DETAILED DESCRIPTION - A horological regulator mechanism comprises resonator mechanism comprising a virtual pivot on main axis and flexure bearing arranged on a plate (1) and having quality factor (Q) of more than 1000, and an escapement mechanism which is subjected to a torque from drive unit in a movement. The resonator mechanism comprises an inertial element (2) arranged to oscillate relative to the plate. The inertial element is subjected to the effect of elastic return unit arranged directly or indirectly attached to plate, and is arranged to indirectly cooperate with an escape wheel set (4) in the escapement mechanism. The escapement mechanism is free. The resonator mechanism has at least one phase of freedom which is not in contact with the escapement mechanism, during the operating cycle. The regulator mechanism comprises at least one pair of components comprising component (C1) and component (C2) containing rubbing surface (S1) and rubbing surface (S2) arranged to cooperate and in contact with one another. The component (C1) comprises silicon carbide which is either stoichiometric silicon carbide or non-stoichiometric silicon carbide, silicon carbide-hydrogen of formula: SixCyHz (I), where x is 1, y is 0.8-5.0 and z is 0.00-0.70, or material comprising at least 90 wt.% silicon carbide and at least one other material chosen from alpha-6H silicon carbide, beta-3C-silicon carbide, 4H-silicon carbide, fluorinated silicon carbide, silicon carbonitride, 400-2000 ppm aluminum, less than 3000 ppm iron, 0.04-0.14 wt.% boron, boron carbide, polyphenylic boron, decaborane and/or carborane (in total), less than 8000 ppm carbon, vanadium carbide, zirconium carbide, yttrium-doped alpha-silicon oxynitride, graphene and less than 500 ppm impurities at rubbing surface (S1). The component (C2) comprises at least one silicon-based material chosen from less than 400 ppm silicon, deoxidized silicon, less than 8000 ppm silicon dioxide, amorphous silicon, polycrystalline silicon, porous silicon or a mixture of silicon and silicon oxide, stoichiometric silicon nitride, non-stoichiometric silicon nitride (I) and oxynitrides of formula: SixOyNz (II) at rubbing surface (S2). The rubbing surface (S2) is the surface of a component comprising at least one silicon-based material. The rubbing surface (S1) is the surface of a component (C1). INDEPENDENT CLAIMS are included for the following: (1) horological movement; and (2) production of the regulator mechanism.
