Palladium, pink gold and DLC plating are used in the watch industry, and are applied to watch cases and parts. Palladium is valued as a decorative metal, as well as for its wear and corrosion resistance and its durability. Pink gold is used for its appearance and its wear resistance.
Using PVD Sputtering Technology, it has Good Hardness and Scratch Resistant. Can be Used for Decorative Purposes, Tools, Jewelry and etc.

The world's first off-body protector structure Developed in 1975 as the World's First Body Protector. It was developed for its highly Reliable Shock Resistive and Safety feature on Diver's Watch. In 1986, ceramics material was used for the Quartz Models of 100M Diver Watch and characteristics of being light weight, high corrosion-resistant and high hardness.
Plating technique using a constant voltage on the case to avoid the double layer and coating roughness.
