Abstract:
An electronic timepiece comprising:a timepiece driving circuit for performing a time-keeping operation; a display circuit for displaying time information from said timepiece driving circuit, wherein; a generator for generating electric energy utilizing at least one type of external energy; and a capacitor device for storing said electric energy generated by said generator and supplying said stored electric energy to said timepiece driving circuit, said capacitor device comprising an equivalent capacitive component for storing an electric charge and a resistive component formed by a part of said equivalent capacitive component, said resistive component having a resistance causing a voltage drop due to a charging current from said generator when said generator outputs a current equal to or greater than a predetermined value, said voltage drop making a voltage applied to said timepiece driving circuit equal to or greater than an operation starting voltage by which said timepiece driving circuit starts operating; wherein said timepiece driving circuit is coupled in parallel to said capacitor device, and said timepiece driving circuit and said capacitor device are jointly coupled across said generator.
