Google and Qualcomm are working on a next generation of smartwatches that should be arriving this fall, and more possible details continue to arrive during this year's Google developer conference. Google is expected to finally make its own watch through its internal hardware division, but better make that watches, according to the latest report from German tech site Winfuture.de.

The three watches, code-named Ling, Triton and Sardine, could be differently sized, like Apple's 38 and 42mm watches. Or, maybe one has cellular, and others don't, much like the Apple Watch Series 3. The report says the watches will have GPS, LTE and VoLTE support, and some (or all) will have heart rate sensing and the ability to detect stress levels.
