[G-Shock Bluetooth] GA-B2100 — Both Strength and Lightness

GA-B2100-3A with the deep green of the first color wrapped around the case and band. It uses a tough solar with Bluetooth® that ticks the time more accurately.

The GA-B2100-2A is a reproduction of the “first color” blue that was first used in the 5600 series, and has a classic design.

An all-black model with a minimalist coloring throughout. The simple design that easily fits into any styling is attractive.
