Casio G-SHOCK GA-2100-1A1

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 DW-5000C models, while being even thinner.
Inherits the octagonal shape that was also used in the first-generation DW-5000C model. A combination model developed with a simple design that eliminates waste while maintaining a tough structure.
Also achieves a thickness of 11.8 mm thanks to a highly rigid fine resin containing carbon fiber for the case material.
Uses a characteristic G-SHOCK blackout color.
