RM 030 Automatic Winding with Declutchable Rotor

The RM 030 is distinguished by a smart declutching rotor technology. It is a derivative of the torque sensor the company has for their tourbillon watches. The RM 030 Automatic Winding with Declutchable Rotor represents real improvement in performance.

Richard Mille had long envisioned developing a declutching rotor mechanism, as a dynamic extension of the torque sensor currently found in our tourbillon clocks. Skeletonized automatic-winding movement with a power reserve indicator, hours, minutes, and seconds hands, as well as a declutchable variable-geometry rotor.
