A timepiece resonator comprises mechanically connected first and second oscillating crystals connected respectively in the collector-emitter and collector-base circuits of a transistor. At least the first crystal is secured to a blade adjacent to a clamping point of the blade, and a free end of the blade, carrying driving means for cooperation with a pinion, oscillates at a sub-harmonic of the resonant frequency of the crystals.
