Abstract
A timepiece display mechanism with a resilient hand including a first and second device for driving, about an output axis, a first and a second pipe mounted at the ends of a flexible strip, and including a display index distant from the pipes, these drive devices being arranged to deform the flexible strip, by varying the angular position of one pipe with respect to the other about the output axis, and to vary the radial position of the display index with respect to this axis, this mechanism includes a first differential on the drive train of the first pipe, one input of which is formed by a first cam, and a second differential on the drive train of the second pipe, one input of which is formed by a second cam.
