Well, finally she lives!
Found a complete FHF908 movement (watch head), picked it up from the post office earlier. Out the case and ready for stripping.
Stripped it down, cleaned everything and built back up around my original main plate. Used the centre wheel jewel from the donor movement (as this was one of my possibilities for the locking up)
On the way back up
Everything free (see the escape wheel spinning)
Balance back in and she sprang to life, jewel out for cleaning.
Back in and oiled
Self winding back on
Dial and hands
And re-cased
Time set and on the wrist in the sunshine
