I only have one auto watch at the moment, I never wore it since I'm waiting for a strap, but I did a test. I took the watch in my hand, and swung my arm like if I was country skiing (30 times back and forth). Then I left the watch on my desk. It kept running for over a week (to my surprise).
I don't think I have an amazing watch, paid under 100$ for it, so maybe you could look dumb for a few minutes like I did and it would solve your problem.
Hmm. With the exception of some very high end watches with unusual mvmts the typical watch either auto or handwind runs about 40 hours fully wound. There are some that go 60 and a few that go a week.
