Interaction between two timepiece components

A timepiece mechanism comprising:

• at least a first component and a second component configured to cooperate with each other in a relative motion on a trajectory in an interface area,
• wherein a first path of the first component includes first actuation means configured to exert a contactless stress on second complementary actuation means comprised in a second path belonging to the second component,
• wherein, throughout a monotonous relative movement of the second path with respect to the first path, a change of interaction energy between the first component and the second component based on a change of a relative angle has a variable and a linear non-zero gradient, the gradient having at least one change point, the change point of the gradient corresponding to a transition angle, a level of the contactless stress being changed at the transition angle, and
• wherein the relative angle is formed by the first component and the second component when the second component pivots to the first component, the second component being configured to adjust a position at the transition angle independent of the contactless stress applied to the second component.
