Can this crown be repaired?

[panchoskywalker]

Hello, I have this crown which belong to a citizen and the small tube in which the stem is screwed in is broken so I bought theses small things on aliexpress but there's not enough thread to screw them in.

Can you think about anyway this can be fixed?

Hi. Have you tried unscrewing it.  Tighten it in a pin vice you me get lucky.  If not it’s a replacement.

I've tried to unscrew it  but it doesn't work and I am afraid to break it.

It's already broken, nothing to lose.

Source a replacement from the likes of Cousins uk or the American material suppliers.   Esslingers, Otto Frei, Timesavers etc.

The crown I have is 6mm in diameter and 2,5mm thick. Stem is 0.8mm and the tube that comes out from the case is 2.5mm in diameter.

I've found this crown on cousin, do you think it would fit?

Your existing crown looks to have a stem extender already fitted to it, which is broken. So if you can unscrew this part from the existing crown, you may be able to use the crown. It's probably superglued on, so use heat to destroy the bond. You would then need a stem extender or a completely new stem cut to length.

The new stem you found at Cousins looks OK, as long as the number 8 thread fits. You are still likely to need a stem extender or a new stem though, because of the missing length.

I tied but it just broke, it was only 1 piece together.

I think you have a long pipe crown with a oring on the pipe. Citizen and Seiko normally use this type of crowns.

You can check Cousins website.

But are you sure the stem is 0.8mm. If so, you'll have to look at their tap 8 range.

Stem is actually 9.

I've identified this one on this listing:

The only thing is that it doesn't say how thick it is.
