A timepiece assembly including a combined resonator with at least two degrees of freedom which includes a first linear or rotary oscillator with reduced amplitude in a first direction relative to which oscillates a second linear or rotary oscillator with reduced amplitude in a second direction substantially orthogonal to the first direction. The rotary oscillator includes a second weight carrying a sliding-block. A wheel set is arranged for application of a torque to the resonator, the wheel set including a groove in which the sliding-block slides with minimal play. The sliding-block is arranged at least either to follow curvature of the groove when present, or to rub with friction in the groove, or to repel the inner lateral surfaces of the groove by magnetically or electrically charged surfaces in the sliding-block.

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.

A horological resonator mechanism (100) including a structure (1) and an anchor unit (30) from which is suspended at least one inertial element (2) arranged to oscillate, with a first degree of rotational freedom RZ, about a pivot axis (D) extending in a first direction Z. The inertial element (2) is subjected to return forces exerted by a flexible guide (200) forming a virtual pivot, the anchor unit (30) being suspended from said structure (1) by a flexible suspension (300) arranged to allow said anchor unit (30) to move with a plurality of degrees of freedom. A retaining device (10) provides the flexible suspension (300), which is configured to damp the rotation of the inertial element (2) and of the flexible suspension (300) about the second direction X, and/or about the third direction Y.
