G-Shock Duo Chrono Military Series GA100BBN-1A

From G-SHOCK, the watch brand that is constantly setting new standards for timekeeping toughness, comes a basic series of models with monotone black coloring and a cloth band. Powerful functions come packed in a configuration designed to stand up to rigorous work environment along with a CORDURA?* nylon fabric band that is stronger than nylon. This type of band is made of materials that are both light and very strong, while providing extremely high resistance to stretching, wear, and tearing. The band ring is made of stainless steel. This lineup provides a selection of three distinctive models, all done in G-SHOCK black: the DW-5600 that is classically G-SHOCK, the DW-6900 which has been used for a large number of collaboration models, and the GA-100 featuring a big, bold case and anti-magnetism. The monotone coloring of these watches give them a bold and powerful look that is suitable for any situation where the going might get tough.
