The watch comprises a plurality of stores, each containing a particular item of time data and each producing an output signal representing the data therein. A single operating button is displaceable by the user of the watch, on the one hand in the axial direction between a pushed-in position and a pulled-out position for which a switch is respectively open and closed, and on the other hand rotatably. Rotation of the button closes and opens two more switches by two cams rotationally displaced so that two pulse trains are produced with a phase relationship indicating the sense of rotation. A circuit processes these pulse trains to produce UP pulse for one sense of rotation and DOWN pulses for the other sense of rotation. These pulses are used to correct the value in a selected store. The particular store to which the correction signal is applied is selected by axially displacing the operating button from the pushed-in position to the pulled-out position a predetermined number of times. A store selection circuit includes a counter which counts the pulls and selects the store in accordance with its count. The stores are divided into a first group comprising the hour of the day store, the minute of the hour store, the day of the week store and the day of the month store and a second group comprising the alarm hour setting store and the alarm minute setting store. First selecting means in the circuit make possible the selection of one or other of the two groups of stores in response to rotary displacement of the button while still pushed in and seocnd selecting means including the counter than make it possible to select one store from the selected group in accordance with the number of times the button is pulled out.
