New Casio GBM-2100A bold bezel metal watches now available

Casio has released three new G-Shock G-Steel GBM-2100A watches. The GBM-2100A-2B, GBM-2100A-4B and GBM-2100A-8B were revealed in July 2025, when they were confirmed for the UK and Japanese markets.

In the UK, you can now buy the GBM-2100A-2B (blue dial, positive LCD display) and GBM-2100A-4B (purple dial and inverted LCD display) for £229. Here, a 20% discount for students and keyworkers is advertised. In Japan, these two models and a third variant, the GBM-2100A-8B (gray dial and inverted LCD display), are now available for ¥37,400 (~$253).

The Casio G-Shock GBM-2100A analog-digital watches feature Smartphone Link connectivity, pairing to your smartphone via Bluetooth for auto time adjustment and other settings and tools via the Casio Watches app. They support 38 time zones and feature a countdown timer, a stopwatch and five alarms. Plus, these watches can be illuminated with a double LED backlight, and they offer Tough Solar charging.

Each of these 2100 series watches has a patterned dial surrounded by a bold steel bezel, measures 49.3 x 44.4 x 11.9 mm (~1.9 x 1.7 x 0.5 inches) and weighs 72 g (~2.5 oz). Casio has yet to announce when these G-Shock G-Steel GBM-2100A watches could officially launch more widely in Europe or in other regions like North America.
