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.

Tough Solar (solar powered)
Easy to operate via smartphone
Easy to see in darkness
-Reminder setting: The watch will remind you of up to five upcoming events, which you set within the app.
