Richard Mille’s RM 07-01 Coloured Ceramics is the final chapter of this Richard Mille collection, and it is an interesting conversation starter
Richard Mille calling anything a “final chapter” deserves attention—after all, the watchmaker has built its entire business model on perpetual reinvention. The 2026 RM 07-01 Coloured Ceramics closes out a collection that started in 2021, and it does so with blush pink, lavender and powder blue TZP ceramic bezels set with diamonds, sapphires, rubies and tsavorites, and a total of 150 pieces across the three colours. Let’s discuss those new ceramic cases. TZP, or tetragonal zirconia polycrystal, constitutes over 95 per cent zirconia and rates 1,400 Vickers in hardness, making it exceptionally resistant to scratching while remaining lighter than steel on the wrist, at a density of around 6 g/cm. It is also, at that hardness rating, a material that defeats conventional cutting tools entirely—diamond tooling is the only means by which it can be machined into the compound curves the case demands. The mitraillage—the French term for the process of applying pavé style gem-setting to a surface by hand—requires gold prongs to be pressed into zirconia, adding to the difficulty of working with this material. The case, then, is not just a container for the movement beneath—it is an engineering undertaking in its own right.

Inside, the CRMA2 calibre is 4.92mm thick, skeletonised, slim and built in house at the Richard Mille manufacture, with a balance wheel that can be fine-tuned directly rather than relying on the traditional regulator found in most mechanical movements. The fast-rotating barrel completes one revolution every five hours rather than the standard 7.5, which flattens the mainspring’s torque curve and keeps energy delivery consistent across the 50-hour power reserve. The variable-geometry rotor, weighted with a 5N red gold ring and running on ceramic ball bearings, can be adjusted by shifting two weighted screws—this tunes how much winding momentum the rotor generates to suit whether the wearer leads an active lifestyle or a more sedentary one, ensuring the mainspring receives neither too much nor too little energy. The baseplate and bridges are grade 5 titanium, microblasted and electroplasma treated.

The dials combine several decorative techniques on a single surface: guilloché engraving, laser-cut rubber appliqués and diamond-set components within white gold inserts, all on a grey PVD-treated red gold base. Each guilloché pattern is traced by hand on a rose engine, requiring the craftsman to apply identical pressure across every single line to ensure a consistent finish. It is one of the oldest decorative techniques in watchmaking. For the collector who understands what they are looking at, the RM 07-01 Coloured Ceramics needs no closing argument. With 50 pieces per reference, three colours, and five years of technical and aesthetic refinement behind it, the watch has already made its case.
