Abstract
A display mechanism including a mechanism for fast correction of a position of a display wheel set, an intermediate wheel set ensuring synchronization with an automatic drive mechanism, and, inserted between the intermediate wheel set and the display wheel set, a safety lever driven by the display wheel set during periodic driving thereof, in a trajectory that interferes with a spatial volume of the intermediate wheel set, such that, when the intermediate wheel set is correctly synchronized, the trajectory of the lever does not interfere with the intermediate wheel set, and, when the intermediate wheel set is not correctly synchronized, the trajectory of the safety lever interferes with the intermediate wheel set, which the safety lever then drives in an opposite direction to a single direction of normal operation, to resynchronize the intermediate wheel set.
