ABSTRACT:
In an analog electrical timepiece with a motor coil, when an external operating member is in a prescribed operating condition, the operating mode of the analog electrical timepiece is set to the data receive mode. Next, the analog timepiece generates a synchronization signal which is in synchronized to an external synchronization signal that is input from outside. Then, the analog electrical timepiece, when the operating mode is the data receive mode by the detection circuit, based on a synchronization signal and a data voltage signal that is a voltage signal induced around the motor coil by a data signal input from outside, generates and outputs a receive data.
