ABSTRACT:
A watch contains a date indicator ring and a day of week indicator ring. A switching wheel is displaceable selectively into meshing engagement with the indicator rings to effect adjustment thereof. The switching wheel is actuated by a shaft which is axially displaceable between selection and working positions. In its selection position, the shaft can be rotated in either direction to selectively place the switching wheel in one of two preliminary locations corresponding to a date ring adjustment location and a day of week ring adjustment position. By then axially displacing the shaft to its working position, the switching wheel is displaced to a final location to effect the previously selected mode of adjustment. Such adjustment is effected by rotating the shaft in either direction to rotate the respective indicator ring in either direction.
