Document Type and Number:
WIPO Patent Application WO/2014/090830
Kind Code:

Abstract:
The invention relates to a regulating body for a wristwatch, comprising: a generator provided with a rotor (12) and a stator with M+N coils (10, 10'), M being a whole number higher than, or equal to, 1; and an electronic regulating circuit (2) having a first load impedance (Z1) with an adjustable value for adjusting the current in N of said M+N coils (10'), 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.
