Expert ScoreRead review

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.

G-Shock GA-2100 Rating By G-Central
The G-Shock GA-2100 is recommended for those who want a simple, compact, and lightweight analog-style watch. The digital functions like world time, stopwatch, and timer, may also come in handy, but the small LCD makes using them more challenging than a full digital model.

CONS
  • LCD display is very small.
  • Not all models have Neobrite lume.

  • No auto activation setting for light.
  • Needs maintenance (battery replacement) every few years.
