You know how Dick Tracy used to use his wristwatch as a two-way radio? Even though we most certainly have the technological capacity for a two-way wrist communicator, that technology never caught on. Maybe we just prefer talking into cell phones or wireless headsets than our wrists.

The Sony MBW-100 Bluetooth Watch is a definite tread back into Tracy territory. The MBW-100 uses Bluetooth technology to interface with your cell phone. So if you have an incoming cell phone call, the watch face shows you right away. If you wish to reject the call, just hit a button on the watch. The watch also notifies you of an incoming text message, and informs you when you wander out of cell phone range. You can even access your phone’s music player to play, pause, and fast forward through tracks. This is something that most users do from the remotes on their headphones, but hey, why not incorporate the watch in your audio entertainment experience?

The MBW-100 watch is designed to be very sleek, with a stainless steel body and scratch resistant crystal window. It has an analog style, with quartz movements for exact time keeping. The screen that informs of callers and other info is a clear OLED display.

Like most new watches, it is water resistant (up to 30 meters). Unlike most watches, the MBW-100 comes with a “charging clip”. Other stats say that its Bluetooth functionality is only up for 7 days, and Analog time keeping is up to 7 additional days. I’m wondering if that means that the watch has to be charged like your cell phone. I don’t know about you, but I’m not used to charging my watch. Normally, I just let the little battery in it do its job. Sony apparently expects its users to develop a new habit of watch-charging. I suppose if you needed this device’s useful functions, I suppose you would quickly develop the watch charging habit.
