Document Type and Number:
WIPO Patent Application WO/2021/044933
Kind Code:
A1
Abstract:
[Problem] To provide a facing ring in which it is possible to improve decorative properties while ensuring visibility, a method for manufacturing the facing ring, and a wristwatch provided with the facing ring. [Solution] Sapphire crystal, ruby crystal, diamond crystal, or glass is prepared as a member, and the planar shape of the member is formed as a square, a rectangle, a circle, an elliptical shape, or any polygon having three or more vertices. In addition, a cross-section of the member is formed at least from two orthogonal surfaces and one surface that is formed at an incline relative to the aforementioned two surfaces. Furthermore, a recess is formed in the one surface, a light-emitting material is positioned in the recess, and reflective materials are formed in at least one of the two surfaces to manufacture a facing ring. The light-emitting material of the facing ring is caused to emit light while irradiated with light or in the dark, and the light emitted from the light-emitting material is reflected by the reflective materials to project a virtual image within the member. Furthermore, the facing ring is provided to the face of a wristwatch, and a reflective material is formed at least in a surface that is in contact with the face, from among the two surfaces.
