Released in 1972 and designed by Gerald Genta, watchmaking's most famous designer, the Audemars Piguet Royal Oak was the first stainless steel luxury sports watch ever to exist. Released as a tactic to survive the quartz crisis, the Royal Oak can single-handedly be thanked for AP's existence today due to its astounding success, albeit it wasn't an overnight hit. Its sizeable tonneau-shaped case, signature integrated bracelet, octagonal bezel, exposed screws, and steel construction failed to win over collectors until a few years later. Today, the Royal Oak is one of the most highly-coveted timepieces in all horology as its previously dismissed design details have permeated across the industry and into watches like the Patek Philippe Nautilus, Vacheron Constantin Overseas, Rolex Oysterquartz, amongst many other legendary timepieces.

Launched in 2022 as part of the Royal Oak’s 50th anniversary releases, the new Royal Oak Chronograph ref. 26715ST.OO.1356ST.01 is a subtly improved version of the Royal Oak Chrono that proves watchmakers don’t need to make sweeping changes to improve their watches. Indeed, this new reference, the ref. 26715ST, features a new dial design with new hour markers to give uniformity to the collection, a new blue dial color, as seen on our example here ("Bleu Nuit, Nuage 50"), that is as close to the original Royal Oak as AP could have made it. However, some small changes have also been made that differentiate its design from the original, like the removal of AP’s “AP” logo at 12 o’clock which gives the dial more space to breathe resulting in a less cluttered look. Measuring 38mm in diameter, the ref. 26715ST introduces a new case size to the Royal Oak Chronograph family that collectors are sure to love given its universal wearability and similarity to the original 39mm Royal Oak “Jumbo” from 1972.
