Previously we have seen many things that never got developed by Microsoft, from countless Lumia devices to the Surface Mini, now we got some info about an Xbox watch.
The alleged device that is shown in the image above was supposed to be developed in 2013 with a release date in mid-2015 but more info was never released by Microsoft. The front has a 1.5-inch display and on the back, there is, what looks to be, a heart rate monitor. The source also states that this watch could be charged wirelessly through a magnetic connector.
The product in the image is defined as a prototype so a final product would differ in shape and design. Could it be the predecessor of the Band?
