Expected to officially launch on March 16th, Casio looks to make your next G-Shock an accessory that works hand-in-hand with your smartphone. The G-Shock GB-6900 uses Bluetooth 4.0 to connect with your device to display all incoming notifications (calls, emails, & text messages). With the GB-6900 you can also set alarms and set your phone’s ringer to vibrate all from your watch. Armed with a two-year button battery the GB-6900 will set you back around $231. I got my eye on the Black model, I know the Red one will interest Ceasel. So who’s buying?
