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!
Hola. he intentado reparar este calibre pero me cuesta mucho poner la tapa enciam de la rueda de escape..¿alguna recomendación? saludos y gracias.
Hello from Romania!
If I buy the barrel (complete) from cousinsuk, does it come oiled or do I have to disassemble it and oil it myself?
Thank you, and congrats on you work!
Yes, it comes lubricated, and you can just use it as it is.
Looks nice, that little Citizen.
This watch reminds me of my day-date auto Citizen in the early 1970s.
What age is this one?
I own several Citizen’s with type of movement…I’m not convinced of the winding efficiency of the unidirectional rotor. Maybe it’s how I wear them 😉
I have one of those, but with a green rather than blue tint 😉
