A REVOLUTIONARY ASSERTION OF THE BRAND’S GRAMMAR
RM 010 AUTOMATIC
Skeletonised automatic winding movement with hours, minutes, date and variable-geometry rotor.
Circa 55 hours (± 10%).
BASEPLATE AND BRIDGES MADE OF GRADE 5 TITANIUM
The baseplate and the bridges are crafted of grade 5 titanium, a biocompatible, highly corrosion-resistant and remarkably rigid alloy, which enables the gear train to function effortlessly.
The alloy is 90% grade 5 titanium, 6% aluminium and 4% vanadium. This combination further increases the material’s mechanical properties, which explains its frequent use in the aerospace, aeronautics and automobile industries.
The skeletonised baseplate and bridges have been subjected to intensive and complete validation tests to optimize their resistance capacities.
Semi-instantaneous, placed in a vertical aperture at 7 o’clock. The calendar disc of sapphire crystal is treated with nonreflective coating on both sides.
The Richard Mille RM 010 uses a variable geometry system to optimise the rotor’s winding motion.
• Arm in grade 5 titanium
• High palladium content 18K white gold weight segments
• Weight segment with 6 possible positions adjusted by screws in grade 5 titanium
• Ceramic ball bearings
• Unidirectional, anti-clockwise winding direction
This exclusive Richard Mille design makes it possible to effectively adapt rewinding of the mainspring to the user’s activity level, in sporting or non-sporting environments. By adjusting the six-position rib, the rotor’s inertia is modified to either speed up the winding process in the case of leisurely arm movements, or to slow it down during sporting activities.
As a result, this invention allows the movement’s winding mechanism to be optimised and personalised to the owner’s lifestyle.

In order to produce each case, 68 different stamping operations are required for the three main components (bezel, caseband and caseback). The machine tooling process requires 8 days of adjusting the machines for the bezel, 5 days for the middle section and 5 days for the caseback. Prior to this process, developing a methodology for carrying out this series of operations took 120 hours, the drawings for the tools 130 hours, and implementation 180 hours.
Each rough case involves 202 separate machining operations. The design and execution of the watch demonstrate a holistic approach to conception of the movement, case and dial.
The tripartite case is water resistant to 50 metres, ensured by 2 Nitrile O-ring seals and is assembled using 12 spline screws in grade 5 titanium and abrasion-resistant washers in 316L stainless steel.
