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.

Our fourth collaboration with the Charles Darwin Foundation, an organisation 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-1A is inspired by the Galápagos Albatross, one of the largest birds on the islands, with a wingspan of over two metres. Its graceful glide on rising air currents is depicted in the shape of the indicator hand and on the band loop. A map of the Galápagos adorns the dial, accented with yellow details evoking the bird’s beak.

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.

Charles Darwin Foundation partnership watches inspired by creatures that live in the Galápagos Islands

This release marks the fourth collaboration with the Charles Darwin Foundation, an organisation engaged in environmental conservation in the Galápagos Islands. It features two models: one inspired by the Galápagos Albatross (waved albatross) and the other by the Sally Lightfoot Crab, two endearing creatures, represented here in vivid colours and unique designs. The base model is the GAB2100, featuring Tough Solar and bio-based resin. Both functions and materials reflect a commitment to environmental responsibility.


Charles Darwin Foundation

The Charles Darwin Foundation is an international nonprofit organisation that operates the Charles Darwin Research Station. It is the first international organisation to engage in conservation activities in the Galápagos Islands, starting in 1959. Currently, it has over 100 staff members from all over the world involved in a range of activities, including surveying the Galápagos Islands’ marine and terrestrial life and ecosystems, promoting island nature conservation efforts, and providing environmental education to local residents.

Galápagos Albatross | GAB2100DF-1A

The Galápagos Albatross is one of the largest birds in the Galápagos Islands, with a wingspan of over two meters. Its graceful glide on rising air currents is depicted in the shape of the indicator hand and on the band loop. A map of the Galápagos Islands adorns the dial, accented with yellow details inspired by the bird’s beak.

Sally Lightfoot Crab | GAB2100DF-4A

The Sally Lightfoot Crab lives on the rocky shores and sandy beaches of the Galápagos Islands. Its vivid body colours are expressed in the bold red and orange colour scheme. A playful depiction of the crab raising its claws appears on the indicator hand and the band loop. The dial is also adorned with a silhouette inspired by the Galápagos Islands.

Special features to commemorate a special collaboration

The case back is engraved with the Charles Darwin Foundation logo, and the band is printed with the statement “Apoyo la conservación de Galápagos.” (Spanish for “I support Galápagos conservation.”) These watches come complete with special, plastic-free packaging.

Key resin components used in the bezel and band are made with bio-based resin, a material expected to help reduce environmental impact.
