Royal Oak Chronograph 26240

The Audemars Piguet Royal Oak Chronograph 26240 marks the next evolution of the iconic Royal Oak, celebrating the collection’s 50th anniversary with both subtle and meaningful updates. Collectors value this reference for its blend of classic Gerald Genta design cues—tapisserie dial, integrated bracelet, octagonal bezel—with the introduction of the in-house caliber 4401, which brings a flyback chronograph function for the first time to the standard Royal Oak Chronograph line.

Reference 26240 replaces the previous 26331, distinguished by its new movement, slightly reworked dial proportions, and a display caseback showcasing the movement and commemorative 50th anniversary rotor (on early production pieces). The 41mm case retains the familiar Royal Oak silhouette but offers a more refined, ergonomic fit. Dial variants—blue, black, silver, and boutique exclusives—drive price variation, with rarer dials and limited editions commanding premiums on the secondary market.

When considering a purchase, note that early 26240 models with the anniversary rotor are particularly sought after. The flyback chronograph and 70-hour power reserve add daily practicality to its appeal. Water resistance is rated to 50 meters, suitable for daily wear but not for swimming. Bracelet finishing, dial color, and completeness of box and papers all impact value; expect the blue dial to attract the strongest demand. This reference is already tightly held, so condition and provenance carry extra weight in negotiations.
