Abstract

The watch-chronograph has two independent hands controlled by a motor. Under control of an electronic circuit the hands may indicate hours and minutes of the time of day, or minutes and seconds. A controller includes two push buttons for disconnection of spindle tops. This allows hour of the day or chronograph time to be shown instantly as required. Two short-lived supports are set on the second button. The watch-chronograph is set in an initial mode in which the two hands are set to a given initial position, especially a zero position. When this happens two counters are set to zero.
