A client has sent in this Ebel chronograph. It’s not running and someone has cleaned the dial without applying varnish.
Movement looks to be in good condition.
If the movement looks familiar it’s probably because the Omega 320 is based on the CH27
I start taking apart the chronograph components.
I now start taking the base movement apart.
Here you can see the crown wheel that is situated underneath the train bridge.
Here you can see the gear train layout.
All the parts have been cleaned and are ready to be put back together.
I fit the cap jewels and see that the balance moves freely.
The mainsprings I get from cousins have been a little tricky as the inner loop is too large. I dig out this from my collection and it fits perfectly.
Here you can see the setting/winding mechanics going back in the movement after I fitted the base movement.
After putting the base movement together and seeing it runs well I start fitting the chronograph components.
Movement almost back together.
Before fitting the dial I like placing the movement into the case to see everything is working like it should.
The dial gets a new layer of varnish that will protect it from corrosion.
I have also applied new luminous compound to the dial and hands.
Top quality chronograph movement.
After the movement has settled, I’m happy with the performance!
Great looking chronograph!
