Abstract
A chronograph watch comprises a first motor controlled by a quartz resonator coupled to a first simple integrated circuit. This motor drives, through gearing, the time indicating members of the watch. A second motor controlled by a second quartz resonator coupled to a second simple integrated circuit, identical to said first integrated circuit, can be operated at a higher frequency when a switch, which is operable manually by means of a pushbutton and interposed between electrical ground and a terminal of the second integrated circuit, is open. The second motor drives, through further gearing, a chronograph hand coupled to a minute counter and to an hour counter. Thus the chronograph indicates fractions of seconds without the timepiece requiring expensive circuits or having an excessive electrical power consumption.
