Overview
ATZ white ceramic with a mother-of-pearl centre
The bezel and caseback are ATZ white ceramic, matte and hard-wearing, with white metal on the crown and pushers. The dial-centre plate is framed by two rows of stones around a mother-of-pearl panel.
Case, setting, nacre and strap sit within a narrow tonal range, so the openworked calibre visible around the centre plate provides the contrast.

Design and engineering
- ATZ white ceramicRichard Mille’s designation for white ceramic, matte in finish and highly scratch resistant.
- Mother-of-pearl dial centreA nacre panel cut and set into the centre plate; the material’s layered structure produces the iridescence, so the play of light shifts with the angle of the wrist.
- Two set rowsThe dial-centre plate is framed by two rows of stones rather than a single row or a paved field.
- Oversize dateSemi-instantaneous, placed horizontally under 12 o’clock, 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; an aperture at 4 o’clock 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, sealed with an Alcryn® O-ring and collar, so no crown attachment penetrates to the calibre.
