Not every automatic hand-winds
A classic Seiko 7S26 is automatic-winding only. Turning the crown does not wind the mainspring, and that behavior is normal.
A change in feel matters
If a watch that normally hand-winds suddenly feels rough, slips or will not turn, stop forcing it.
The crown may not be the root cause
Stem damage, keyless works and winding-train components can all create a winding complaint.
Automatic reserve problems are different
A watch may hand-wind correctly yet fail to build power through wrist motion. That points toward a different part of the system.
