At CTIA 2010 CNET takes a look at the W Phonewatch from Kempler & Strauss.
Kempler & Strauss W Phonewatch
On the last day of CTIA We stopped by the Kempler & Strauss booth to is new watch phone. The W Phonewatch isn't just a Bluetooth extension of your cell phone, it's a complete quad-band world phone. The unlocked device has a SIM card slot and a microSD card slot. Even with those features its face isn't larger thank a standard wristwatch. It measures 2.4 inches long by 1.7 inches wide by 0.70 inches thick and weighs 2.5 ounces.
It does have a speakerphone, but it's really designed to be used with the included Bluetooth headset.
The Phonewatch also supports text messaging. The display is surprisingly responsive, though we suspect tapping out anything, but the shortest messages would be tedious. Also, the tiny text means that this is a not a device for the visually impaired.
