From G-SHOCK, the toughness watches that continue to evolve in search of ultimate strength, this digital-analog combination model inherits the concept of the first-generation models, while being even thinner. Inherits the octagonal shape that was also used in the first-generation model. A combination model developed with a simple design that eliminates waste while maintaining a tough structure.

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.
