You are going to need to work with a watchmaker to find a replacement. Your watch was originally sold in the USA and the 14K case was made there.
Omega made hundreds of styles of these ladies watches and crystals were not interchangeable on most of them. You will probably need to have one custom made.
Your watchmaker can remove the bezel and send to a company that specializes in replacing crystals. There is one in the U.S. called CrystalFit. There may be similar companies in Europe, but I don’t know them.
Good luck with the repair,

Thank you for the answer. I think I will send the watch to Omega in Switzerland(I talked to an authorized service center from Budapest and another from Budapest, and both said the same thing, and that is that the watch is too old, and only at the service in Swiss I can fix my problem).
I contacted CrystalFit also (they said that they can help), but i can't find to many reviews, and the reviews I had found on this forum, are not to good.
It will likely cost more than the value of the watch to have it serviced at Omega. I would try and find a recommended independent watchmaker in your country.
Here are a couple of well known parts suppliers in Europe that may be able to fit a crystal:

I think the problem you will have with them and also with Omega is that your watch case was not produced by Omega in Switzerland. Thenwatch may have a non-standard crystal size (non-metric) that may never existed outside the U.S.
I don’t know if Omega has the ability to custom make a crystal to fit your watch case. You will need to ask them. I can tell you that they will only do this as part of a full service and it will be very expensive. Probably in excess of €1,000.
I still think that CrystalFit is likely your best alternative, especially if you can get a watchmaker to remove the crystal from the bezel and take precise measurements. At least you’ll only be gambling the relatively minimal cost of the crystal, plus postage and customs.

To send it to crystalfit, means to send to whole watch, because the bracelet is made with the case, and that means almost all the gold. I don't know what to do, because of the negative review I have seen.
I guess you can always find a bad review online, maybe it's true or maybe it's not. But many people have used crystalfit. I don't think you need to send the movement and dial.
Maybe you should reach out to the German companies I sent. They may do that sort of work, or have the proper part. I’ve heard that Ernst Westphal in particular can be miracle workers for some watches.
I took a closer look at your pictures and I now see that you are correct, there is no removable bezel to this watch. You would need to send most of it to the U.S. for repair of just the crystal.
