Abstract
PURPOSE: To prevent the power voltage reduction to the heavy load only at the low temperature time by inserting the switch or the temperature-sensitive resistance element between the cell and the capacitor.
CONSTITUTION: Switch 7 is inserted between cell 5 and capacitor 6 and opened at the normal temperature. When switch 7 is closed at the low temperature, capacitor 6 is charged at the light load driving time in the electronic circuit 2 and the like of the watch. And the power voltage reduction according to the reduction of the inner resistance caused by the low temperature can be prevented for cell 5 owing to the discharge energy of capacitor 6 at the driving time of the heavy load of driving circuit 3 and the like. As a result, the consumption of the leak current is limited only at the low temperature, thus avoiding the undesired power consumption and accordingly ensuring good driving for the light and heavy load of the watch. The temperature-sensitive resistance element can also be used in place of the switch to obtain the same effect.
