After a successful launch in the UK, Casio has announced its new model in the G-Shock 2100 series is coming to the US too.

The GA-B2100 adds both Bluetooth connectivity and solar power to the classic 2100 design. It is part of the brand's Carbon Core collection too, and comes in retro-inspired colours.

The design of the original GA-2100 was itself inspired by the first G-Shock watch to market - Casio's DW-5000C - so this refresh has 90s appeal. That's also reflected in the colours on offer - black, navy, yellow and green - which stand out as much as the chunky bezel itself.

In terms of tech, the G-Shock GA-B2100 can be connected to a phone through Bluetooth and Casio's Smartphone Link system. It enables the watch to keep accurate time, change over the time zone based on 300 cities, set reminders and even find your phone or watch using the other.

The Tough Solar feature allows the watch to persistently operate when exposed to a reasonable amount of light. Even without exposure, it can last for around seven months on its rechargeable battery with normal use.

In addition, each GA-B2100 is water resistant down to 200 metres. There's also a double LED light to illuminate the time in the dark.

The G-Shock GA-B2100 is available to buy from g-shock.co.uk now, with a US release coming in June. Prices start at £130 / $150.
