Samsung trumps iPhone with smartwatch launch

Samsung has unveiled a smartwatch that works as an accessory to its Galaxy smartphone as rival Apple prepares to launch its latest iPhone next week.

With a small screen offering functions such as photos, hands-free calls, and instant messaging, the smartwatch was launched to coincide with the start of the IFA consumer electronics trade show in Berlin.

Meanwhile, Apple is set to unveil the iPhone 5s at an event at its California headquarters on Sept 10.
