Abstract
The timepiece comprises a detector and control circuit for the stepping motor. This circuit comprises on the one hand an amplifier including at least a MOS transistor receiving on a first terminal a voltage representative of the current in the driving coil of the motor and having a second terminal joined up to a condenser connected to one of the poles of a power source. The amplifier delivers signals representative of the current in the condenser. The circuit comprises on the other hand means connected to the amplifier for controlling the driving pulses. The circuit is easy to integrate and it has a very low power consumption.
