Abstract
A watch () including an electromechanical movement provided with a stepper motor () and a control circuit () of the motor, and configured to communicate with an external communication device (), including an antenna formed by the coil () of the motor and arranged to receive an amplitude-modulated magnetic signal according to the encoded data. The communication involves the generation of electrical detection pulses supplied to the coil of the motor with a pulse frequency corresponding to an encoding frequency of the magnetic signal.
