Operation Guide

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

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.

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 DW-5600C also includes accents to the dial. Blue, green, and all-black options offer clean, minimalist color choices.

DETAILS

Carbon Core Guard structure, both strong and light

The shock-resistant structure unique to G-SHOCK protects the module, with a carbon fiber-reinforced resin case offering strength, lightness, and excellent weather resistance.

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

Super Illuminator (high-brightness double LED light) for maintaining watch readability in the dark
