A timepiece includes a mechanical oscillator and an electromechanical transducer formed by an electromagnetic assembly including a coil and a magnet mounted on the balance of the mechanical oscillator. The induced voltage signal, produced by the electromagnetic transducer during each oscillation, exhibits, in a first half-alternation between the oscillator passes via the neutral position thereof, a first lobe of maximum amplitude having a first polarity and, in a second half-alternation following a passage via the neutral position, a second lobe of maximum amplitude having a second polarity opposite the first. An electric converter includes two power supply capacitors and a device for regulating the medium frequency of the mechanical oscillator. The first power supply capacitor is charged merely with a positive voltage whereas the second capacitor is charged merely with a negative voltage. A load pump is arranged to transfer electric loads between the two capacitors according to a time drift of the mechanical oscillator relative to a time base.
