The GM-B2100 is the full-metal version of the CasiOak, G-Shock's octagonal analog-digital line. The case and bracelet are stainless steel, the dial is solar-charged, and Bluetooth links the watch to the Casio Watches app for automatic time correction and phone finding. It suits people who want a tough everyday watch with a steel look rather than a resin beater. Against the resin GA-2100 it is heavier and more formal; against pricier steel G-Shocks it keeps the same module and solar movement for less.
