Casio G-Shock GA-B2100

Popular for its resemblance to the Audemars Piguet Royal Oak, Casio's G-Shock GA-2100 gets a big upgrade this year with the addition of Tough Solar and Bluetooth connectivity. On top of the previous model's features, the new GA-B2100 model can be powered by virtually any source of light while a Bluetooth radio allows for the watch to connect to any smartphone to stay on time no matter where you are in the world. The watch also features 200M water resistance, a 38 time zone world timer, a stopwatch, countdown timer, alarm, a double LED light, and up to 18 hours of battery life with the power-saving function enabled. 

The watch will be available in Japan this May and a US release has not yet been announced.
