Beschreibung
Zusammenfassung:	A timepiece with, in order to regulate the speed of rotation of a rotating wheel set, a regulating device including a microgenerator and an LED powered by the microgenerator without storage of electrical energy and arranged such that, for a range of functional speeds of the rotating wheel set, the corresponding range of frequencies of rotation of the rotor of the microgenerator generates, in its coils, an induced voltage range whose maximum voltage value for the maximum frequency is greater than a threshold voltage, preferably also the minimum voltage value for the minimum frequency, the motor device which drives the rotating wheel set being arranged to have a useful motor torque range allowing the rotating wheel set to be driven within the functional speed range. Also a related method.
