Abstract: PROBLEM TO BE SOLVED: To provide an pointer-type electronic timepiece including a radio communication means, and a communication system constituted of the electronic timepiece and an electronic device such as a cellular phone, wherein stable data communication is performed without hindering operation of the electronic timepiece.
SOLUTION: A communication timing control means is provided in the electronic timepiece, and a communication interval by the radio communication means and an operation period are set to have the same period, and control is performed so that communication timings (e2-t2) by the radio communication means are not overlapped on driving timings (e1-l1, s1-u1) of a pointer. When performing a heavy-load processing such as quick forwarding operation (m1-q1), the communication interval is changed by transmitting communication interval changing information to the cellular phone.
