Features From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes G-STEEL, a watch series with a new "layer guard structure".Different materials are used for the bezel to create a two-layer structure that adds a new dimension of shock resistant. For models that use stainless steel in the upper part, shock absorbing resin is employed in the lower part. If resin is used in the upper part, fine resin is used in the lower part to cushion against impact from the upper part. This also has made it possible create a wide range of different designs.The GST-S100 model features a tough, quality design molded of resin.A hand shift feature temporarily moves hands out of the way with the press of a button for easy reading of digital display contents, while double LED face illumination keeps information easy to read at all times.• Layer guard structure• Tough Solar• Hand shift feature• Double LED light illuminates the face and digital display for outstanding readability.
