Joel sent in this lovely little Citizen with the 8210A movement. It beats very feebly, and the timegrapher can’t pick up the signal.
And here is the culprit – a deformed hairspring.
Before doing anything else to the movement, I reshape the hairspring and test it.
Now I take the movement apart for cleaning.
There is a huge amount of grease under the barrel, and the barrel and lid have separated.
A nicely constructed bottom plate with a quick-set date.
Now everything can go through the cleaning machine. I managed to get hold of a complete barrel with mainspring for only £7!
I put the base movement back together, and now we can see how my hairspring reshaping went…
That’s not shabby at all for a Citizen!
A very nice little watch!
