The GAC-2500 is inspired by the original G-Shock DW-5000 envisioned as a minimalist analog watch. It lacks some of the usual G-Shock functions such as a timer and alarm, but it has some more recent features that include a magnetic holding structure with a self-adjusting Shock Release Hand and the Second Hand Sleep option which can extend battery life to approximately five years. The LED light is an amber color instead of the usual white.

The G-Shock GA-2100 was launched in 2019 and quickly reached classic status in just a few years, achieving a place alongside such long-running models like the DW-5600 from the ’80s, the DW-6900 from the ’90s, and the GA-110 from the ’10s. The GA-2100 is akin to a DW-5600 in an analog-digital form. The bezel and band of the watch borrows their shapes from the classic DW-5000 origin model, and the octagonal bezel has earned it the nickname “CasiOak” among fans.
