The GA2100 family of watches was unveiled in 2019, and they’ve since become some of G-SHOCK’s best sellers. The octagonal bezel and boldly raised hour markers are popular design features. They often speak to those who need reliability, performance, and ruggedness when working outdoors, when exploring the wild places in the world, or when serving with pride and honor in the military.
