Abstract
An actuating element for the manual adjustment of a clock comprises a rotating collar face which is arranged around the time indicating device of the clock. In a mechanical or electromechanical clock, the rotating movement of the rotating collar face is transmitted through gearing to the dial train of the clock. In an electronic clock pulse-producing elements are arranged on the collar and pulse-receiving elements are fixed in the clock to produce individual pulses or pulse trains which can be counted in according to the backward counting input of the time storage which is in operative connection with the indicating element of the clock.
