Overview
The Audemars Piguet Royal Oak Chronograph 41 reference 26320ST represents the penultimate generation of the iconic integrated-bracelet chronograph in stainless steel. Powered by the in-house Calibre 2385 and housed in a 41 mm octagonal case, it occupies a pivotal position in the Royal Oak lineage. The Grande Tapisserie dial — available in blue, black, silver, and white — delivers the textural depth that has defined the Royal Oak aesthetic since Gerald Genta's original 1972 design.
History
Produced from 2012 to 2017, the 26320ST succeeded earlier 39 mm Royal Oak Chronograph references and marked Audemars Piguet's commitment to the now-standard 41 mm case size for the chronograph line. Its five-year production run coincided with a period of intense collector interest in the Royal Oak family, cementing the reference's status as a transitional milestone before the subsequent generation arrived. Today the 26320ST is regarded by collectors as a refined, slightly understated chapter in the Royal Oak Chronograph story.
