A timepiece display mechanism with an instantaneous jump function, including a Maltese cross mechanism with an annular ring controlling, in part of its travel, the pivoting of a planet wheel set and driven by a timepiece movement via a cam wheel set arranged to move the annular ring from an activated position to a deactivated position in an instantaneous displacement in order to pivot a planet wheel set, and vice versa in a controlled return slower than the instantaneous displacement, the cam wheel set includes a coaxial cam and plate including a slot for driving an eccentric finger of the cam which controls the pivoting of a driver driving the annular ring between two extreme activation and deactivation positions, the slot allowing a clear jump of the driver in the deactivation position, and a longer reactivation time.
