The GRUNGE CAMOUFLAGE Series is inspired by grunge fashion from G-SHOCK, which continues to evolve in pursuit of toughness.
The base model uses two models from the metal covered series: the classic GM-5600 and the octagon bezel GM-2100.
Inspired by the grunge fashion that emerged from vintage clothing and rock music culture in the 90s, the metal bezel is specially processed to have a pattern that looks like the metal has peeled off, expressing the coolness of grunge fashion.
The dial (GM-2100GC) and glass printing (GM-5600GC) are painted metallic to create a style that matches the metal bezel.
The band uses biomass plastic
This model has colors that are easy to style, from dress to casual occasions.
