A timepiece regulator comprising an inertial regulating member which is mounted on a support by an elastic suspension so as to be able to oscillate in translation, along a main direction of translation.

A monolithic timepiece regulator made in a single plate, comprising an external rigid element, an internal rigid element, and elastic suspensions connecting the external rigid element to the internal rigid element and enabling oscillatory rotating movements between them. The internal rigid element has arms which are rigidly connected with one another, leaving between each other free angular spaces, and the elastic suspensions are located in these free angular spaces.

The oscillator for a regulator of a timepiece mechanism comprises a frame, a rigid body and a mechanism) for connecting the rigid body to the frame enabling oscillations of the rigid body relative to the frame. The connecting mechanism comprises at least one first and one second rigid parts, and a first and a second flexible elements, in the form of angular sectors of rings. The first and second flexible elements extend mainly in separate non-parallel planes. The first and second flexible elements are concentric. The first and second flexible elements each connect the first and second rigid parts together.
