Make a bold, powerful statement with the Ignite Red line in the iconic black and fiery red that embody the ultimate toughness of the G-SHOCK brand. We have injected a few of our flagship models—the octagonal GA-B2100 with Bluetooth and solar power; the oversized, solar-powered GAS-100; the GA-100, GA-2200 and GA-700 with signature oversized case—with the strength and passion of the black and red G-SHOCK brand colours. Deep, blazing red accents against striking, dark black give these watches, and the wrist that wears them, a kick of cool confidence.

Specifications
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.
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.
