  • Electronic watch movement
    Patent number: 4372689
    Abstract: A device for supplying the watch movement which comprises a time base (1) and a frequency divider (2) producing at least two signals (c), (d) at different frequencies. The two signals supply a logic selection device (3) of which the output supplies the circuit (5) for controlling the display of the timepiece movement.An actuating device (4) controls the selection device (3) in such a way that a pulse in the supply voltage causes the circuit (5) for controlling the display to be supplied by one signal (c) or the other signal (d) of the frequency divider (2) and thus causes the display to operate at different speeds.
