From G-SHOCK comes a 2100 model full metal version now with Bluetooth connection and tough Solar technology. The thin module of the GM-B2100 range is made possible by downsizing components without sacrificing Bluetooth® functions, solar power capabilities or other functions. A carbon core guard structure makes this model a thinner design vs other full metal G-Shock watches, whilst maintaining a high degree of impact resistance. The GM-B2100D has a silver coloured stainless steel band and bezel with a sophisticated black dial. Item: 6410138
