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 organisation 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 GAB2100 with its Tough Solar charging and bio-based resin, the environmentally focused functions and materials honour the rich diversity of nature in vivid colour and unique designs. Choose the one that speaks to you — the GAB2100CD-1A4 in two-tone red and black, which are the colours of the Galápagos marine iguana, the only iguana in the world that swims in the sea; or the GAB2100CD-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 honour the natural environment in which these spectacular creatures live.

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

Presenting partnership watches designed with the Charles Darwin Foundation, an organisation that engages in environmental conservation activities in the Galápagos Islands. This third collaborative release features two models, one featuring the Galápagos marine iguana and one the Galápagos penguin, two endearing creatures represented in vivid colours and unique designs. Based on the GAB2100 with its Tough Solar and bio-based resin, the environmentally focused functions and materials of these watches celebrate the rich diversity of nature.

Galápagos marine iguana

GAB2100CD-1A4

The colours of the Galápagos marine iguana — the only iguana that swims in the sea — are represented in two-tone red and black. The indicator hand and band loop feature a stylised iguana sunbathing on rocks, the dial bears a map of the Galápagos Islands, and the wave pattern on the inset dial recalls the sea.

Galápagos penguin

GAB2100CD-1A7

The charming black-and-white coloration of the only penguin seen in tropical waters at the Equator is represented in the bezel and band. The dial features a map of the Galápagos Islands, while the wave-patterned inset dial and diving penguins on the indicator hand and band loop complete the look.

Special features to commemorate a special collaboration

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