Declare your commitment to the Galápagos Islands with a truly special collaboration celebrating the Charles Darwin Foundation. The case and band are made of bio-based resins to honor the commitment to the environment that G-SHOCK and the foundation share.

This commitment is also captured in the dial design, printed watch glass, band loop, and LED backlight display — all inspired by the hammerhead sharks that call the Galápagos home.

The case back is engraved with the Charles Darwin Foundation logo and name in Spanish, while the band printed with the Spanish phrase, Apoyo la conservación de Galápagos, proclaims your commitment to protecting these precious islands.
