The smart watch will track a wearer’s heart rate, steps, calories burned, and other key health attributes thanks to a number of sensors embedded in the device. Most importantly, the device will work across different mobile platforms and will also boast a battery life of more than two days of regular use, according to the report.

Microsoft CEO Satya Nadella is trying to change the fortune of its company, which is looke less bright than in the past considering the strugling sales of PCs, the very slow expansion of Windows Phone and the fact that ARM's 64-bit processors are on the way and set to dominate almost all devices.

Nadella wants to make his company’s product offerings available across all devices.
