Casio G-Shock GA-2100 Lineup Charles Darwin Foundation Collaboration Model Carbon Core Guard Structure Bluetooth© Solar Powered Watch GAB2100CD-1A7 GA-B2100CD-1A7

Show your love of the Galápagos and the Charles Darwin Foundation with a G-SHOCK inspired by animals living in these gorgeous islands.
This is our third collaboration with the Charles Darwin Foundation, an organization that engages in environmental conservation activities in the Galápagos Islands, and it features two different partnership watches inspired by the Galápagos marine iguana and the Galápagos penguin.
Based on the GA-B2100 with its Tough Solar charging and bio-based resin, the environmentally focused functions and materials honor the rich diversity of nature in vivid color and unique designs.
Choose the one that speaks to you — the GA-B2100CD-1A4 in two-tone red and black, which are the colors of the Galápagos marine iguana, the only iguana in the world that swims in the sea; or the GA-B2100CD-1A7, a charming black-and-white design for the sweet Galápagos penguin, the only penguin in the Equator’s tropical waters.
For both models, the case back is engraved with the Charles Darwin Foundation logo, and the band is printed with the message “Apoyo la conservación de Galápagos” (Spanish for “I support Galápagos conservation”).
These singular timepieces come in special plastic-free packaging to honor the natural environment in which these spectacular creatures live.
