Casio would start selling a new range of G-Shock branded watches this year.
This new series G-Shock GB-6900 would come with Bluetooth LE connectivity which would let them interact with a compatible smartphone.
The watch would be able to show you incoming calls and text messages. In addition, you would also be able to control some features on your phone from the watch itself.
Consider this as a very limited version of a device like the Motorola ACTV. The price is expected to be in the range of USD 230-240.
