Assembly intended to equip a timepiece mechanism and comprising at least one elastic element and at least one first and one second timepiece components the elastic element comprising a first end intended to cooperate with the first component and a second end intended to cooperate with the second component and the elastic element exerting, in the operating position of the assembly, a stress on the first and second timepiece componentswhich tends to displace one of the said timepiece components with respect to the other, wherein the first component, the elastic element and the first end are shaped so that, in the operating position of the assembly, the torque exerted by the elastic element on the first component and the second component keeps the first end of the elastic element in abutment on the first component at at least three first point bearing zones arranged to eliminate at least two degrees of freedom of movement between the first end of the elastic element and the first component.
