Movement for timepiece with retrograde display

A display module for timepiece movement designed to drive a retrograde display member displaying at least one time division, comprising a frame supporting

• means for driving said retrograde display member comprising a wheel unit designed to be driven from a going train of the clockwork movement and supporting a first cam, sharing an axis of rotation with said wheel unit in reference to said frame,
• a lever supporting a feeler-spindle arranged so as to bear against the periphery of said first cam under the effect of deformable elastic means undergoing a deformation of variable amplitude, causing the application of a corresponding force on said lever, depending on the distance separating said feeler-spindle from said axis of rotation of the first cam, transmission means designed to connect said lever to said drive means,
• wherein a regulating device of said force is inserted between said elastic means and said lever.
