PROBLEM TO BE SOLVED: To provide a radio-controlled watch capable of receiving standard wave of a plurality of stations, having a simple constitution. SOLUTION: By turning on and off a frequency selection switch, turning over the parallel connection number of tuning capacity and varying capacitance value, the tuning frequency is controlled. By making the electric potential at one end of antenna to be the same as the electric potential at on-time of the frequency selection switch on the other hand, the frequency of a local circuit is selected as an electric potential at the on-time of the frequency selection switch from the control terminal of an electronic frequency selection means. |
