<P>PROBLEM TO BE SOLVED: To provide an analog radio correction watch that inspects the disagreement between the time of an internal clock and time indicated by electronic clock hands for correction when possible, and warms a user that time display is not based on standard time even if standard time radio waves are successfully received when it cannot be corrected. <P>SOLUTION: The analog radio correction watch comprises the internal watch A-2 for generating internal time; electronic clock hands B for displaying display time while being driven by the internal watch; a reception circuit G for receiving standard time radio waves; a means L for displaying the result of the reception success of the standard time radio waves in the reception circuit; a control unit A-1 that is a means for correcting the internal time of the internal watch and the display time of the electronic clock hands, based on the standard time when the reception circuit succeeds in reception; a means D for detecting agreement/disagreement between the internal time of the internal watch and the display time of the electronic clock hands; and the control unit A-1 that is a means for setting the display of a means for displaying the result of the reception success as the display of reception failure, when disagreement is detected by a detection means. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
