Dick Tracy would be proud! Toshiba has today unveiled a prototype of its new Computer Graphic Watch: an OLED screen on a traditional watch wristband that can be paired with a smartphone.
Users can make and receive calls, use their phone's GPS for navigation, check their email and surf the web without taking their phone from their pocket or bag.

The flexibility of OLED means users can choose from a range of different styles for their watch's clock readout, with grandfather hands and modern digital styles on display.
