Abstract
A mechanical timepiece oscillator includes, between a first element and a second inertial element, two distinct flexible strips returning the inertial element to a rest position in an oscillation plane, the projections of these strips crossing each other, in the rest position, at a point, through which passes the pivoting axis of the second solid inertial element, the embedding points of the strips in the first element and the second inertial element defining two directions in which each strip has a free length between its embedding points, and an axial distance between the pivoting axis and the farthest of its embedding points, and, for each strip, the embedding point ratio is comprised between 0 and 1, and the vertex angle at the crossing point of the directions of the strips is less than 70°.
