A timepiece component having a front surface on which a pattern is formed and being incorporated in a timepiece, the pattern being visible from an outside of the timepiece, the timepiece component comprising:
- a base material in which a first groove, a second groove, and a flat portion are formed on the front surface as the pattern along a first direction, the base material being plate-shaped, wherein
- the flat portion is provided between the first groove and the second groove in a second direction orthogonal to the first direction,
- a first wide width portion and a first narrow width portion are alternately provided in the first groove in the first direction,
- a second wide width portion and a second narrow width portion are alternately provided in the second groove in the first direction,
- the first wide width portion and the second narrow width portion are alternately provided in the second direction,
- the first narrow width portion and the second wide width portion are alternately provided in the second direction,
- a width of the first wide width portion is wider than a width of the first narrow width portion, and a width of the second wide width portion is wider than a width of the second narrow width portion, and
- a depth of the first wide width portion is deeper than a depth of the first narrow width portion, and a depth of the second wide width portion is deeper than a depth of the second narrow width portion.
A timepiece component having a front surface on which a pattern is formed and being incorporated in a timepiece, the pattern being visible from an outside of the timepiece, the timepiece component comprising:
- a base material in which a first groove extending in a first direction is formed in the front surface as the pattern, the base material being plate-shaped, wherein
- in the first direction, a first wide width portion and a first narrow width portion are alternately provided in the first groove,
- a width of the first wide width portion is wider than a width of the first narrow width portion,
- a depth of the first wide width portion is deeper than a depth of the first narrow width portion,
- in a cross section as viewed in the first direction, a cross-sectional shape of the first wide width portion and a cross-sectional shape of the first narrow width portion are arcs having the same curvature.
