In addition, these watches feature a slim module with an optimized component layout to retain the compact watch face for which the 2100 line is known, yet still deliver enhanced functionality. Combining this with the Carbon Core Guard structure, which protects the module with a carbon-fibre-reinforced resin case, provides both shock resistance and a compact case with the same length and width as the GA-2100.
The dual-layer dial construction highlights the dimensionality of the LCD and inset dial. Meticulous attention to detail is evident in the metallic finish on the inset dial ring, which gives the dial a look of enhanced texture. For these additions, Casio returns to the classic colors first used in the G-SHOCK 5600 line with reproductions of the yellow, green, and blue of the DW-5600C-9BV (released in 1987, EOL), DW-5600B-3V (released in 1987, EOL), and DW-5600B-2V (released in 1987, EOL). There are also two black colourways: a black model with a gray dial, which is in the same color scheme as the DW-5600C-1V (released in 1987, EOL) from the original 5600 series, and an all-black model.
