Overview
The Mask in a transparent brown case
The case is brown sapphire throughout, so the mask and the eight bridges carrying it to the caseband can be read from the flanks as well as through the front and back. The strap is white.
The mask remains a working component rather than an ornament: it serves as the wheel-train and tourbillon bridge, with the back of it acting as the movement’s centre bridge.

Design and engineering
- Brown sapphire caseMilled and ground from blocks of coloured synthetic sapphire, a material rating 1,800 Vickers and effectively scratch-proof except by diamond. Breakage through the process is common enough to account for much of the cost.
- Mask as componentServing as the wheel-train and tourbillon bridge rather than sitting over the movement, with the back of the mask performing the function of the centre bridge.
- Eight connecting bridgesConnecting the mask to the case and visible from the back, all grade 5 titanium and all created from a single block.
- Microblasted surfaces with polished anglageMicroblasted surfaces accentuated by polished anglage, which emphasises the protruding edges of the mask.
- An open readingRichard Mille leaves the reading open — a luchador, a kabuki mask, a superhero, a gladiator helmet — and describes it as a Rorschach test.
- Manual-winding tourbillonHours and minutes.
