Overview
ATZ white ceramic bezels on a titanium-coloured caseband
The white ceramic RM 30-01 uses ATZ, Richard Mille’s designation for white ceramic. The watch shows white ceramic front and back bezels over a caseband in a grey metal, fitted to a black vented rubber strap.
Mechanically it is unchanged from the rest of the reference: the calibre RMAR2 with its declutchable variable-geometry rotor, function selector, oversize date and clutch engagement indicator, visible through the sapphire dial and the sapphire caseback.
