I have a Garmin Forerunner 935. The first problem was that because it's just giving turn directions and not showing a map (and tbh, a proper map on that screen size and on a wrist that's moving while running wouldn't be especially practical anyway), I missed turns a lot any time there were multiple possible options within a short space.
Then, when I had eventually just given up on relying on the watch and would stop, pause, get my phone out, and look at it for directions, the fact that it was trying to do GPS basically caused the watch to entirely crash. That's definitely a device-specific bug, but it's one that only showed up due to my workarounds to inherent limitations of the form factor.

Ah OK, it works differently on my watch. I actually have a simple route-map on the watch when using navigation and it works pretty well.
