G-SHOCK announces latest addition GA-B2100

G-SHOCK announces latest addition GA-B2100 series with five new GA-B2100 watches. They are the first in the iconic 2100 line equipped with Smartphone Link connectivity via Bluetooth and solar charging capabilities. It was first released in 2019, the base-model watch GA-2100 was a contemporary interpretation of the very first G-SHOCK, the DW-5000C. This watch has a simple and stylish design that proved popular around the world, especially among younger consumers.

The new GA-B2100 has Bluetooth connectivity and a solar charging system, bringing this new GA-2100 shock-resistant watches a whole new level of convenience. Smartphone pairing (using the dedicated CASIO WATCHES app) via Bluetooth delivers accurate timekeeping. The Tough Solar charging system effectively converts light from fluorescent lamps and other sources to power the watch, thus eliminating the need to replace the battery regularly.

These GA-B2100 watches feature a slim module with optimised component layout to retain the compact watch face that the 2100 line is known for, yet they still deliver enhanced functionality. Combining this with the Carbon Core Guard structure that protects the module with a carbon-fibre reinforced resin case, this provides both shock resistance and a compact case with the same length and width as the GA-2100.


Design wise, the dual-layer dial construction highlights the dimensionality of the LCD and inset dial. There is meticulous attention to detail, it is evident in the metallic finish on the inset dial ring that gives the dial a look of enhanced texture.


For the new GA-2100 watches, Casio returns to the classic colours 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 colour scheme as the DW-5600C-1V (released in 1987, EOL) from the original 5600 series, and an all-black model.
