The Casio G-Shock G-Steel (Model GSTB200-1AWC) is an analog and digital men's solar-powered watch combining a carbon core guard structure with a stainless steel case for exceptional durability. The watch features a fixed mineral crystal bezel, black dial with luminous hands and hour markers, and a black resin bracelet with a buckle clasp.

The G-Steel is built for demanding environments with shock resistance, 200m (656ft) water resistance, and a solar movement that eliminates the need for battery replacements. The case measures 49.2mm wide and 14.5mm thick with a 26.4mm bracelet width. A date and day calendar is displayed alongside standard hour, minute, and second functions. The watch syncs via Bluetooth with the G-Shock Connected app for automatic time adjustment.
