We already know about the Microsoft Band 2 which was announced back at Build 2015. But the only color option that was available in the market was Black, and there was a speculation made after the Panos Panay’s Surface live Tour held back in June 2016,  that Microsoft may indeed announce a successor as the Band 3, with a WHITE color option as well. But it never made it and made us think, it was exclusively for internal use only at Microsoft.
Now, a Chinese forum Nokibar has managed to post a video with the rare device. Take a good look at the video below.

From the video, you can quickly spot a few differences like the gold color around the touch instead of the silver as on the original Band 2.
In case you are not aware, Microsoft has confirmed that the Band 2 is being removed from the market, which is quite unfortunate.
