Abstract

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.
