Problems solved by technology

[0004] However, in the timepiece part described in Patent Document 1, a certain thickness is required in order to constitute the stress relaxation layer with a metal film, and accordingly, the weight of the timepiece part also increases.
Therefore, even if the base material is made of silicon, the effect of reducing the inertial force of the watch parts is reduced.

Abstract

The invention provides a timepiece component, which can inhibit chipping of a silicon-made substrate and which can inhibit a weight increase. An escape wheel (an example of a timepiece component) hasa silicon-made substrate having an insertion portion into which an axle is inserted, and a coating film formed in a contact portion which comes into contact with at least the axle, on a front surfaceof the substrate. The coating film contains metal alkoxide having a fluorine atom.

Description

technical field [0001] The present invention relates to a watch component, a watch movement, and a watch. Background technique [0002] Mechanical timepieces are equipped with a large number of timepiece components represented by gears and the like. A timepiece component such as a gear is formed by inserting a shaft into a through hole (holding portion) provided at the center of a rotating component formed with a plurality of teeth on the outer periphery and fixing (holding). While timepiece components have conventionally been formed by machining metal materials, in recent years substrates containing silicon have been used as materials for timepiece components. Since timepiece components based on silicon are lighter than metal-based components, the inertial force of the timepiece components can be reduced, which is expected to improve energy transmission efficiency. In addition, silicon has an advantage that since the degree of freedom of shape formed by photolithography o...
