Don't force anything on that poor timepiece. The parts combining both winding and time setting (the keyless works) are prone to wearing out with time (a difficult to pull out stem is a sign of this) and replacing broken or severly bent parts can be difficult. As a general rule handwound mechanical watches should be serviced every 8 years.

Most of the time watches "break" as a result of careless users or unqualified repairmen.
