The Pebble smartwatch has gone on sale on Amazon.com.
The watch, known for its success on the crowdfunding website Kickstarter, is available for purchase from the Pebble Technology Corporation through the website for $150 (£91).
The Pebble, which is compatible with both Android and iOS devices, can view notifications, control music players and be customised by downloading new apps and appearances. The battery is said to last between five and seven days on a charge and connects via Bluetooth.
The watch is yet to be released over here in the UK.
