The Audemars Piguet Royal Oak Selfwinding Chronograph ref. 26240ST.OO.1320ST.04 is a 41 mm stainless-steel chronograph distinguished by its khaki “Grande Tapisserie” dial and integrated steel bracelet. The octagonal bezel, exposed screws and alternating brushed and polished surfaces preserve the architectural character that defines the Royal Oak, while the three-register chronograph layout gives this reference a more technical presence than the time-only versions of the collection.
The watch is powered by Audemars Piguet’s integrated automatic chronograph architecture, combining central chronograph seconds with elapsed-time counters and a date display. Through the sapphire caseback, the special “50-years” oscillating weight identifies this execution as part of the Royal Oak’s 50th-anniversary generation.
Reference 26240ST.OO.1320ST.04 is particularly distinctive because it pairs the modern 41 mm Royal Oak Chronograph platform with a khaki dial, creating a less conventional alternative to the collection’s blue, black and silver configurations. Its combination of integrated-bracelet design, chronograph functionality and anniversary-specific detailing makes it a notable contemporary Royal Oak reference.
