PURPOSE:To simplify and speedup the manufacturing process of a dial while designing the dial with superior movelty, by irradiating the surface of a timepiece display member with laser light. CONSTITUTION:A thin plate material is lapped and pressed into the outward shape of a plate 11. The plate 11 is fixed on a flat plate and the laser light is scanned perpendicularly to sublime and remove the material of the plate 11 at the center part of the laser light irradiation, forming a rugged part. The output is increased for large contrast irradiation traces (patterned) and decreased for small contrast irradiation traces (patterned), thus realizing a striped pattern 13. |
