OVERVIEW

New G-STEEL model that feature Carbon Core Guard structure. The case is made of fine resin that incorporates carbon fiber for light weight along with rigidity that is superior to that of resin alone.
In addition to features that prevent damage and deformation due to impact, G-STEEL Series models also boast compact* configurations. Even though these models have dynamic wide faces, they are also designed to provide a comfortable fit on the wrist. The light-on-dark LCD contributes to both functionality and face design.
All of this and more adds up to a powerful and tough-looking design.
