Here's one on ebay, I think the same as I showed, with original crown (not sure if from this model exactly, but at least with logo), way more polished but I belive case is the same, the dial also.

Not the same case at all. Totally different lugs.

For me they are just heavily polished but it’s only theoretical discussion 😀 thx for your opinion

The movement was made by Omega in Switzerland. The gold case was not. It was made by a local contractor under license by Omega. This was frequently done to save on customs.

There are no Swiss hallmarks or “Swiss Made” on the case as would be required by Swiss law.

Hope this helps,

Nope, completely different. The OP watch has curved lugs, the one on eBay has triangular lugs.

One more thing, if it’s not Swiss case but made in Japan, then is it possible that the crown here is not signed because of that and I found out that crown was plated because I can see silver under the cover.

The crown should be signed.

Possible, but not likely. And you’ve just found out why. Crowns are parts that are designed to wear out. When they do, most watchmakers can’t always source factory correct replacements.

A lot like tires or windshield wipers on a car.

Here are some more photos. Case itself weights 32g, I cannot open the case because I’m afraid of damaging it and o was not able to visit watchmaker today. But I think it’s most likely 18k gold Japan version, no outside hallmarks as on the one available on eBay and the crown seems to be gold plated replacement with signs of wear. Dial is interesting, good condition in my opinion, inside cal. 283. I bought it and I’m very happy 😀 it’s 35mm without crown.
