Abstract
A watch component of the present disclosure includes a substrate, a multilayer film that covers at least a part of the substrate and includes a color adjusting film having a function of adjusting a color tone, a first transparent film stacked at the multilayer film, having a predetermined refractive index, and formed in a freely selected pattern, and a second transparent film stacked at the first transparent film or the multilayer film, and having a refractive index different from that of the first transparent film by a predetermined difference.
Claims10
A watch component comprising a region, the region including:
- a substrate,
- a multilayer film covering at least a part of the substrate and including a color adjusting film having a function of adjusting a color tone,
- a first transparent film stacked at the multilayer film, having a predetermined refractive index, and formed in a freely selected pattern, and
- a second transparent film stacked at the first transparent film or the multilayer film, and having a refractive index different from that of the first transparent film by a predetermined difference,
- wherein a color difference between a portion where the first transparent film is formed and a portion where the first transparent film is not formed is 1.6 or greater in plan view viewed from a thickness direction of the substrate as determined by measuring an average reflection light at an incident angle of 0 in a CIE 19644 space with a CIE standard light source.

A method for manufacturing a watch component, the method comprising:
- a multilayer film forming step of forming a multilayer film to cover at least a part of a substrate, the multilayer film including a color adjusting film having a function of adjusting a color tone;
- a first transparent film forming step of stacking, at the multilayer film, a first transparent film having a predetermined refractive index and formed in a freely selected pattern, the first transparent film forming step being performed after the multilayer film forming step;
- and
- a second transparent film stacking step of stacking, at the first transparent film or the multilayer film, a second transparent film having a refractive index different from that of the first transparent film by a predetermined difference, the second transparent film stacking step being performed after the first transparent film forming step,
- wherein a color difference between a portion where the first transparent film is formed and a portion where the first transparent film is not formed is 1.6 or greater in plan view viewed from a thickness direction of the substrate as determined by measuring an average reflection light at an incident angle of 0 in a CIE 19644 space with a CIE standard light source.
