The timepiece includes means for adjusting the shake of a rotating part or wheel set, in particular a balance one bearing of which is arranged in a bar (4). This bar comprises a base (18) associated with a adjusting screw (34) one end (36) of which rests on the bottom plate. Rotating this adjusting screw varies the distance between the base and the bottom plate (14). The center of the adjusting screw is pierced for the passage of a tightening screw (32) for fixing the bar to the bottom plate. This adjusting screw is arranged in a hole (42) passing through the base (18) and can be rotated through the hole from the top face (46) of the bar in order to adjust the balance shake.
