[Media Release] Casio to Release Charles Darwin Foundation Collaboration G-SHOCK Watches

    Featuring Designs Inspired by Creatures of the Galápagos IslandsMade with Bio-Based Resin for Less Environmental Impact

    Casio Computer Co., Ltd. announced this week the release of new additions to the G-SHOCK brand of shock-resistant watches. The three new GW-B5600CD watches are the brand’s latest collaboration with the Charles Darwin Foundation, an organization that engages in environmental conservation activities in the Galápagos Islands.


    The Charles Darwin Foundation is an international non-profit organization committed to conserving the natural environment of the Galápagos Islands. The organization is involved in a range of activities, including surveying the Galápagos Islands’ marine and terrestrial life and ecosystems and promoting island nature conservation efforts. The latest collaboration model marks the second partnership between G-SHOCK and the Charles Darwin Foundation, following the first in 1999.


    The new GW-B5600CD shock-resistant watches feature designs incorporating silhouettes of creatures that live in the Galápagos Islands, along with the rich natural environments where they live. While based on the GW-B5600, a timepiece equipped with radio wave reception and Tough Solar charging capabilities, the new GW-B5600CD watches feature a bezel and band made with bio-based resin produced using renewable organic resources.


    Each of the three watches features a face with a unique design motif: a hammerhead shark in an ocean environment for the GW-B5600CD-1A2; a Darwin’s finch amid the foliage of a Scalesia forest, one of its preferred habitats, for the GW-B5600CD-1A3; and a Galápagos giant tortoise in a rocky location, one of its preferred habitats, for the GW-B5600CD-9. Silhouettes of each featured creature also appear on the LCD when the backlight is illuminated.

    The Charles Darwin Foundation logo is engraved on the case back, and a Spanish-language statement meaning “I support Galápagos conservation” is printed on the band. A portion of the proceeds will be used to support the Charles Darwin Foundation’s conservation activities.


    Charles Darwin Foundation

    Founded under the auspices of UNESCO and the IUCN, the Charles Darwin Foundation is an international non-profit that has been at the forefront of science and conservation action in Galápagos since 1959. Our scientists are driven by a common purpose: to safeguard the unique biodiversity of one of our world’s most important natural treasures. At present, CDF manages over 25 research, conservation, and educational projects across land and sea, working hand in hand with the Galapagos National Park and international NGOs looking to maximize sustainable impact. Our work is only possible thanks to the extraordinary community of donors who support us every day. Thank you for making an impact with us.
