In 2004, Richard Milleintroduced its firstautomatic, the RM 005 withsemi-instantaneous date-change.
This model also inaugurated the exclusive variable-geometry rotor, an invention that allows the movement’s winding mechanism to be optimised and personalised to the owner’s lifestyle.
Automatic movement with hours, minutes, seconds, date and adjustable rotor geometry.

This was the subject of an entire year of research and development. With regard to the production of each case, 68 different stamping operations are required for the three main components (bezel, middle section and case back).
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 case back.
For example, a casing ring is no longer used and the movement is mounted on chassis mounting rubbers (ISO SW) fixed by 4 titanium screws. Features such as these are evidence of uncompromising workmanship.
The tripartite case in platinum is water resistant to 100 meters, ensured by three Nitril O-ring seals.
The case is assembled with 12 spline screws in grade 5 titanium and abrasion resistant washers in copper-nickel-zinc alloy.
Skeletonised automatic movement with hours, minutes, seconds, date and adjustable rotor geometry.

This exclusive Richard Mille design allows the rewinding of the mainspring to be adapted most effectively to the user’s activity level within sports or leisure environments.
Baseplate, bridges and balance cock made of titanium
The manufacture of these components in grade 2 titanium with black PVD coating allows the whole assembly to be given great rigidity, as well as precise surface flatness which is essential for the perfect functioning of the gear train.
Spline screws in grade 5 titanium for the bridges and case
This permits better control of the torque applied to the screws during assembly. These screws are therefore unaffected by physical manipulation during assembly or disassembly and age well.
Semi-instantaneous, placed in a vertical aperture at 7 o’clock. The calendar disc of sapphire crystal is treated with non-reflective coating on both sides.

Double barrel system
The double barrel system helps improve torque stability over a longer period. This is achieved by using more turns, thereby reducing pressure and friction on the teeth, the bearings and the pivots, resulting in improved long-term performance.
