Apple Watch: Apple unveils smartwatch

Apple has unveiled its much anticipated smartwatch - the Apple Watch - its first new product line since the first iPad and the death of Steve Jobs.

The device runs apps, acts as a health and fitness tracker and communicates with the iPhone.

Although many companies already sell competing products, experts note that Apple has a history of entering sectors relatively late and then changing their direction with influential devices of its own.
