Had one of those on my left hand for years, sometimes painful but mostly just there. Even had surgery set up, but when I read there's 50% chance it'll come back, I cancelled. When I retired I quit wearing a watch and it went away within a month.
The watch had a Speidel twist-o-flex band which was tight enough the watch wouldn't move around and get caught on something while working, but it wasn't constrictive. It most certainly could be a coincidence, just retiring may have done it.
