Problems solved by technology

[0006] However, in these methods, the constituent materials of the coating included in the final watch exterior part are an extremely small part of the materials used in manufacture, and the waste of materials is large, which is not preferable from the viewpoint of saving resources.
[0007] In addition, the collection of materials for film formation, the reuse of recovered materials, the use of resists, etc. increase the number of processes or use of chemical substances, which will lead to environmental burdens and increased costs.

Abstract

A watch external part is equipped with a substrate and a coating formed using a gas deposition method. The coating is selectively provided at a portion of a site observable in a state with the watch external part incorporated in a watch. The substrate is made of a material including one type or two or more types selected from a group consisting of sapphire glass, quartz, and plastic. The watch external part is further equipped with a ground layer having at least one layer between the substrate and the coating.

Description

technical field [0001] The present invention relates to a watch exterior member, a method for manufacturing the watch exterior member, and a timepiece. Background technique [0002] Timepieces are required to function as a practical product and to have excellent aesthetics (aesthetic appearance) as an ornament. [0003] Therefore, materials with excellent texture, such as various metal materials, are used for watch exterior parts (for example, refer to Patent Document 1). [0004] Furthermore, in order to further improve the appearance, a decorative layer (coating) is provided in a predetermined pattern. [0005] Conventionally, in order to form a decorative layer (coating film) in a predetermined pattern, vapor phase film formation such as vacuum deposition is performed in a state where a mask (resist, etc.) After film formation, unnecessary parts are removed by etching. [0006] However, these methods are not preferable from the viewpoint of saving resources because the...
