From G-SHOCK, which strives for toughness, comes a Black & Red Series that makes the most of G-SHOCK colors. G-SHOCK brand colors are used as the main case and band colors. The overall base color of the watch is black, for a look of unrefined toughness, with splashes of red for lettering and on other case components. A bi-color molding process is used for the band, which makes it possible to create a band that is black on the outside and red on the inside. The flashes of red from the inside of the band when putting on or taking off the watch is a bold statement of G-SHOCK identity.
Base model is the big case GA-400 model that really stand out on the wrist.
The brand colors of this new model capture the very essence of the G-SHOCK spirit of toughness.
