Richard Mille RM 07-01 ‘Ladies’ Black Ceramic Rose Gold Diamond-Set Skeleton Dial (2020)

The RM 07-01 stands as Richard Mille’s principal ladies’ reference, conceived to translate the engineering language of the men’s tonneau collection into the smallest case proportions in the catalog. The black TZP ceramic execution represents one of the more technically demanding configurations to produce — the material’s 1,400 Vickers hardness and superior toughness to sapphire require lengthy diamond-tool machining to shape the complex case geometry. Paired with a rose gold dial framework and diamond-pavé cartouche over a deep blue baseplate, this configuration occupies the intersection of advanced materials science and high jewelry that has defined Richard Mille’s appeal among women collectors of contemporary haute horology.

The tonneau case measures 45.66 x 31.40 x 11.85mm in microblasted black ceramic with rose gold caseband, secured by twelve grade-5 titanium spline screws. The skeletonized dial features a central rose gold diamond-pavé cartouche framing the hours and minutes hands, set against a blue baseplate that reveals the openworked Caliber CRMA2 beneath. Built on a grade-5 titanium baseplate with electroplasma treatment, the automatic movement features a variable-geometry rotor with 5N red gold segments and delivers a 50-hour power reserve, completed by a black rubber strap.
