The present invention relates to a clock adjuster mechanism 300 comprising a resonator mechanism 100 having a virtual pivot and bending bearing and having a quality factor greater than 1,000, wherein the inertial element 2 of the resonator mechanism is a free escapement mechanism ( 200) and indirectly cooperating with each other, and during its operation cycle, the resonator mechanism 100 has at least one free phase that does not contact the escapement mechanism 200, and the regulator mechanism 300 cooperates with each other and It comprises a pair of components (22; 32) comprising a friction surface (20; 30) arranged to be in contact, whereby the first friction surface (20) is formed by the surface of an element comprising silicon carbide.
