A radio correcting timepiece that can reduce the influence of a radio wave situation of the standard radio wave having time information according to an area, and can make a correction to the exact time in a shorter time is provided. The radio correcting timepiece comprises a signal receiving means () for receiving a standard radio wave and a timepiece means () for correcting and displaying time on the basis of the time information outputted from the signal receiving means. The signal receiving means () can receive plural standard radio waves and includes memory means (I) which is able to store signal receiving order of the plural standard radio waves. Since the plural standard radio waves can be received, the influence of a radio wave situation according to an area can be reduced and a correction to the exact time can be made in a shorter time by using the standard radio wave transmitted every minute.
