Yeah, I even took the crystal off and gave a tiny nudge to se if it was maybe just lightly corroded in place. It looks fine inside, so it must be a gear thing going on. Wehn I get slightly more brave I'll take a look at the works.
The darn thing sets perfectly, the balance wheel runs like crazy, so it must be something on the order of; wrong stem, shifted works, something not meshing somewhere or maybe a gear corroded in place.
I have dissembled a dynabeat, which is sightly different I know, but it may give me a clue before I go tearing into this watch which is nicer and certainly a keeper.
