Upgrade the retro look you love with the octagonal GA-2100 line, which inherits the design concept of the very first G-SHOCK, but now with Smartphone Link and Tough Solar power.
Carbon Core Guard Structure
A new carbon core guard structure protects the module by enclosing it in a carbon case. The case is made of fine resin embedded with carbon fibers for outstanding strength and crack resistance.
