The first image of the OnePlus fitness tracker appeared

The image is of sufficient quality, but still, this does not prove its reliability. On the other hand, you can hardly expect any unique design from such a device, even if it is created by OnePlus. Also, the company has recently not even tried to distinguish its smartphones outwardly among dozens of others. 

OnePlus Band (tentative name) is similar to many other activity trackers in this format. There is a fairly large colour screen, a quite ordinary strap, and you can also see three dials, although there should clearly be more of them.
