FIELD: watches and other time measuring instruments.
SUBSTANCE: clock escapement (100) with improved tribology, which includes first component (2) and second component (3), respectively, including first friction surface (20) and second friction surface (30), designed to interact in contact with each other, wherein second friction surface (30) includes at least one silicon-based material, selected from the group including silicon (Si), silicon dioxide (SiO2), amorphous silicon (a-Si), polycrystalline silicon (p-Si), porous silicon or a mixture of silicon and silicon oxide, and wherein first friction surface (20) is formed by the surface of a solid element, which is made of solid silicon nitride in the stoichiometric composition of Si3N4.
EFFECT: lubricant-free clock escapement is provided.
