Abstract

PURPOSE:To achieve the improvement in the performance of the electronic watch by enabling one-touch correction of AM and PM to be performed with an external switch at the time of time correction. CONSTITUTION:When a switch 14 is turned ON while a display mark AM is lighting as the signal of 1 is outputted from the output terminal Q of a T-flip-flop, the signal of 1 passes through an OR gate 17 and is inputted to the T-flip-flop. And the output signal from the output terminal Q changes from 1 to 0 and the signal of 1 is outputted from the output terminal Q, then a display mark PM is lighted. Next, when the switch 14 is tured ON from this state, the signal of 1 passes through the OR gate 17 and is inputted to the T-flip-flop. At this time, the output signal from the terminal Q changes from 1 to 0, then the display mark PM goes off and the signal of 1 is outputted from the output terminal Q . The display mark AM then goes on.
