A watch with a calendar display and a hand setting device actuated by a setting shaft for correction measures as a function of the instantaneous position of the setting shaft is disclosed. For this purpose, a coupling element is rotatably coupled with the setting shaft. The coupling element is displaceable from an intermediate position into one of two preparatory positions dependent upon the direction of rotation of the setting shaft in a first axial position. By moving the setting shaft into a second axial position, the coupling element is transferred by a reversing lever and a slotted link from the preselected preparatory position into a corresponding one of two stable working positions. In the working positions, a rotatable connection is established between the setting shaft and one of the calendar display disks. With a further axial displacement of the setting shaft, the coupling element is returned into the intermediate position and a rotatable connection is established between the setting shaft and a minute hand correcting tube.
A watch with a calendar display and a hands setting device, comprising a setting shaft having a plurality of axial positions, the calendar display and the hands setting device being selectively coupled for rotation with the setting shaft as a function of the instantaneous axial position of said setting shaft, the setting shaft is drivingly connected during the transition from a first preselection axial position into a second calendar correction axial position through a reversing lever with a coupling element that may be rotated into one of two preselectable working position, the setting shaft is rotatably connected in the first preselection axial position with the coupling element to move the coupling element to one of two preparatory positions for the two working positions dependent upon the direction of rotation of the setting shaft, the setting shaft being rotatably disengaged from the calendar display in the first axial position, a slotted link acting on the coupling element during movement of the shaft from the first to the second axial position to urge the coupling element into the preselected working position in engagement with either a date display disk or a day-of-the-week display disk, a third axial position of the setting shaft for the setting of the hands, the coupling element being returned by the slotted link into an intermediate position and held between the two preparatory positions in the third axial position, and the setting shaft being rotatably connected with the minute hand in the third axial position through a hand setting wheel displaceable along an axis of the wheel in a direction transverse to a longitudinal axis of the setting shaft.
