It is the first Royal Oak Offshore with a case and bracelet made entirely of ceramic. This material is also used for the push-pieces at 2 and 4 o’clock that operate the chronograph, as well as for the screw-locked crown at 3 o’clock. Only the eight white gold screws attaching the bezel to the case stand out, along with the eight luminescent applied hour-markers that punctuate the hours and the titanium caseback. . This reference is powered by Calibre 4404, Audemars Piguet’s integrated chronograph movement with a flyback function.
