This is for sale on the bay by a very high rated Omega watchmaker. But the quality looks awful.

Don’t know for certain about this particular bracelet, but it doesn’t look that different in quality from 60s and 70s era Omega bracelets.

Thise aren’t at the same quality as modern bracelets.

If you’re interested in it, I’d ask for pictures of the back of the clasp, where the Bracelet number is stamped, along with other Omega specific markings. That would help in judging the authenticity.

 

Quite genuine.
