Abstract
A timepiece torque variator mechanism regulates the torque ratio between a first path extending about a first pivot axis and a second path about a second pivot axis. The mechanism includes a planetary element that simultaneously cooperates in a first contact area with a first path and in a second contact area with a second path. The mechanism also includes a control device arranged to adjust the radial position of the first contact area with respect to the first pivot axis and/or to adjust the radial position of the second contact area with respect to the second pivot axis.
