I know exactly how GPS works. I know that many GPS devices rely on cellular connects to simulate high accuracy. Small GPS units give iffy-position data information when they work with satellites.
So for all the ultra runners using their GPS watches on mountains and trails, what makes you think the Timex is any less of a watch? It has not only GPS but also cellular connectivity for when it's available. It will be the ultimate athlete's watch (so far).
