About this watch
The Casio G-Shock GA-B2100DF-1A is a special collaboration model created in partnership with the Charles Darwin Foundation, inspired by the iconic Galápagos Albatross. Based on the popular "CasiOak" GA-B2100 platform, this limited-edition model combines G-Shock's rugged performance with a meaningful conservation message. The black dial features yellow accents inspired by the albatross's beak, while the dial incorporates a map motif of the Galápagos Islands. The band and bezel are produced using environmentally conscious bio-based resin materials.
Built with G-Shock's Carbon Core Guard structure, the watch offers exceptional durability while maintaining a slim profile. The 48.5 × 45.4 × 11.9 mm case weighs only 52 grams, making it comfortable for everyday wear. It features 200-meter water resistance, shock resistance, mineral crystal protection, and Neobrite-coated hands and markers for improved visibility. The distinctive octagonal bezel design has become one of the most recognizable modern G-Shock silhouettes.
Powering the watch is Casio's Tough Solar technology, eliminating the need for regular battery changes. Bluetooth smartphone connectivity through the Casio Watches app provides automatic time adjustment, world time synchronization, reminders, phone finder functionality, and easy watch settings. Additional features include world time for 38 time zones, a 1/100-second stopwatch, countdown timer, five daily alarms, dual LED Super Illuminator lighting, full auto-calendar, and power-saving mode.
Among G-Shock enthusiasts, the GA-B2100DF-1A is particularly appreciated for its subtle black-and-grey color scheme, positive LCD display, Tough Solar charging, and Bluetooth functionality. Owners frequently note that the watch looks even better in person than in photos, with the yellow accents adding character without compromising everyday versatility. Its combination of collectability, practical features, and environmental theme makes it one of the more distinctive releases in the GA-B2100 series.
