From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes the GA400HR-1A model.G-SHOCK brand colors are used as the main case and band colours. The overall base colour of the watch is black, for a look of unrefined toughness, with splashes of red for lettering and on other case components. A bi-colour 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. The base model is the big case GA-400 model which is known for its dominant, bold appearance.
