AI Technical Summary

Technical Problem

Existing decorating methods for timepiece dials, such as those described in JP 2022-11407 A, fail to provide a sufficient stereoscopic effect for hour indicators while maintaining a thin profile, and embedding abbreviated characters complicates the design.

Method used

A decorating method using laser processing to create a recessed portion with intersecting grooves and protruding portions on the dial, forming a stereoscopic hour indicator by digging down the decorative portion from the front surface, allowing for high contrast and reduced thickness.

Benefits of technology

The method achieves a clear, stereoscopic hour indicator with high contrast and reduced thickness, enabling a thinner timepiece design without the need for embedded characters, and allows for adjustable lightness and design variations through groove depth control.
