To make a setting as to whether or not a time code is automatically received simple, and suppress a wasteful use of an electric power by a reception operation under an environment incapable of suitably receiving the time code. A reception circuit receives and outputs the time code through an antenna, and a control circuit corrects a time instant which is being clocked to a time instant corresponding to the time code. If a crown is operated to a time instant correction position, an input circuit outputs an operation signal denoting this. The control circuit responds to the operation signal to thereby control a reception operation of the reception circuit to OFF. At this time, a time instant correction is performed by hand by operating the crown. |
