The Casio Galápagos x G-Shock collaboration watches are on the way to the UK. These two GA-B2100 series timepieces have been designed in partnership with the Charles Darwin Foundation. These products were revealed in mid-October 2025 and have since become available to pre-order in Japan.
Now the Casio G-Shock GA-B2100DF-1A and GA-B2100DF-4A watches have been listed at the brand’s online store in the UK. In this market, they will each retail for £159. The company notes that these products are excluded from voucher codes. They are expected to be released in the UK at some point in November; to get an email notification when they launch, you can “sign up now” with an email address from the product pages.
The GA-B2100DF-1A is inspired by the Galápagos Albatross, with the bird shown on the feature indicator and the band loop. This watch has a black resin casing and strap, with yellow accents as a nod to the albatross’ beak. The GA-B2100DF-4A is designed around the Sally Lightfoot Crab, with a red resin bezel around the black dial, and a bright orange resin strap. As with the other watch, the crab is used on the indicator and the strap’s loop.
The GA-B2100 is a hybrid watch, with two analog hands said to remain accurate to within 15 seconds each month. A hands-shift function ensures that the digital display, showing information like the date, is not obstructed. This is a Bluetooth watch, with users able to access some settings and tools through the Casio Watches app on their smartphone. It also supports world time and offers Tough Solar Charging. On top of this, on-watch features include a 1/100th second stopwatch, five daily alarms, a countdown timer and hourly time signals.
Casio has yet to announce plans to bring these new Galápagos x G-Shock collaboration watches to other European countries. Whether or when they could be released in the US is also unknown.
