The Richard Mille RM 056 Jean Todt Edition is a highly exclusive luxury timepiece featuring a 50mm case crafted entirely from solid blocks of synthetic sapphire. This transparent construction is achieved through a specialized manufacturing process requiring approximately 1,000 hours of machining and 350 hours of polishing per case. The watch utilizes a manual-winding tourbillon movement and is distinguished by its skeletonized design, which extends the use of sapphire to the baseplate and central bridges, providing an unobstructed view of the internal mechanics from all angles.
The movement incorporates several sophisticated complications, including a split-seconds chronograph with a 30-minute totalizer, a power reserve indicator, and a torque indicator. It also features a function selector that allows the wearer to switch between winding, neutral, and hand-setting modes, similar to a car’s gearbox. The caliber is built with grade 5 titanium parts to maintain structural integrity while minimizing weight, and the case is secured by 24 spline screws in grade 5 titanium to ensure a water resistance of 30 meters.
General reviews of the RM 056 highlight its status as a pinnacle of horological engineering and material innovation, often praising the “visual lightness” and the “spectacle” of its entirely transparent assembly. Critics and enthusiasts note that while the watch’s aesthetic can be polarizing—with some comparing its appearance to high-end plastic—the technical difficulty of drilling and milling sapphire crystal is immense. Its extreme exclusivity, often limited to just a few pieces, and its multi-million dollar price tag position it as a significant status symbol within the collector community.
