Regulating body for a wristwatch, comprising: a generator provided with a rotor and a stator with M+N coils, M being a whole number higher than, or equal to, 1; and an electronic regulating circuit having a first load impedance with an adjustable value for adjusting the current in N of said M+N coils, and therefore the rotational speed of the rotor. Only a limited number of coils is therefore used for the braking, the other coils continuing to supply the electronic regulating circuit.

Regulating body for a wristwatch

Movement for chronograph watch comprising: a barrel (); a main gear train (RH) for driving one or more current time indicators (); a regulator member comprising a generator () driven by the main gear train (RH), the generator powering an electronic regulation circuit () to control the speed of rotation of the main gear train as a function of a quartz oscillator (); a chronograph gear train (Rc) that can be brought into mesh with the main gear train (RH) to drive a timer indicator (). The chronograph gear train can be brought into mesh with a wheel () that performs more than one revolution per minute.
