Casio has taken a preferred mannequin, made it extra versatile with Bluetooth and photo voltaic, and added three new engaging dial variations (gentle blue, black, inexperienced), plus one black IP chrome steel high case/bezel with a black dial and a white bio-based resin strap (this mannequin carries a slight premium and is on the market solely at GShock.com).

The addition of Bluetooth and photo voltaic makes the watch extra versatile than the GM2100 which doesn’t have these fashionable conveniences.
