    • PURPOSE: An electronic watch is provided to have a function of storing the electric energy generated for use in driving the same. CONSTITUTION: An electronic clock provided with a generating means (10) which generates power with external power supply, a storing means (30) which stores electric power generated by the generating means (10), and a timing mechanism which displays the time with the electric power generated by the power generating means (10) or electric power stored in the storing means (30). In the electronic clock, an operating means (80) which calculates the ratio between the generated voltage by the generating means (10) and the stored voltage by the storing means (30), a switching means (40) which switches the connection and disconnection among the generating means (10), the storing means (30), and the timing means (20), and a controller (50) are installed. The controller (50) controls the closing and opening of the switching means (40) according to the ratio calculated by the operating means (80).
