First time Omega buyer - Is this a real Omega watch?

Hi all,

I'm a first time buyer of an Omega watch. It's been a dream to own one since I was younger. I found a used constellation which I love the look of but I need help identifying whether it's legit it or not.

Here are the photos are info shared by the seller.

Thank you in advance!

Seems ok, but the gold cap is a bit too much worn off for that price.

Thanks so much for your reply. What price would be fair do you think? Do you think this is a good first time purchase?

As long as it seems from your expert opinions to be a real Omega watch, I'll definitely make an offer. Is there a recommended price given the pictures and info provided ? (I know the quality isn't great)

Do a search on eBay sold listings for this reference.

Seller randomly blocked me while I was negotiating price with him...... guess I'll hold off and wait like you said! Thanks everyone.

No sharp edges anymore. For me quite important when buying a watch. As its gold cap you also cant remove much material to sharpen them again.

For what it's worth, the c-case connie with the brick link bracelet in gold cap is pretty cool looking. Look for one in the best condition you can find.

Thanks so much for all the replies and guidance friends!
