Omega Caliber 28 guidance

Greetings OF,

New to the forums and thought I'd seek some guidance from the community here. I may be potentially acquiring a beautiful 50s Omega piece but it was mentioned that the cal. 28 movement does not work when wound (was working well a couple years ago). Overall the movement looks rather clean but it is hard to tell.

I'd like to find out how hard would it be to acquire parts for this movement as I couldn't seem to find much information on this particular cal.

Thanks for the help OF 😀

Look again. Under the balance. You need Infos on the omega calibers 280 family. Many different versions. Yours could be calibers 283. Parts are not difficult to find. Looks good from the outside. Factor in an service for around $300 and any problems should be fixed. If the balance does not move at all, the mainspring might be overwound. Easy fix. Good luck ! Achim

Thanks guys.

This does indeed look like it belongs to the cal. 360 family movement, almost similar in all aspects.
Hoping it will be an easy fix!

Except for a 4 discontinued parts. Supplier shows parts are available for it and one discontinued part is readily available.

Other three a small hunt.

Could just need a cleaning or new mainspring as the movement looks very clean
