The cult 'smart watch' Pebble has finally arrived - offering email, music controls and text message alerts via an 'E Ink' screen on the wrist.
The watch, priced at $150 (£95), was a project from crowd-funding site Kickstarter. Site donors raised $10.2 million for the hi-tech gadget, which pairs with smartphones via Bluetooth.
The Pebble offers users notifications for emails, texts and calls, and also offers running apps and music controls.
The watch's 'E Ink' screen uses the same technology as the paper-like screens in e-readers such as Amazon's Kindle, making it easy to read in sunlight.
The first 500 backers of the watch have already been sent their techno-timepieces, but Pebble has now gone into mass production, with 1,000 being produced a day according to gadget news site Pocket-Lint.
"Pebble is the first watch built for the 21st century," say its creators.
"It's infinitely customizable, with beautiful downloadable watchfaces and useful internet-connected apps. Pebble connects to iPhone and Android smartphones using Bluetooth, alerting you with a silent vibration to incoming calls, emails and messages."
"Apps bring Pebble to life. Cyclists can use Pebble as a bike computer, accessing the GPS on your smartphone to display speed, distance and pace data. Runners get a similar set of data displayed on their wrist. Use the music control app to play, pause or skip tracks on your phone with the touch of a button."
Users can select different watch faces using a paired iPhone app.
