PROBLEM TO BE SOLVED: To provide a timepiece wheel set, with one or a plurality of inputs and capable of providing a different response depending on a pivoting direction imposed thereon by one or another of inputs.SOLUTION: A timepiece wheel set 8 is provided which has a unidirectional wheel including an arbor 80 carrying a pinion 81 and at least one first wheel 82 coaxial with the pinion 81 and pivotally mounted on the arbor 80. The first wheel 82 is connected to the arbor 80 by first elastic rotational return means or at least one first spring 84 constituting first means of uncoupling 91, which exerts a friction force on the first wheel 82. The wheel set 8 has a second wheel 86 pivotally mounted on the arbor 80. The second wheel 86 is connected to the arbor 80 by a second elastic rotational return means or at least one second spring 88 constituting a second means of uncoupling 92, which exerts a friction force on the second wheel 86. |
