Jewelry has the origin of precious metal dog head lettering.

When Switzerland revised the Regulations on Precious Metal Labeling in 1995, it was stipulated that the profile head of Saint Bernard, the national dog, was the only Swiss-made precious metal product logo, and the material was expressed in the shape of an internationally unified balance logo, and the color was expressed in numbers and words. Below are the logo shapes and corresponding material patterns. Since then, there are four kinds of marks on the modern Swiss gold watch case: Saint Bernard dog, material balance mark, color mark and manufacturer's responsibility mark or trademark.
