Abstract: A tuner with a timepiece for a watch radio includes a display on which either a current time being counted by the timepiece or a frequency being received by the tuner is selectively displayed, and a first key group including a plurality of keys which are operated to control a function of the timepiece and a second key group including a plurality of keys which are operated to control a function of the tuner. An operation of the second key group is inhibited when the current time is displayed on the display. In this state, a displaying state of the display is automatically changed and the frequency is displayed on the display if a band key included in the second key group is operated, and thereafter the operation of the second key group is allowed to control the function of the tuner.
