Our take on the Casio G-Shock Full Metal GM-B2100D-1A Men's Watch

The GM-B2100D-1A is Casio's full-metal take on the 2100 line, the octagonal-bezel G-Shock inspired by the 1983 DW-5000C. The case, bezel and band are stainless steel, with a screw-back case and a slim analog-digital module. It adds Bluetooth phone pairing and Tough Solar charging on top of the usual shock resistance, LED light and stopwatch functions. It suits buyers who want a steel G-Shock that reads dressier than a resin one, but shoppers should know some units sold online are described as replicas with non-working Bluetooth.
