The ten variations of this watch are available exclusively at Richard Mille boutiques worldwide. Each variation is a seven-piece limited edition.
Technical Specifications:
IN-HOUSE CALIBRE CRMT1: Skeletonised automatic-winding tourbillon movement with hours, minutes and variable-geometry rotor. Case dimensions: 52.20 x 34.40 x 12.50 mm
POWER RESERVE Circa 50 hours (±10%)
BASEPLATE AND BRIDGES MADE OF TITANIUM
Microblasted grade 5 titanium with PVD treatment lends great rigidity to the baseplate and the bridges, as well as the precise surface flatness essential for perfect functioning of the gear train. The skeletonised baseplate and bridges were subjected to intensive and complete validation tests to optimise their resistance capacities.
GEM-SET VARIABLE-GEOMETRY ROTOR
The RM 71-02 uses variable geometry to optimise the rotor's winding motion.
Rotor specifications: - Heavy outside edge and heavy edge ring in 5N red gold - Weight segment in heavy metal - 18K white gold wings - Ceramic ball bearings - Automatic OneWay® winding system in ceramic with ball bearings - Bidirectional winding system
This variable-geometry rotor has been incorporated within the in-house CRMT1 calibre, making it possible to set the rotor according to the owner's activity level. The setting is modified by adjusting the two moveable weights into the correct position and fixing them in place with spline screws. The inertia of the movement is increased when the two weights are closer together; the barrel then rewinds more quickly. If the weights are positioned at the extremities of the rotor, the inertia is decreased and the barrel winds more slowly.
FREE-SPRUNG BALANCE WITH VARIABLE INERTIA
This type of balance wheel represents the ultimate in innovation. It guarantees greater reliability when subjected to shocks and during movement assembly or disassembly, hence better chronometric results over time. The regulator index is eliminated, and a more accurate and repeatable calibration is possible thanks to 4 small, adjustable weights located directly on the balance.
FAST-ROTATING BARREL (5 HOURS PER REVOLUTION INSTEAD OF 7.5 HOURS)
This type of barrel provides the following advantages: - The phenomenon of periodic internal mainspring adhesion is significantly diminished, thereby increasing performance, - Provision of an excellent mainspring delta curve with an ideal power reserve/performance and regularity ratio.
GEAR TEETH PROFILE
The entire going train of the watch, the primary transmitter of power throughout the movement, utilises a special profile for the teeth of the wheels that ensures a 20° pressure angle. This system equalises any discrepancies that might arise among the centres of the various wheels, for instance due to thermal changes and normal use, and promotes the smooth transmission of torque to the balance wheel, thus supporting excellent chronometric results.
SPLINE SCREWS IN GRADE 5 TITANIUM FOR THE BRIDGES AND CASE
This permits better control of the torque applied to screws during assembly. These screws are unaffected by physical manipulation during assembly or disassembly and age well.

WHITE GOLD CASE
The design and execution of the watch demonstrate a holistic approach to conception of the movement, case and dial. As a result, everything has been constructed according to extremely rigorous specifications. The case, crafted in white gold, is composed of 75% gold, 4% silver and a high palladium content of 17% to provide white brilliance.
No less than 44 different stamping operations are required for the three main components of the case (bezel, caseband and caseback). The machine tooling process requires 2 days of adjustment for each component (bezel, caseband and caseback). The empty case involves over 255 tooling operations and more than 5 hours of glazing and polishing for the final phase. The complex shape of the case is obtained thanks to a 5-axis machine.
The 10 variations on the snow and grain settings bring together different textures, diameters and faceting, achieving freedom of expression all over the front bezel and caseband, whereas the caseback is engraved with matt bands.
The tripartite case is water resistant to 50 meters, ensured by 2 Nitrile O-ring seals. The case is assembled with 20 grade 5 titanium spline screws and abrasion-resistant washers in 316L stainless steel.
RED AND WHITE GOLD DIALS SET WITH GEMS
Each dial, a mere 0.9 mm in thickness, is handset with ornamentals and coloured stones. This component is an immense technical challenge because of the many different finishing operations required: sandblasting, polishing, setting... and all this in a very small area arranged on several levels. The dials draw on two distinct universes: one more plant-based and the other more urban.
