Casio G-Shock

This series downsizes the GA-2100 to create a simple and slim design.

The octagonal bezel, flat face, simple bar hour markers, and carbon core guard structure that are distinctive features of the GA-2100 are now available in a compact configuration.

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.
