Abstract: An electronic timepiece includes: a first time counter which clocks the time; a first timer which clocks a predetermined elapsed time period from the time of communication establishing processing with a portable electronic device; and a near field wireless communication portion which is capable of establishing communication in a case of synchronizing the time with the time of the portable electronic device. The portable electronic device includes a second time counter which clocks the time, a second timer which clocks the predetermined elapsed time period from the time of communication establishing processing with the electronic timepiece, and a near field wireless communication portion which is capable of establishing the communication in a case of synchronizing the time with the time of the timepiece, and sends time data which synchronizes the time of the first time counter with the time of the second time counter to a first communication portion in a case where the predetermined time period has elapsed in the second timer.
