Title:
TIMEPIECE COMPONENT AND METHOD FOR MANUFACTURING TIMEPIECE COMPONENT
Document Type and Number:
WIPO Patent Application WO/2016/093354
Kind Code:
A1
Abstract:
A timepiece component, provided with intermediate films (51a-51d) provided to at least part of the surfaces of parent materials (11a-11d) formed using a non-conductive first material as the primary component, and shock-absorbing films (21a-21d) layered over the intermediate films (51a-51d), the shock-absorbing films (21a-21d) being formed using a second material of greater tenacity than the first material. Configuring the timepiece component in this manner makes it possible to raise precision pertaining to manufacturing, reduce the weight of the timepiece, and impart high strength such that the timepiece does not readily break when an external impact occurs, even when the parent materials (11a-11d) are formed using a brittle material such as silicon.
