While maintaining the iconic octagonal form of the GA2100 inherited from the very first G-SHOCK, the GAB2100 now also has Smartphone Link and Tough Solar power capabilities. It also employs the Carbon Core Guard structure to preserve a similar fit on the wrist as the original model.
The dual-layer dial construction highlights the dimensionality of the LCD and inset dial. Meticulous attention to detail gives the dial a look of enhanced texture, especially the different surface treatments we apply to the dial face and inset dial.
