Overview

The Audemars Piguet Royal Oak Selfwinding Chronograph 38 (ref. 26315ST) brings the iconic octagonal bezel and Grande Tapisserie dial of the Royal Oak family to a 38 mm stainless steel case, a size that sits comfortably between the line's larger sport-chronograph offerings and its dress-watch roots. Introduced in 2019, it houses Calibre 2385, an integrated self-winding chronograph movement that reflects AP's long commitment to in-house complications. Dial variants in silver, blue, and black give collectors meaningful choice within a single reference.

History

The Royal Oak line was conceived by Gérald Genta and launched by Audemars Piguet in 1972 as a luxury sports watch in stainless steel — a radical proposition at the time. Chronograph versions of the Royal Oak have been part of the collection for decades, evolving through successive calibres and case sizes. The 38 mm format of the 26315ST, introduced in 2019, responded to collector demand for a chronograph that retained the full Royal Oak aesthetic without the larger footprint of earlier references. Its availability in multiple dial colours has made it one of the more versatile entries in the contemporary Royal Oak chronograph range.

Notable points

38 mm stainless steel case with the Royal Oak's signature eight-sided bezel secured by eight hexagonal screws.
Calibre 2385 is an integrated self-winding chronograph movement, continuing AP's tradition of purpose-built in-house ebauches.
Grande Tapisserie dial — the finely chequered guilloché pattern synonymous with the Royal Oak — is offered in silver, blue, and black variants.
The 38 mm diameter positions the reference as one of the more accessible Royal Oak chronograph sizes, appealing to a wide range of wrist sizes.
Introduced in 2019, the reference remains in active production, reflecting sustained collector and market interest.
