Casio G-Shock watch brings iPhone connectivity to your wrist

The GB6900AA will be available in four colors.

For some people, the cellphone has replaced the simple wristwatch. However, you may be tired of whipping out the smartphone to tell time, only wishing that your watch could do more, and do all that while able to withstand the rigors of an active lifestyle.

There is a watch for that: The Casio G-Shock GB6900AA. Using Bluetooth 4.0, it syncs to your iPhone and will provide email, phone call, and calendar notifications. It is arguably not as sophisticated as some other smartphone-linking watches, but the G-Shock does make efficient use of its power, which comes from a traditional button-cell CR2032 battery.

Aside from the traditional “watch” features, the G-Shock can be calibrated to vibrate on notifications which can then be silenced simply by double-tapping on the screen of the watch. The watch also serves as a tether to alert you if it should lose a connection and fall out of range of your iPhone. The G-Shock Bluetooth retails for $180.00, is available in four colors, black, brown, white and silver/blue, and is compatible with the iPhone 5 and iPhone 4S.
