Audemars Piguet launched the Royal Oak Chronograph Ref. 26315 in a unisex 38 mm. size in 2019 and was an instant hit because of its wearable size and proportions. The watch was available in steel (two references) and rose gold (one reference) and was powered by the same self-winding Cal. 2385 with an 18k gold rotor.
