Overview
A rotor that disengages itself when the mainspring is fully wound
The RM 030, introduced in 2011, carries a rotor that declutches automatically. When the power reserve reaches 50 hours, a purpose-built gear system disconnects the rotor from the winding barrel; when the reserve falls back to 40 hours, the rotor re-engages and a new winding phase begins. The wearer can follow those phases on the winding indicator at 12 o’clock, which reads on or off.
Richard Mille describes the system as a dynamic continuation of the torque sensor developed for its tourbillon watches, applied here to an automatic movement, and took four years to develop the concept. The purpose is to hold the mainspring at an ideal tension so that the movement and the oscillator work at the best constant torque-to-power ratio.
Key details
Design and engineering
- Declutchable rotorThe rotor disengages from the barrel at 50 hours of reserve and re-engages at 40, which prevents the mainspring being held at full tension and keeps torque delivery in its best range.
- Winding indicatorAt 12 o’clock, reading on or off according to whether the rotor is currently clutched.
- Four years of developmentThe concept and design of an automatically declutching rotor took four years, and the miniaturisation was the harder half of the problem.
- Titalyt®-treated titanium movementBaseplate, bridges and balance-cock in grade 5 titanium, wet sandblasted and Titalyt® treated; barrel bridges PVD coated.
- Case machiningThe case requires 86 preparatory operations, including 49 striking operations, before cutting and milling of the bezel, case middle and back can begin.
- Movement mountingNo casing ring. The movement sits on chassis mounting rubbers (ISO SW) fixed by four grade 5 titanium screws.
