1. A device for manually controlling a mechanism for a timepiece, comprising:
two counteracting manual corrector actuators, arranged to be operated by a user and to control one and the same correction wheel set in opposing movements, each of the two manual corrector actuators setting in motion an associated corrector having a beak which is configured to bear against a relief of said correction wheel set and to cause said correction wheel set to move when said manual corrector actuator is moved over its full path of travel under the action of the user, said manual control device comprises a locking lever mechanism arranged to prohibit an action of one of the two manual corrector actuators on said correction wheel set when the other of the two manual corrector actuators is engaged and interacting with said correction wheel set, wherein said locking lever mechanism comprises a locking lever configured to be driven in rotation during the engagement of one of the two manual corrector actuators, in order to limit the travel of the other of the two manual corrector actuators and to prevent the corrector associated therewith from accessing said correction wheel set,
wherein each of the two manual corrector actuators pivots about a hinge pin, and
wherein each associated corrector comprises an oblong guide groove cooperating with said hinge pin of the corresponding manual corrector actuator, said oblong groove being configured to guide the movement of said associated corrector during the pivoting of said corresponding manual corrector actuator.
