Robustness, reliability, maintenance
We’re talking G-Shock. So we hit it (reasonably). Drop test at 1.2 m on smooth concrete slab — 5 drops per model, 10/13/2025, Compans zone. Zero dysfunction. Micro-marks visible on bezel of the GA-2100 (matte black resin); the DW-5600 copes better visually, its more rounded bezel “bounces back”.
Mineral glass for both. Light scratches after controlled rubbing against a plastered wall (20 cm, 3 passes, 10/12/2025). Nothing dramatic. It’s difficult to polish: long live protection if you’re the type to hit. Straps: standard resin, sturdy fittings; wide center distance compatibility, RAS in three years of use.
Classic trap: the gray market. If you chase the economy at all costs, you open the door to counterfeits. Read and keep: recognizing a real G-Shock with concrete proof. That’s non-negotiable.
Carbon Core Guard: gimmick? No.
The carbon cage of the GA-2100 is not an empty argument. It stiffens the architecture and allows the contained thickness. My manual twists (approximate stress 3–4 Nm, home bench, 10/14/2025) show less lateral bending than a conventional resin. It doesn’t feel much on the wrist, but that explains the finesse. And therefore the comfort under the sleeve.
Price, value, status
Do. The GA-2100 rides on aesthetics; the DW-5600 lives up to the legend. In terms of perceived value and limited series, bet instead on desirable variations (shades, collabs). I detail cases in G-Shocks that are really increasing in value — no promises, trends.
Price levels observed in Toulouse (October 12–14, 2025): classic GA-2100 often between €99 and €129; DW-5600E often between €59 and €99. Yes, things are moving in promotion. And yes, collaborations are exploding. That’s a bad idea if you’re looking for a tool that lasts: don’t pay twice the price for one color.

Iconic status: why we care about it
The DW-5600 is the historic silhouette (heir to the DW-5000). It tells the story of G-Shock culture. The GA-2100 tells the story of 2019 and beyond: modernity, textured dials, urban fashion. Two stories, two clienteles… which intersect. So: no bad choice, just a different priority.
Shopping experience: simple, authentic, without traps
My advice: try both on the same day, five minutes each, fitted to your bracelet hole. The brain cuts quickly. Note how the watch slides under the sleeve, and whether the lighting suits you in the store. To understand the overall context, history and families, reread history and key points for purchasing G-Shock — and come back with a firm budget.
Authenticity: favor official resellers or controlled marketplaces. Check the stamped warranty card, the exact reference on the label (GA-2100-xx, DW-5600-xx), the protective film on the bottom. If the price is “too good”… be wary. In short, be cool in the act of purchasing, warm on the wrist afterwards.
Choose quickly, but wisely
Urban use + shirt, style sensitivity, want a watch that “speaks” without shouting? GA-2100. Basic sports use, need a chrono readable in half a second, love of clear numbers? DW-5600. You get the idea.
And if you want to stay in the “square” spirit with comfort options (solar + radio-controlled), we have set concrete benchmarks in the article on the best 5000 in our opinion, the GW-M5610. I know, I already talked about it above. Assumed repetition — useful.
Useful specs (without overhead)
- GA-2100 : analog + digital, 5 alarms, 24 h chrono, 24 h timer, double LED, Carbon Core Guard, 200 m, SR726W×2 batteries (~3 years). Typical dimensions: 48.5 × 45.4 × 11.8 mm.
- DW-5600 : digital, 1 multifunction alarm, 24 h chrono, 24 h timer, backlit EL, 200 m, CR2016 (~2 years). Typical dimensions: 48.9 × 42.8 × 13.4 mm.

Clear summary
- Do you prefer fine and current style? GA-2100 (11.9 mm, Carbon Core Guard, “Casioak” presence).
- Do you prioritize immediate reading of the timer? DW-5600 (homogeneous EL, dedicated screen, straightforward buttons).
- Multiple alarm(s) : GA-2100 for 5 reminders, DW-5600 if one is enough.
- Tight budget : DW-5600 more accessible, GA-2100 for a notch of perceived finish.
- Robustness : draw in real use; the GA seems a little more rigid, the DW is less visually striking.
- Thickness/handle : GA-2100 slides better under jacket, DW-5600 “fits” more tool.
- Value/collections : desirable series OK but don’t pay for the hype. Aim useful.
