Go bold and confident with a strikingly straightforward G-SHOCK in high-contrast black and white. 
Beginning with a base of G-SHOCK jet black and then bring in a bright dial finished in brilliant white vapor deposition. The monochromatic statement is a study in contrasts—matte black against glossy white. This abundantly cool design is available in five different models.
Choose your favorite — the GA-700 with front button design, the GA-100 or GA-110 with large case, the triple-graph design of the DW-6900, or the GA-2100 with octagonal case.
