I have an old Soviet mechanical wristwatch that cost 3β¬ on an Eastern German flea market.
Compared to other watches it sounds like a Diesel tractor, the bezel rotates freely and the wristband pulls my arm hair out.
When I wear it, it's too fast and when I don't wear it, it's too slow.
But I only wear it during the day and take it off at night, and that way it's been keeping perfect time for 15 years.
