Movement looks to be in good condition.
Nice amount of gunk.
You can see the setting/winding mechanism.
I start taken apart the chronograph layer.
Movement cleaned and ready to be put back together.
I fit a new mainspring.
I fit the cap jewels and see that the balance moves freely.
Here you can see the gear train layout.
Base movement almost back together.
Movement ready for dial and hands.
I put the movement back into the case.
Watch is running like it should.
The minute recorder spring broke and a new one is readily available as the Omega 321 is based on CH27.
Movement completely back together and looking great.
