A radio wave-corrected timepiece permitting one to easily judge whether radio waves containing correct information about time or radio waves containing abnormal information about time are being received. A radio wave-corrected timepiece comprising receiving means 101 for receiving radio waves containing encoded information about time and producing a rectangular pulse train containing encoded information about time, memory means 102 for storing the rules of the encoded information about time, comparing means 103 for comparing the output signal from the receiving means 101 with the output from the memory means 102, and calculating means 104 for receiving the output from the comparing means 103, calculating the time, and providing an output permitting correction of the contents of a timing signal generating means 132. <IMAGE> |
