The GA-2100CM-8ADR is the grey metallic camo edition of the GA-2100 — the streamlined octagonal G-Shock dressed in G-Shock's original camouflage pattern with a metallic print finish that elevates the camo from matte military to something with sheen and sophistication. The grey palette sits squarely in gorpcore territory — urban outdoor fashion that blends technical utility with street style. The bezel and band are made with bio-based resin derived from corn, and the G-Shock G-mark is cleverly concealed within the camo pattern on both surfaces.
Module 5611 is the same platform as the metal-bezel GM-2100: analog-digital with two hands (hour, minute) and a day sub-dial, hand shift for unobstructed digital reading, world time across 31 time zones (48 cities), 1/100-second stopwatch with split time, 24-hour countdown timer, five daily alarms, double LED Super Illuminator (separate LEDs for face and digital display), Neobrite lume, and a full auto-calendar to 2099. Carbon Core Guard structure protects the module. At 48.5 × 45.4 × 11.8 mm and just 51 grams, the GA-2100 is one of the lightest and slimmest G-Shocks available — the same 11.8 mm profile as the metal-bezel GM-2100, but 33 grams lighter because the entire case is resin. Shock resistant, 200-metre water resistant. SR726W × 2, approximately three-year battery life.

Why You'll Love It
- The metallic camo print is what sets this apart from standard camo G-Shocks. The grey camouflage has a metallic sheen — a reflective quality in the print that shifts as light moves across the surface. It's not matte military camo; it's fashion camo with a metallic finish that reads as sophisticated rather than tactical. The grey-on-grey tonal palette works with gorpcore, urban outdoor, and monochrome streetwear — essentially any outfit where texture matters more than colour.
- At 51 grams, the GA-2100CM is one of the lightest G-Shocks you can buy. For context, the metal-bezel GM-2100YRA is 84 grams and the Bold Camo DW-6900CF is 67 grams. The all-resin construction with Carbon Core Guard keeps the watch featherweight without compromising shock resistance. If you want the 2100's slim octagonal profile without any metal weight, this is it.
- The 11.8 mm slim profile is identical to the metal-bezel GM-2100. The GA-2100CM slides under a shirt cuff, sits flat on the wrist, and doesn't catch on sleeves. Combined with the 51-gram weight, it's one of the most comfortable G-Shocks for all-day wear — you forget it's there.
- Bio-based resin made from corn-derived polymer is used for the bezel and band. It's the same material used in other recent G-Shock releases — produced using renewable organic resources to reduce environmental impact. The sustainability angle is part of the gorpcore identity: outdoor fashion with environmental awareness.
- The hidden G-mark is woven into the camo pattern on the bezel and band — a discovery detail that reveals itself on close inspection. G-Shock's original camo design, not a stock military pattern.
- Hand shift, world time (48 cities), double LED, 5 daily alarms, Carbon Core Guard — the full GA-2100 spec sheet in a 51-gram camo package. The functions don't scale down with the weight.
