Abstract (en)
[origin: CN112925186A] The invention relates to a timepiece display mechanism (1) with an instantaneous jump function. The timepiece display mechanism (1) comprises a Maltese cross mechanism with an annular ring (10) controlling, in part of its travel, the pivoting of a planet wheel set (300) and driven by a timepiece movement via a cam wheel set (456) 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 (456) includes a coaxial cam (16) and plate (15) including a slot (151) for driving an eccentric finger (160) of the cam which controls the pivoting of a driver (17) 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.
