The sleek and bold Casio G-Shock GBM-2100A-2B and GBM-2100A-4B watches have officially made their way to Casio’s UK store. First surfacing in rumors back in June 2025, these impressive timepieces were later announced for Japan. Now, UK customers can look forward to snagging these eye-catching watches, retailing at £229. However, the exact release date remains a mystery. For those eager to grab one, signing up for a stock alert via email might be a good move.
Interestingly, the UK market won’t see the third variation, the GBM-2100A-8B with its white dial, for reasons yet unknown.
These watches boast a striking steel bezel, paired with vibrant dials featuring neobrite elements. With a durable resin casing and black band, each watch measures approximately 49.3 x 44.4 x 11.9 mm and weighs about 72 grams. Not only are these watches shock-resistant, but they’re also water-resistant up to 200 meters. Added convenience comes in the form of Tough Solar charging, pushing battery life well beyond the typical seven months.
Equipped with Bluetooth connectivity, these timepieces can pair with the Casio Watches app, offering features like world time across 38 time zones, a 1/100th second stopwatch, five daily alarms, and a countdown timer. The hybrid format includes a double LED backlight and a handy hands shift function to ensure the smaller digital display is always visible.
As for availability beyond the UK, it’s still unclear if these models will launch in broader European markets or the United States. Enthusiasts will need to stay tuned for further announcements.
