"Halfbeak" is the code name for HTC's upcoming Android Wear powered smartwatch?8
The watch is expected to feature a round 360 x 360 resolution display. Add to that the support for Android Wear, and well, that's about all the rumor mill has for us at this time.
HTC has sent out invites for an event to be held on September 29th. We expect to see the HTC One (A9) aka the HTC Aero unveiled that day. But the invites say "The World best meets the best" which seemed to hint that the company would be introducing two high-end handsets on the 29th. Perhaps that second device will be a smartwatch instead.
