Just recently we saw some real life phones of HTCs upcoming smartwatch. Which is rumored to be canceled now, but today a new HTC Vive device(fitness tracking band) carrying the model number 2PYV100 have been passed through the FCC(link to the corresponding FCC gov document). Sadly, the documents do not reveal many details about the device but according to the FCC listening, it will be a global device.
As you can see in the image, the device have a bunch of health tracking sensors with a circular design. The device also has RF antennas which mean it also has wireless functionalities. We assume that HTC may announce the device in MWC2017.
