Samsung unveils Galaxy Gear smartwatch accessory

Samsung has unveiled a smartwatch with a colour screen that can show alerts, be used for voice calls and run apps.

The Galaxy Gear smartwatch had been highly anticipated since the firm is currently the world's bestselling smartphone maker and has beaten Microsoft, Apple and Google to unveil such a device.

Analysts warned that a decision to limit the watch to working as an accessory to other Galaxy Android devices might limit its appeal.
