The Royal Oak Offshore Diver has seen a number of cool and high-tech iterations. It started with a basic 42 mm wide model in steel, unsurprisingly, but that was followed up with variants in carbon composite cases with ceramic bezels, and subsequently even cases entirely in white or black ceramic. All these three-handed versions are powered by the beautifully finished, in-house caliber 3120 movement that features a solid gold rotor sporting the Audermars and Piguet families’ coat of arms.
