Casio G-SHOCK 2100 Series – GA-B2100DF-1A

Charles Darwin Foundation Collaboration Model

The GA-B2100DF-1A is a special collaboration model created with the Charles Darwin Foundation — honoring the unique wildlife of the Galápagos Islands. Inspired by the majestic Galápagos Albatross, this limited-timepiece blends environmentally conscious materials with G-SHOCK toughness and meaningful conservation-driven design.

Built on the GA-B2100 platform, this model features Smartphone Link connectivity, Tough Solar power, and bio-based resin components made from renewable organic resources. Vivid colors, symbolic details, and engraved branding celebrate the beauty of the Galápagos while supporting ongoing environmental protection efforts.

Design Overview

This collaboration marks the fourth partnership between G-SHOCK and the Charles Darwin Foundation, an organization dedicated to conservation activities in the Galápagos Islands. The GA-B2100DF-1A is themed after the Galápagos Albatross, one of the islands’ most iconic and largest birds, with a wingspan of over two meters.

Symbolic design elements include:

  • Indicator hand shaped after the wings of the albatross

  • Yellow accents representing the bird’s beak

  • A map of the Galápagos Islands printed on the dial

  • Band loop featuring an albatross silhouette

  • Case back engraved with the Charles Darwin Foundation logo and name

  • Band printed with “Apoyo la conservación de Galápagos.”
    (Spanish for “I support Galápagos conservation.”)

Eco-conscious packaging without plastic further reinforces the model’s environmental message.

With a blend of unique design motifs and advanced G-SHOCK functionality, this collaboration celebrates the breathtaking wildlife of the Galápagos while promoting real-world conservation.
