Abstract
A timepiece resonator including an inertia element suspended from a flexible strip deformable in a plane XY parallel to a longitudinal direction Y, and whose transverse extension along a transverse axis X, in projection onto the plane XY, is variable and of positive value on at least one side of the neutral axis (FN) of the strip, which includes, at a distance from its embedments, at least one rib extending substantially along an axis Z perpendicular to the plane XY, each having at least one generatrix which is farther from the neutral axis (FN) than the external surfaces of the sections of the strip located outside the ribs, and the longitudinal extension (LN) of each rib of the strip, along the longitudinal axis Y, is less than one fifth of the length L of the strip between its embedments.
