Richard Mille adds to its Ladies’ collection an exclusive gem-set black ceramic model in the new RM 07-01 for Ladies in Gem-Set Black Ceramic will be on view for a sneak peek at the Salon International de la Haute Horlogerie in Geneva, next January.

In addition to its exceptional hardness and scratch resistance, black TZP ceramic possesses an extremely fine grain, ensuring a perfect finish with a matte effect. The latter is the outcome of a long and delicate process of milling and micro-shot peening, whereas showcasing the complex shapes of the bezel and case bottom requires the intervention of a finisher, who polishes each angle by hand.

“After our work on setting gems in Carbon TPT®, we wanted to extend this innovative setting technique to new materials”, explains Cécile Guenat, Technical Director for Jewellery-making at Richard Mille. “We naturally gravitated to ceramic, because it had never been done before. There is now no subterfuge in the way diamonds are incorporated, thanks to way the mitraillage is performed by machining the material directly.”

Separately produced, and carefully polished to ensure a perfectly even feel, red gold prongs are embedded in the many settings, each 0.25 millimetre in diameter, receiving and holding fast the diamonds placed by the gem-setter. These are full-cut stones, selected for their exceptional clarity.

The timpeiece houses the in-house Calibre CRMA2, an automatic movement assembled on a baseplate and bridges crafted in grade 5 titanium. Its variable-geometry rotor in 18-carat. At the heart of this calibre, 5N red gold makes it possible to adjust the automatic winding to the activity levels of its wearer.
