Device for manually controlling a mechanism for a timepiece

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 said locking lever constitutes a safety lever, said locking lever comprising a first end having a first stop finger and a second end, opposite the first end, which has a second stop finger, the first and the second stop fingers being configured to cooperate in abutment, respectively with a manual corrector actuator from among the two manual corrector actuators, and
• wherein each of the two manual corrector actuators comprises:
• a first bearing profile configured to form a stop profile in cooperation with the first stop finger or the second stop finger and to prevent said manual corrector actuator considered from rotating;
• a second bearing profile configured to form an escapement profile on which the first stop finger or the second stop finger slides so as to allow said manual corrector actuator considered to partially rotate.
