From G-SHOCK, the GA2100 ana log-digital 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 its Carbon Core Guard Structure where a highly rigid fine resin containing carbon fiber is used for the case material. This edition is done in the original color scheme of the DW-5000C with touches of G-SHOCK red, representing the passion to take on challenges; blue, symbolizing excellent water resistance; and yellow, signifying outstanding shock resistance.
