Abstract (en)
[origin: US2021055695A1] A horological regulator mechanism including a resonator mechanism having a virtual pivot and flexure bearing, with a quality factor greater than 1,000, the inertial element whereof indirectly cooperates with a free escapement mechanism, during the operating cycle whereof the resonator mechanism has at least one phase of freedom wherein it is not in contact with the escapement mechanism, this regulator mechanism comprises a pair of components including rubbing surfaces arranged to cooperate and be in contact with one another, whereby the first rubbing surface is formed by the surface of an element comprising silicon carbide.
