Estimating the term…
A flexible guide for a rotary resonator mechanism, in particular of a horological movement, the guide including a first support, an element movable relative to the first support, a first pair of flexible strips connecting the first support to the movable element, so that the movable element can displace relative to the first support by bending the strips in a circular movement about a centre of rotation, the flexible guide being arranged substantially in a plane, including a prestressing device, the prestressing device being configured to apply a force for buckling the flexible strips by bringing the first support closer to the movable element, so that the flexible guide includes two stable positions of the element movable relative to the first support for which the return moment is zero, the two stable positions having a predetermined angle of rotation therebetween.
