There is an update to the watchOS that might fix this but I thought I'd put it here just in case.
before I returned my watch I had to reset it, I noticed that I was unable to do this so had to get sighted help.
You go into settings/general/reset and tap on reset this watch, then a screen comes up asking if you're sure, a voiceover user, at least with the version of wawatchOS I was using won't be able to flick to the buttons for ok and cancil.

same here
I am having the same issue. Did you ever find a work-around?
in case you still haven't found a solution
What actually worked for me was a two-finger swipe up when you hear the message that all settings will be erase. That will get you to erase all. I hope this helps if you encounter that situation again.
