hi everyone,
todd here, been away for some time due to recovery from a bad injury.
i am a reasonably skilled hobbyist, not a watchmaker.
currently i am working on a Hampden model 307 that is in near mint condition but won't wind.
i have the movement disassembled and everything looks good.
when i test the motion of the clutch assembly, and clutch lever with a bench key with the top plate off everything works properly.
however, when i reassemble the watch the clutch lever will not move the clutch into the winding position.
i am at a loss here.
something is obviously binding but i can't find it.
any suggestions would be greatly appreciated.
i am attaching a pic of the clutch from my microscope that shows it is in good condition.
thanks everyone
todd
