PROBLEM TO BE SOLVED: To obtain the structure of optical power generation type electronic timepiece which can greatly extend battery life. SOLUTION: This timepiece is provided with a detection circuit mechanism 110 for detection the state of power generation of an optical power generation element 101 and a storage circuit mechanism 109 for storing the detected result. Then, when it is detected that the quantity of power generation in the element 101 is less than a given value, a dark state is stored in the storage circuit 109 and the movement of second pointer is stopped, and, on the other hand, when it is detected that the quantity of power generation in the element 101 is more than the given value, a bright state is stored in the storage circuit 109 and the second pointer is moved again. |
