Abstract

PURPOSE: To make small the size of watches, by making common use for the power supply cells and avoiding that two electric components are driven at the same time.
CONSTITUTION: The power supply cell 6 is connected to the watch 1 and the alarm circuit 5, and the coil 2, gist switch 3, and gate circuit 4 are provided between the watch 1 and the alarm circuit 5. Thus, normally, the power supply cell 6 supplies power only for the watch 1, and when the gist switch 3 is turned on at alarm set time, the operation of the watch 1 has priority via the gate 4, and no alarm circuit 5 is operative at the drive of the coil 2. Only when the coil 2 is not operative, the alarm circuit 5 is operated. Since the drive of the coil 2 is made in very short time, the alarm tone is practically made without intermission. Further, since the power supply for the watch 1 and the alarm circuit 5 is made common without giving any hindrance to the functions, the space for the cell 6 is made small to achieve desired objective.
