Overview
Carbon TPT® case with a titanium crown and an unset dial centre
This execution pairs the Carbon TPT® case with titanium, and leaves the dial centre unset, so that the skeletonised CRMA1 and its two calendar discs are visible across the whole width of the movement.
The layered striations of the Carbon TPT® run across bezel and caseband, the crown and pushers are white metal, the inner bezel carries a gold-toned frame, and the strap is black rubber.

Design and engineering
- Carbon TPT®Layers of parallel carbon filaments no thicker than 30 microns, impregnated with resin and laid with the weft rotated between plies, cured under heat and pressure and machined on CNC at Richard Mille; no two cases carry the same figure.
- Unset dial centreThe openworked calibre is left visible rather than covered by a set plate — the only execution in this group with no stones at all.
- Oversize dateSemi-instantaneous, placed horizontally under 12 o’clock and driven by two skeletonised calendar discs over a white field.
- Function selectorA push-button at 4 o’clock selects winding, neutral and hand-setting with a single push, in the manner of a gearbox; an aperture alongside shows W, N or H. A second push-button at 10 o’clock corrects the date.
- Patented stem-crown assemblyThe crown is part of the case rather than the movement, so no classical crown attachment penetrates to the heart of the calibre. It is sealed with an Alcryn® O-ring and collar.
- Case productionThe empty case requires more than 255 tooling operations and over five hours of glazing and polishing at the final stage; the profile is cut on a five-axis machine, and the Richard Mille engraving on the inside curve of the caseback takes 45 minutes per case.
