The Royal Oak 26540OR.OO.A010CA.01 was introduced in 2016. It is powered by caliber 2897, which pairs a tourbillon escapement and a chronograph complication - a combination that's very emblematic for Audemars Piguet. The rose gold case measures 44mm across and features a white ceramic screw-down crown and matching pushers.
Selfwinding tourbillon chronograph movement developed by Renaud & Papi, launched in 2011. Total of 335 parts.
