The title is very misleading. The technique (RTK) depends on using a second receiver, not just a smartwatch on its own.
Title is fine. The key is the plural, smartwatches. From the actual article:

Oh, that's interesting, I have to read it... Did they set up the smartwatch in a fixed place?
Ah yes, somehow I missed this :-S. Would edit my comment if I could.
