Timepiece wheel set with a unidirectional wheel including an arbor carrying a pinion and at least a first wheel that is coaxial with this pinion and pivotally mounted on this arbor, this first wheel being connected to the arbor by elastic rotational return means or at least a first spring constituting first means of uncoupling, which exert a friction force on this first wheel, and the wheel set including a second wheel pivotally mounted on this arbor, and connected to this arbor by second elastic rotational return means or at least a second spring constituting second uncoupling means, which exert a friction force on this second wheel. |
