Abstract
By configuring a timepiece component to include an intermediate film provided on at least a portion of a surface of a base material formed by using a nonconductive first material as a main component and to include a buffer film stacked on the intermediate film and mainly composed of a second material having a tenacity higher than that of the first material, the timepiece component may be manufactured with high precision, the weight thereof may be reduced, and even when the base material is formed by using a brittle material such as silicon, the timepiece component becomes resistant to breakage and capable of exhibiting high strength when an impact is externally applied.
Claims15
A timepiece component of a drive mechanism for driving hands of a mechanical timepiece, comprising:
- a base material consisting of silicon;
- an intermediate film comprising copper and provided on at least a portion of a surface of the base material;
- and
- a buffer film which is stacked on the intermediate film and is an electrodeposition resist made of an acrylic resin.
A method of manufacturing a timepiece component of a drive mechanism for driving hands of a mechanical timepiece, the method comprising:
- forming a base material consisting of silicon into a shape of the timepiece component of the drive mechanism of the mechanical timepiece by etching a substrate;
- forming an intermediate film comprising copper on at least a portion of a surface of the base material;
- and
- forming a buffer film by stacking, on the intermediate film, an electrodeposition resist made of an acrylic resin.
