A jumper for a timepiece movement is disclosed that includes a base and an elastically deformable arm extending from the base and provided with an abutment surface intended to cooperate with a notch of a mobile. The base may comprise a support element bearing the arm. The base may further comprise two link elements each linking an end of the support element to a fixed element of the base. The jumper may be associated with a control member arranged in such a way that an axial rotation of the control member provokes a displacement of the support element by deformation of a frame, of which the support element and the two link elements form sides. |
