Hi guys

Someone knows if my citizen have a screwdown crown??

I cant unscrew it to clean the case

Thanks you so much

I guys, how's going on?

Im writing because i was servicing an old timex and it had a bit of corrosion under the dial (i feel humidity made that corrosion)

So i scratched the blue/green corrosion with my tweezers but im worried about how it can develop over the time.

Do you feel its safe to leave as is? Or better to apply something? Maybe nail polish?

Happy to hear your thoughts

Hi guys, someone know if that mainspring is still usable?

I serviced an old poljot and when i dissassembled the mainspring i feel i assembled wrong. So now it have this shape.

First it was ok (when i dissassembled it). Can i still use this one?

Its a Poljot movement. And if someone can tell me how i have to assemble the mainspring i will be so glad. Its the first time i dissassembled one…

Usable mainspring?
