<p>PROBLEM TO BE SOLVED: To improve the degree of freedom and the speed of regulation and to easily transmit a large quantity of data by regulating a regulated part based on regulation data received synchronizing with a synchronous signal from the outside through a driving motor unit. SOLUTION: In an external regulation device 30, a receiving unit 32 detects the magnetic field of the motor coil of an electronic timepiece, performs rate measurement based o received output, next produces a regulated mode signal synchronized with the receiver motor driving signal and outputs. In the electronic timepiece, when a received regulation mode signal is synchronized with an inner synchronous signal, a motor drive signal is not output. In the external regulation device 30, a confirming signal generated when the receiving unit of the electronic timepiece receives the external synchronous signal three times is received, a correction data signal is produced, and it is transmitted to the electronic timepiece. In the electronic timepiece, when the receiving unit receives a data signal at timing of inner synchronous signal pulse synchronized with the external synchronous signal, correction data is produced from the signal level.</p> |
