PURPOSE:To obtain an electronic time piece which is thin-shaped and excellent in its maintenance service property, by constituting all circuits required for a time piece by one semiconductor. CONSTITUTION:A display part 1, an electric power supply battery 3 and a circuit block 2 are contained between a time piece outside case 13 and a back 14. The circuit block 2 has all circuit elements required for a time piece function, and is constituted of a semiconductor. By constituting in this way, it is possible to obtain an electronic time piece which is thin-shaped and excellent in its maintenance service property. |
