PURPOSE:To shorten an inspection time necessary for time matching to a large extent by providing a test mode indicating means, a time setting mode indicating means and a prescribed time setting means. CONSTITUTION:A test mode indicating part 17 consisting of a pull-up resistor 14 and a changeover switch 15 changes over the time setting function of a built-in timepiece to either one of a usual mode and a test mode. When the switch 15 is in an OFF-state, the input terminal M of a control circuit part 16 becomes an H-level by the resistor 14 and, when the switch 15 is in an ON- state, the terminal M is connected to the earth to become an L-level. When the switch 15 of the test mode indicating part 17 is turned ON to set the input terminal M of a microcomputer to an L-level and the circuit part 16 is set to a test mode, the circuit part 16 performs time setting in the test mode to instantaneously set the built-in timepiece to predetermined prescribed time. When the switch 15 is turned OFF to set the terminal M to an H-level, the circuit part 16 is set to a usual mode and usual time setting can be performed in the order of hr and min by the indication of the circuit part 16. |
