PROBLEM TO BE SOLVED: To provide a device for the locking and unitary incrementation of a drive module (1) for a timepiece gear train. SOLUTION: The module (1) includes an actuator (2) fitted with an active click (5) cooperating with a toothed wheel (7), and the device includes a first (8) and a second (9) finger cooperating with the toothed wheel (7). The device is characterized in that the first finger (8) entirely locks the rotation of the toothed wheel (7) when it is engaged in one of the teeth of the toothed wheel (7); and in that the second finger (9) is arranged between a first (10) and a second (11) stop member, the space between the stop members (10, 11) limiting the angular travel of the toothed wheel (7) when the second finger (9) is engaged in one of the teeth of the toothed wheel (7).
