Abstract

PURPOSE:To perform the correction of a long time on a watch in a short time by changing the speed of indicated time changing gradually for an indication device in accordance with the length of time to actuate a time correcting switch. CONSTITUTION:When a switch 8 to correct time is pressed down, a chattering prevention circuit 9 is actuated, and the reset signal to a counting circuit 7 is released, and output signals from a frequency dividing circuit 2 are counted. The output of the counting circuit 7 is decoded at a decoder 10 and the input to one of AND circuits 11, 12, and 13 is raised to a high level, and one of the signals of the frequencies f1, f2, and f3 of the frequency dividing circuit 2 is selected according to the time in which the switch 8 is pressed down and it is outputted from an OR circuit 14.
