Abstract
A movement for a timepiece having a retrograde display member displaying at least one time division, includes a going train, elements for driving the display member including a wheel unit driven by the going train and carrying a first cam sharing the same axis of rotation. The movement also includes a rocker supporting a probe held against the edge of the first cam by deformable elastic elements undergoing a deformation of variable amplitude. This results in the application of a corresponding force on the rocker in proportion to the distance between the probe and the axis of rotation of the first cam. The movement also includes drive members to connect the rocker to a retrograde display member. A force-regulating device is interposed between the elastic elements and the rocker.
