Declare your commitment to the Galápagos with a G-SHOCK collaboration timepiece created with the Charles Darwin Foundation — two great models inspired by two iconic species inhabiting these gorgeous islands.

G-SHOCK's fourth collaboration with the Charles Darwin Foundation, an organization that engages in environmental conservation activities in the Galápagos Islands, has produced two different partnership watches: one inspired by the Galápagos Albatross and the other by the Sally Lightfoot Crab.

Based on the GA-B2100 with its Smartphone Link and Tough Solar charging, and featuring a band and bezel made with bio-based resin produced from renewable organic resources, the timepieces honour these endearing creatures with environmentally focused functions and materials, vivid colour, and unique designs.

The GA-B2100DF-4A honours the Sally Lightfoot Crab, which lives on the islands’ rocky shores and sandy beaches. Its vivid colouring is captured in the watch’s bold red and orange colour scheme. A playful depiction of the crab raising its claws appears on the indicator hand as well as the band loop. The dial also features a silhouette of the Galápagos Islands.

The case back is engraved with the Charles Darwin Foundation logo and name in Spanish, and the band is printed with the statement “Apoyo la conservación de Galápagos.” (Spanish for “I support Galápagos conservation.”)

These watches also come complete with special, plastic-free packaging, befitting a timepiece collaboration with the Charles Darwin Foundation.
