The Royal Oak Perpetual Calendar Openworked exemplifies exceptional technical prowess, featuring a striking black ceramic case that frames an intricate open-worked sapphire dial. The movement’s visible pink gold components contrast beautifully against the black ceramic, enhancing the watch’s artistic appeal. This 41 mm timepiece is equipped with a glare-proofed sapphire crystal, case back, and a screw-locked crown for added durability. The sapphire dial showcases a smoked external zone around the counters, pink gold applied hour-markers, and Royal Oak hands with luminescent coating. The watch has a black ceramic bracelet and a titanium AP folding clasp.
