- G-Shock GST-S100G-1A

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes G-STEEL, a watch 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.
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.
