We have developed a new power supply system for solar battery watches. The features are as follows : 1. Charging system is unnecessary, -No need for storage battery or back-up condenser, 2. Dual power supply, -Furnished with both solar battery and lithium battery, Lithium battery serves as back-up power source whenever illumination is such that solar battery alone is not sufficient, 3. Simple construction and high reliability.
