Go from strength to strength. Make a bold and confident statement with a G-SHOCK in striking black and gold. 

The all-black body, tough as any G-SHOCK, glitters with gold-colored accents and mirrored textures for a look that is totally bold yet utterly cool. 

Choose the GA-100GGB-1A9 or GA-010GGB-1A9 with watch face gleaming all over in the unmistakable color of gold, thanks to the radiant gold-colored vapor deposition and gold-colored mirror LCD. The band and case are finished with a glossy coating for a sleek, lustrous look. 

Or opt for a watch that showcases the distinctive large face design — the GA-010GB-1A9 with indexes finished in gold-colored vapor deposition, or the GD-010GB-1A9 with LCD perimeter ring finished in gold-colored vapor deposition.
