We have seen a good number of smartwatches this year. More models will debut later this year and in 2015. But most smartwatches offer only a couple of days of battery life. This Onyx E-ink Smartwatch is different. The watch does have a 1.56″ sun-readable display. The watch synchronizes with a phone over Bluetooth. It also offers a step tracker and a three-button navigation system. You will have to wait till 2015 to get your hands on this watch.
