The G-Shock Solar Bluetooth GMB2100GD-5A Full Metal Digital-Analogue Stainless Steel CasiOak is not to be missed! G-Shock has outdone itself with the construction of the G-Shock Solar Bluetooth GMB2100D-1A Full Metal Stainless Steel watch packed with features in a combined Digital-Analogue setting. The octagonal bezel and dimpled band bring us back to an era of excitement, when Casio released its first-ever G-Shock, this time with the addition of a full metal exterior, screw-back case, and a one-touch 3-fold clasp. In true G-Shock style, it’s incredibly tough and aesthetically brilliant with all the technology that's required of a timepiece.
