The fan-favorite 'Casioak' gets two key upgrades

Upgrade the iconic look you love with the new octagonal GA2100 line, which inherits the color stories and design concept of the pioneering G-SHOCK from 1983, but now with Smartphone Link and Tough Solar power.

While maintaining the iconic octagonal form of the GA2100 inherited from that 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 applied to the dial face and inset dial.
