A date adjusting mechanism for a timepiece includes a date ring and an operating shaft mounted for axial and rotational displacement. The shaft is axially shiftable into and from a date control position. A date control gear is mounted on the shaft. A correcting gear is continuously connected to the date control gear. The correcting gear is shiftable toward and away from driving engagement with the date ring. A stop lever is rotatably mounted to the frame of the time piece. Linkage is provided for connecting the stop lever to the operating shaft to rotate the stop member into a position blocking movement of the correcting gear into driving engagement with the date ring when the operating shaft is axially displaced from its date control position.
