The octagonal form of the 2100 line, now with Smartphone Link & Tough Solar

We’ve added Smartphone Link and Tough Solar capabilities to the 2100 line. All in the same efficient minimalist design and slim profile, the watches now feature Bluetooth® for pairing with a smartphone and Tough Solar charging functionality. Color options include the classic hues of the first color G-SHOCK watches. We are proud to present a new standard combining appealing aesthetics and expanded functionality.

Lineup

Simplicity of design
with octagonal form:
The same sense of size,
with added functionality

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.

Dial featuring enhanced
texture as well as
improved functionality

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.

Homage to the first
color G-SHOCK
models

We have brought back the classic colors first used in the G-SHOCK 5600 line for the case and band, inspired by the concept of getting back home. The color scheme of the DW5600C also includes accents to the dial. Blue, green, and all-black options offer clean, minimalist color choices.
