Seiko Japan is currently developing a unique watch that is able to connect to your cell phone via Bluetooth. Still a prototype though, but it is already able to display phone’s network’s signal strength, battery life, and new message indicator. Furthermore, with a special software from Seiko installed on the phone, the watch can also display the message’s subject, along with the name of the sender. Hold on, there’s more. Upon receiving a call or SMS, the watch will act like a cell phone by playing a melody (polyphonic ringtone?) and even vibrate. And since it won’t be nice to hear both your phone and the watch ringtone, the watch is equipped with the capability to silent your phone’s ringtone. Wow.
