Richard Mille RM30 ‘Argentina’
Powered by the new automatic Caliber RMAR1, which features a so-called “declutchable” winding rotor. As most watch savants know, the movement of an automatic wristwatch uses a small, turning rotor, activated by the motions of the watch’s wearer, to transmit energy to the winding barrel. However, it is easy to overwind the watch’s mainspring after it reaches its optimal point. Caliber RMAR1, with a rotor that declutches automatically, meaning that the winding barrel is automatically disconnected from the rotor’s winding mechanism at the moment the spring is fully wound. Additionally, this new mechanism is linked to the power reserve indicator, which helps to provide ideal winding control. This allows both the movement and the oscillator to work with the best ratio of constant torque/power to provide the best chronometric performance.
