About GST-W100 in Short. Representative of the first generation G-Shock G-Steel in a steel case. The protective structure of the body is due to the combination of steel and polyurethane – two materials of different density and other physical properties. In this model, the bezel is polyurethane, so that the watch remains both for sports and for everyday use. While reading information from the dial, you can activate the Hands Shift function – when the hands take neutral positions, so as not to interfere with reading data from electronic windows. The watch has a solar battery [charged from daylight]. The time is automatically corrected by radio waves from towers around the world. At night, the analogue and digital zones are illuminated by separate LEDs with automatic activation when the wrist is turned.

The most distinctive specs of GST-W100 *Editorial
— 200-meter water resistance (good for swimming but not for deep diving)
— Tough Solar (CASIO’s original solar-charging system converts not only sunlight but also light from fluorescent lamps and other sources into power)
— Radio-controlled Watch; Multi band 6 (additional way for time sync. This watch receives time calibration radio signals that keep the displayed time accurate)
— Layer Guard Structure (boasts a double-layer bezel construction of stainless steel and resin or resin and fine resin which delivers the hard, sleek beauty of metal while retaining the impact absorption of resin.)

Official Casio Description. 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.
