Casio G-Shock Charles Darwin Foundation watches, Digi Mart USA News: Two new Casio G-Shock watches tied to the Charles Darwin Foundation are reportedly on the way, according to a publisher report from Notebookcheck. The Japanese watchmaker has previously collaborated with the science and conservation organization four times, with the 2025 releases being the GAB2100DF-1A and GAB2100DF-4A.
Thai retailer Hatyai Nalika has listed two new models on its online store: the GA-B2100CDF-2A and the GW-B5600CDF-4. As with earlier products in this collaboration, each watch’s theme is based on an animal found in the Galapagos Islands, where the foundation focuses its research.
According to the report, a leaker known as Geesgshock on Instagram suggests the GA-B2100CDF-2A could be inspired by the blue-footed booby, based on its blue and beige color scheme. The source describes this as speculation only, and leaked images indicate the hybrid watch will feature a miniature bird image, similar to the earlier GA-B2100DF-1A.
Leaked images of the GW-B5600CDF-4 point to a flamingo theme. The digital watch reportedly has a bright coral resin bezel and case, a red accent strap loop, and a camouflage-style frame around the display.
Casio is expected to officially announce the GAB2100DF-1A and GAB2100DF-4A watches in December 2026, according to the report. Based on the release timeline of older models, the report suggests these products could roll out globally in early 2026. Notebookcheck did not independently verify these details, and the timing and model information should be treated as unconfirmed until Casio makes an official announcement.
