliber 4401, a modern flyback chronograph movement with column wheel architecture and a 70-hour power reserve. Visible through the sapphire display caseback, this anniversary example is fitted with the special “50 Years” rotor, exclusive to 2022 Royal Oak models and a key detail for collectors.
This 2022 example is offered as a complete full set and remains in very good condition, showing only minimal signs of careful use. It is an excellent opportunity to acquire a milestone Royal Oak chronograph that blends historical significance, cutting-edge engineering, and long-term collector appeal.
Complete Set Information
This watch is offered as a full set and includes the original Audemars Piguet inner and outer boxes, warranty card, instruction manual, and stainless steel Royal Oak bracelet. The watch features the exclusive 50th Anniversary rotor visible through the sapphire caseback. It is in very good pre-owned condition with light wear consistent with careful handling. The bezel and crystal are clean, and all functions operate as intended.
