摘要： A watch component of the present disclosure includes a substrate, and a multilayer film covering at least a part of the substrate. A plurality of recesses is formed in a surface, of the substrate, facing the multilayer film. In a cross-sectional view obtained by cutting the substrate in a thickness direction, the plurality of 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, a ratio of a length of the second side along the thickness direction of the substrate with respect to a length of the second side along a direction orthogonal to the thickness direction of the substrate is greater than ½. The multilayer film includes three or more layers of a color absorption film composed of a material including Cr. A value of a brightness L* in a L*a*b* color space is equal to or less than 10 in plan view as viewed from the thickness direction of the substrate.

摘要： A watch component includes 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. 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. 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.
