G-Shock GA-2100 CasiOak

The GA-2100 took the octagonal bezel from Casio’s 1983 original and slimmed the case to 11.8mm — which is how it picked up the CasiOak nickname and became the G-Shock most people buy first. Carbon core guard structure, 200m water resistance, and a battery measured in years rather than days.

The range splits three ways once you look closely. GA-2100 is resin and quartz. GM-2100 adds a forged stainless bezel and weight to match. GA-B2100 adds Tough Solar and Bluetooth, so it charges from daylight and sets itself from your phone.
