New Casio G-Shock watch with mini animal indicator coming soon

Two new Casio G-Shock x Charles Darwin Foundation watches are on the way. The Japanese watchmaker has collaborated with the science and conservation organization four times before. As a reminder, the 2025 releases were the GAB2100DF-1A and the GAB2100DF-4A.

Now, Thai retailer Hatyai Nalika has listed two new G-Shock x Charles Darwin Foundation watches at its online store. The model numbers listed are the GA-B2100CDF-2A and the GW-B5600CDF-4. As with older products from this collaboration, each watch’s theme is based on an animal which can be found in the Galapagos, where the organization focuses its research. 

According to reliable source Geesgshock on Instagram, the G-Shock GA-B2100CDF-2A might be inspired by the blue-footed booby, given its blue and beige color scheme, though this is just speculation for now. Images of the watch shared by the leaker in a post (below) indicate that this hybrid watch will feature a miniature image of a bird, as was the case for the older GA-B2100DF-1A. Meanwhile, leaked images of the G-Shock GW-B5600CDF-4 indicate that its theme is the flamingo. This digital watch has a bright coral resin bezel and watch, a red accent strap loop, and a camo frame around the display. 

Casio is expected to officially announce the G-Shock x Charles Darwin Foundation GAB2100DF-1A and GAB2100DF-4A watches in December 2026. Based on the release timeline of older models, these two products could roll out globally in early 2026.
