Abstract
A data transmission/reception system for wrist-type electronic timepiece. The data transmission/reception system for electronic timepieces comprises a data transmission device for generating data signals, and an electronic timepiece that receives data signals from the data transmission device by utilizing a coil for driving the hands, wherein the electronic timepiece is provided with a timing signal-generating means which generates a timing signal, and the data transmission device is provided with a timing signal-receiving means which receives the timing signals output from said hand-driving coil and transmits data signals in synchronism with the timing signals that are received. The data are transmitted and received in an ordinary hand-moving state without halting the timepiece while the functions are being operated. Therefore, there is no need of adjusting the time after the operation of the functions.
