Just weeks after being the subject of intense speculation over its entry to the wearable tech market, Microsoft has duly proven that there’s no smoke without fire by unveiling the Microsoft Band.

The wearable device boasts 10 sensors that can track a number of exercise and health metrics, including sleep quality, heart rate, calories, stress and even a person's sun exposure.

As expected, the sleek wristband can be connected to all major mobile operating systems and can operate for two days on a single charge, giving the device a leg-up on devices from rivals Apple and Samsung.

"This is just the beginning of a multi-year vision for Microsoft in the health & fitness and wearables category," the company said in a statement.

"We want to enter this space in a deliberate and measured fashion and as such are launching first in the United States."

Retailing for $199 (€158, £124) on Microsoft’s online store, the Band makes a timely arrival in time for the festive period, with fitness wearables expected to dominate this year’s wish lists.
