ABSTRACT:
An electronic watch having a circuit for permitting it to be stopped in a state of minimum consumption. The watch has an oscillator, a frequency divider comprising flip-flops and a display, with the display and at least some of said flip-flops being connected to a common line so that a signal applied to the common line places them in a state of minimum consumption. The circuit including a switch connected between the common line and a terminal of the power supply and at least two MOS transistors connected so as to apply the signal to the common line when the switch is closed.
