ABSTRACT:
A calendar watch has rotatable date and day wheels each having teeth therearound. A winding stem is mounted on the watch for axial sliding movement and rotational movement and a correcting wheel is mounted for axial sliding movement on the winding stem. The correcting wheel has a first set of teeth engageable with teeth on the date wheel when the winding stem is moved to one axial position for effecting rotational movement of the date wheel to thereby make a date correction in response to turning of the winding stem in one rotational direction. The correcting wheel has a second set of teeth engageable with teeth on the day wheel when the winding stem is in the same axial position for effecting rotational movement of the day wheel to thereby make a day correction in response to turning of the winding stem in the other rotational direction.
