ABSTRACT:
It is made possible to display a time instant and a reception sensitivity even during a standard radio signal is received, without adding a special constitution as much as possible. A reception circuit receives and outputs a time code included in the standard radio signal, through an antenna, and a control circuit corrects a time instant being clocked to a time instant corresponding to the time code. In a case where the reception sensitivity of the standard radio signal is displayed, the control circuit judges the reception sensitivity of the standard radio signal on the basis of the time code from the reception circuit, and controls such that, by rotation-controlling a date indicator by referring to a reception sensitivity versus date indicator position correspondence table, the reception sensitivity is displayed by date letters of the date indicator and a time instant display is performed by time instant hands.
