A radio controlled time piece 1 actively using a time-programmed receiving operation and a forced receiving operation with respect to a standard radio signal and having an object the enablement of highly accurate and efficient time correction by properly receiving time information or calendar information and the like by executing a minimum amount of receiving operations, having a receiving means 2, a timekeeping means 18, a display means 4, a control means 10 for controlling the drive condition of the timekeeping means 18, an external input means 7, and a control information storage means 8, wherein when performing singularly or consecutively a time-programmed receiving operation that operates when a prescribed timekeeping value of the timekeeping means is reached, based on a first receiving method and a forced reception operation which operates by the operation of the external input means 7, based on a second receiving operation method, the first receiving method of time-programmed receiving operation and the second receiving method of forced receiving operation being established so as to be mutually different.
A radio controlled time piece which receives a standard radio wave signal including a standard time information signal and performs time correction based on the standard time information signal, comprising a receiving means, a timekeeping means for keeping time or calendar information, a display means, a control means for controlling a drive condition of said timekeeping means, an external input means, and a control information storage means, wherein when performing singularly or consecutively a time-programmed receiving operation that operates when a prescribed timekeeping value of said timekeeping means is reached at a predetermined time keeping information, based on a first receiving method, and a forced reception operation which operates by operation of said external input means, based on a second receiving operation method, said first receiving method of time-programmed receiving operation and said second receiving method of forced receiving operation are established so as to be mutually different.
A time correction method in a radio controlled time piece configured so as to perform time correction based on receiving a standard radio wave including a standard time information signal, comprising a first receiving method step of performing time-programmed receiving operation based on a first receiving method and a second receiving method step of performing forced receiving operation based on a second receiving method, wherein, when singularly or consecutively performing said first receiving method step and said second receiving method step, said first receiving method step and second receiving method step mutually differ.
