The 41mm Royal Oak Selfwinding Chronograph is now equipped with the latest generation of the in-house integrated flyback chronograph, self-winding Caliber 4401. Two years ago, Audemars Piguet introduced that milestone movement with the debut of the CODE 11.59 collection, and now it has made its way into Royal Oak.

For the first year, it will be limited to a pair of 18-karat rose-gold models—one with a blue dial and one with a brown dial, either on strap or gold bracelet (US$45,800 on strap, US$66,300 on bracelet). The new in-house chronographs will hit the market in May.
