Abstract
PURPOSE: To make time corrections automatically by making second corrections by supplying a signal, picked up by a microphone contained with watertightness, to a second-directing reset-to-zero circuit by way of a filter, crest discrimination circuit and time signal discrimination circuit.
CONSTITUTION: The count content of counter 4 of watch circuit 1 is displayed by display unit 6 through display driver circuit 5. A time signal, picked up by microphone 7 contained with watertightness, is passed through active filter 9 and then supplied to crest discrimination circuit 10 for conversion into a binary signals before being led to time signal discrimination circuit 11. Then, discrimination circuit 11 discriminates a time pattern to send out a pulse besed upon it and 30-second directing reset-to-zero circuit 12 resets the second counter of counter 4 and also crrects display contents. Therefore, second correcting and start operations can be automatized to simplify correcting operations.
