Product Description

Upgrade the retro look you love with the octagonal GA-2100 line, which inherits the design concept of the very first G-SHOCK, but now with Smartphone Link and Tough Solar power.

While maintaining the iconic octagonal form of the GA-2100 inherited from the very first G-SHOCK, the GA-B2100 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.

Solar-powered timekeeping with Bluetooth® for enhanced accuracy and reliability
