The Audemars Piguet Royal Oak Chronograph collection represents the evolution of what many consider the original luxury sports watch. Since Gerald Genta created the Royal Oak in 1972, AP has continued refining and expanding the line with new sizes, materials, and complications. These chronographs share the iconic octagonal bezel with hexagonal screws, integrated bracelets, and the distinctive Grande Tapisserie dial pattern that collectors instantly recognize. We’ve had the opportunity to check these out up close recently.

Audemars Piguet Royal Oak Chronograph 38mm Rose Gold Silver Dial Diamond Bezel 26715OR.ZZ.1356OR.01
The 26715OR proves that case diameter doesn’t tell the whole story. With a 48mm lug-to-lug measurement, this 38mm chronograph wears comparable to a Rolex Daytona, making it a legitimate option for men who prefer a smaller case or women who like something substantial.
- Case size: 38mm diameter, 48mm lug-to-lug
- Thickness: 11mm
- Material: Rose gold with diamond bezel
- Dial: Silver (or white)
- Updated case design with thicker beveled edge compared to previous reference 26315
This watch works for anyone wanting a true midsize Royal Oak chronograph, whether that’s a woman who appreciates larger watches or a man with a smaller wrist looking for proper proportions.

The 26240ST represents the complete redesign AP rolled out for the Royal Oak’s 50th anniversary in 2022. The reviewer notes that while everything looks more or less the same as the previous generation, the entire watch was revamped with numerous improvements in the details.

Audemars Piguet Royal Oak Chronograph Rose Gold Brown Index 41mm Brown Leather 26331OR.OO.D821CR.01
The 26331OR on leather showcases the Grande Tapisserie pattern in brown, which the reviewer highlights as a beautiful complement to the rose gold case. The sub-dials feature a matte center with high polish outer tracks, and the index markers provide green luminosity that glows well in the dark.

- Material: Rose gold
- Dial: Brown Grande Tapisserie pattern
- Strap: Brown leather
- Luminous index hour markers with dots behind them for dark readability
