PROBLEM TO BE SOLVED: To attain the life termination display of a battery without additional means, make easy to manufacture, and enable the display to be reset to the normal display mode when the charge characteristic is resumed even in the case when the display of life termination is made at a time. SOLUTION: This timepiece is provided with a battery 10, a motor 11 driving indicators 13, 14, 15, a motor 12 driving a day display pannel 16 and a microprocessor 22 adapted for timepieces. When an electric circuit 23 measures service life of the battery 10, the microprocessor 22 drives the motor 12 for shifting the pannel 16 from the normal position, and then the life termination display of a battery marked with a supplementary display symbol is made on the window 17 of the timepiece, e.g. on the day part. |
