Watch component, watch, and method for manufacturing watch component

A watch component comprising:

• a substrate including a first region where a plurality of first recesses is formed in a surface, and a second region where a plurality of second recesses is formed in the surface;
• and
• a multilayer film covering at least a part of the first region and the second region, wherein
• in a cross-sectional view obtained by cutting the substrate in a thickness direction, the plurality of first recesses is defined by a first side, and a second side tilted with respect to the first side and being in contact with the first side at an end portion,
• in the cross-sectional view, the plurality of second recesses is defined by a third side, and a fourth side tilted with respect to the third side and being in contact with the third side at an end portion,
• in the cross-sectional view, an angle of an inclination of the second side with respect to a direction orthogonal to the thickness direction of the substrate and an angle of an inclination of the fourth side with respect to the direction orthogonal to the thickness direction of the substrate are different from each other, and
• the multilayer film includes three or more layers of a color absorption film composed of a material including Cr.

A method for manufacturing a watch component, the watch component including:

• a substrate including a first region where a plurality of first recesses is formed in a surface, and a second region where a plurality of second recesses is formed in the surface and
• a multilayer film covering at least a part of the first region and the second region, the method comprising:
• forming the plurality of first recesses and the plurality of second recesses in a surface of the substrate;
• and
• stacking the multilayer film in at least a part of the first region of the substrate where the plurality of first recesses is formed and the second region of the substrate where the plurality of second recesses is formed, wherein
• in a cross-sectional view obtained by cutting the substrate in a thickness direction, the plurality of first recesses is defined by a first side, and a second side tilted with respect to the first side and being in contact with the first side at an end portion,
• in the cross-sectional view, the plurality of second recesses is defined by a third side, and a fourth side tilted with respect to the third side and being in contact with the third side at an end portion,
• in the cross-sectional view, an angle of an inclination of the second side with respect to a direction orthogonal to the thickness direction of the substrate and an angle of an inclination of the fourth side with respect to the direction orthogonal to the thickness direction of the substrate are different from each other, and
• in plan view as viewed from the thickness direction of the substrate, the first region and the second region have a value of a brightness L* in a L*a*b* color space of 5 or greater and 20 or less.
