A device for elastic guidance in rotation for a timepiece mechanism allows rotation of one element relative to another element about an axis of rotation Z defining an axial direction. The device includes construction blades that each includes an assembly fixing part having a body and a functional part extending from the body as far as one end. The assembly fixing part and the functional part are separated by at least one slot in at least two extensions which are elastically connected and extend in a radial direction transverse to the axial direction. The device also includes anchorage zones which are disposed at opposite axial ends of the flexible guidance device, and configured to be fixed to the elements.
