Seiko Japan has previewed a new watch with Bluetooth. Though it's a bit oversized and odd looking, the features are admirable. When paired with your mobile, the watch will display the phone's signal and battery strengths. It can also show the caller id for an incoming call which is especially useful when wearing a Bluetooth headset. Other features include SMS display, built in ring tones and vibes, and the ability to switch your phone to silent mode.
