The GA-2100CM-5ADR is the khaki earth-tone variant of the GA-2100 metallic camo — the warmer, more outdoorsy counterpart to the grey CM-8A. The same original G-Shock camouflage pattern with metallic print sheen, but in a khaki-brown palette that leans into the gorpcore and outdoor fashion space more naturally than the grey. The warm earth tones blend with olive, tan, brown, and natural-fibre outfits — the kind of colour palette that belongs on a trail as much as a city street. Bio-based resin bezel and band derived from corn, with the G-Shock G-mark concealed within the camo pattern.
Module 5611 is identical to the grey variant and the metal-bezel GM-2100: analog-digital with two hands and a day sub-dial, hand shift, 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, Neobrite lume, Carbon Core Guard, and a full auto-calendar to 2099. At 48.5 × 45.4 × 11.8 mm and 51 grams — the same ultra-light, slim profile. Shock resistant, 200-metre water resistant. SR726W × 2, approximately three-year battery life.
At a Glance
Why You'll Love It
- The khaki metallic camo is the warmer, more natural option of the two GA-2100CM variants. Where the grey -8A reads as urban and monochrome, the khaki -5A reads as outdoor and earthy — tan, brown, and olive tones that blend with gorpcore, trail wear, earth-tone layers, and natural-fibre outfits. The metallic print finish adds the same reflective sheen as the grey, giving the khaki camo a sophistication that flat matte camo doesn't have.
- At 51 grams, the GA-2100CM is one of the lightest G-Shocks available — lighter than most smartwatches. The all-resin construction with Carbon Core Guard means you barely feel it on the wrist. Combined with the 11.8 mm slim profile, it's a G-Shock you can wear all day without fatigue, whether you're on a trail, in the office, or moving through the city.
- Bio-based resin derived from corn is used for the bezel and band — a sustainability-conscious material choice that performs identically to standard resin. The earth-tone palette and bio-based material create a coherent outdoor-meets-sustainability identity that aligns with the gorpcore aesthetic the CM series is designed for.
- The hidden G-mark woven into the camo pattern on the bezel and band is G-Shock's original camo design — not a stock military pattern. It's a discovery detail that rewards close inspection.
- Same Module 5611 as the metal-bezel GM-2100: hand shift, world time (48 cities), double LED Super Illuminator, five daily alarms, 1/100-second stopwatch with split time. Full functionality in a featherweight package.
- 200-metre water resistance and shock resistance. The outdoor styling is backed by genuine outdoor toughness — this is a watch that handles trail conditions, not just trail-inspired fashion.
