A Rolex, new in 2019, would still have a few years on the warranty.

If 40 winds only gets you an hour, the mainspring has come loose, or it's taken a pretty good knock and broken a jewel that keeps the pivot from turning (or some such damage).

The first would be covered under warranty, the second, or any damage, would need to be paid for just like anything else that gets broken.
