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.
2 . 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 multilayer film at which the first transparent film is partially formed, 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.
3 . The watch component according to claim 1 , wherein
a freely selected pattern is formed at a surface, of the substrate, covered with the multilayer film.
4 . The watch component according to claim 1 , wherein
the freely selected pattern of the first transparent film is formed by an inkjet printer.
5 . The watch component according to claim 1 , wherein
an absolute value of a difference in refractive index between the first transparent film and the second transparent film is 0.06 or greater.
6 . A watch configured using the watch component according to claim 1 , wherein
any one of a dial, an oscillating weight, an abbreviation, a hand, a bezel, or a belt is configured using the watch component.
7 . 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.
8 . The method for manufacturing a watch component according to claim 7 , further comprising
a substrate pattern forming step of forming a freely selected pattern at a surface, of the substrate, to be covered with the multilayer film, substrate pattern forming step being performed before the multilayer film forming step.
9 . The method for manufacturing a watch component according to claim 7 , wherein
in the first transparent film forming step, the first transparent film is formed in a freely selected pattern by an inkjet printer.
10 . 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 multilayer film at which the first transparent film is partially formed, 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.
