The winding of an automatic wristwatch is accomplished by a small turning rotor, silently driven as a result of the physical movements of the wearer. These rotations of the rotor provide energy to the winding barrel, which reaches its optimal point once it is fully wound. After this point, overwinding can easily occur and needs to be avoided. This is traditionally achieved through the use of a sliding flange that allows the spring to slip, thus avoiding the movement becoming overwound. However, this traditional system allows the build-up of harmful debris inside the winding barrel as the flange releases the excess energy of overwinding during longer periods, especially when a person is particularly active. This in turn can severely affect chronometric results. To avoid such adverse conditions, Richard Mille took four years to develop the concept and the design of a rotor that declutches automatically. With this system, the winding barrel is automatically disconnected from the rotor's winding mechanism at the moment when the spring is fully wound. Additionally, this new mechanism is linked to the power reserve indicator to provide an optimal winding control. This allo
