PURPOSE:To correct the time of the watch more accurately by the use of the time announcement of radio broadcasting by correcting the time required for time announcement detection. CONSTITUTION:This is provided with electronic watch circuits 26-30 which permit setting at the specific time faster slightly from at least the just time, a receiving circuit A for broadcasting radio waves and a circuit 31 which corrects the time of the electronic watch circuits at the specific time depending upon the time. By setting these circuits at the time faster by the difference between the time to be subjected to time correction by the time announcement and the just time, the time required for a time announcement detecting circuit 21 to detect the time announcement is corrected. |
