An electronic device in which physical energy is transferred between a station and an electronic timepiece to carry out power transmission and data transmission. In the station, a packet generator generates either charge packets or data packets. The station sends the generated packets to the electronic timepiece by means of an electromagnetic coupling with the electronic timepiece. In the electronic timepiece, a packet comparator determines the type of the packets sent from the station. Depending on the determination by the packet comparator, the electronic timepiece switches operations between the charging of the rechargeable battery with physical energy and the writing of data to memory.
