Post their launch earlier this November, Casio's new Charles Darwin Foundation collab watches have surfaced in new IRL photographs, and while images for the same are already being posted by some buyers online, these are the first showcase images we've seen - courtesy of @geesgshock on Instagram. Thanks to these, we now get to see how the designs look outside of Casio’s promotional renders. These follow the launch details covered earlier, where both watches were confirmed as Tough Solar, Bluetooth-enabled, and built entirely from biomass resin.
The hands-on shots show that the color palettes are somewhat stronger and more complex in real conditions than the product images suggested. The red/orange Rock Crab version is deeper in tone under indoor lighting, with the markers appearing more pronounced due to the gloss on the dial. The crab emblem on the subdial is a great touch - not overly large, but sharp enough to add character without feeling too gimmicky. The matching orange strap has a matte finish that softens the bright red case, and makes the watch feel more wearable than the promo images implied.
On the other hand, the Albatross version comes across as more muted in person. The grey case and strap combination is darker than expected, and the yellow markers pop less aggressively. The subdial emblem for the albatross is cleanly printed and sits neatly within the small register, and the dial texture seems to shift between matte and semi-gloss depending on the angle. The hands-on angles also confirm a subtle color gradient on the dial that’s hard to detect in studio renders.
From a construction standpoint, nothing new appears beyond what Casio announced, but these real-world shots make it easier to gauge how the watches will look on-wrist. The cases have the recognized Casio GA-B2100 shape, and the Tough Solar + Bluetooth combination still anchors the spec sheet. What the hands-on images add is a more grounded impression: these are bright, themed models, but not overly saturated or toy-like.
If you want a GA-2100 model, you can check out the Casio G-Shock GA-2100-1A2ER on Amazon for only $89.
