ABSTRACT:
To make such that, in a case displaying the fact that a time code could not be normally received in an analog radio-controlled timepiece, by a simple constitution there is performed a display having no sense of discomfort for a user. In a case where there could not be normally received in a time code reception operation in the last time, a second hand is normally moved by 1 second. In a case where there failed in a reception, after the second hand was normally moved till a 55-second position, the second hand is stopped at the 55-second position till a second time instant becomes 59 seconds. When it became 59 seconds, by fast-forwarding the second hand till an exact second position, the fact that the time code could not be normally received is displayed by the display having no sense of discomfort for the user without using an exclusive display means, and the like.
