The gadget is a smart watch that will passively track a wearer’s heart rate and work across different mobile platforms. It will also boast a battery life of more than two days of regular use, sources close to the project say.
This would give the device over twice the battery life of current smartwatches like the Galaxy Gear and the Moto 360.
Microsoft hopes to have the wearable on the market before the lucrative holiday season. In May, Forbes reported that Microsoft was working on a smart watch that drew on optical engineering expertise from its Kinect division, and which would sync with iPhones, Android devices and Windows Phones.
Apple's own wearable device the 'Apple Watch' is scheduled for release in early 2015. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
