Abstract
A mechanical oscillator with an inertia element oscillating about a virtual pivot axis of fixed position with respect to a fixed base to which it is suspended by several flexible connections, each including a deformable compass-like member including elastic strips forming a first arm fixed to a base and a second arm fixed to the inertia element, joined at a reversal edge defining a apex of the deformable compass-like member, wherein in an unstressed rest state of the oscillator, the projection of the apex is on a first side of the pivot axis, opposite to a second side where the ends of the first and second arms are projected.
