Could be a 1175, but the endlink inside the clasp looks interesting . 22mm will fit for the SM120C or the Flightmaster
It'd be for watches like the Lemania powered auto chronographs, 176.007 and its many and diverse relatives, assortment of divers too, 22mm was common on those larger 70s models
It doesn't look right. I think the mesh is the way to go. I don't like it on the Isofrane either. I do like the 600 on Isofrane best though
Does it say made in Switzerland? Let me guess: it does not. And it does not say Made in Mexico either, right..? Congrats, you are the proud owner of a legit bastard, an American-Swiss bracelet. It is most likely an American-made Omega bracelet form the 70s, probably mid-early 70s, found sometimes on Mk 4.5 and other 22mm cases. It seems to be on a category of its own, not a lot of info about it. Omega USA was making some independent sourcing decision at the time, and they had bracelets and cases made in the US that were not really documented and tracked in Switzerland. My guess is that those were replacement bracelets, but I do not know that for sure, they might have been original as well on some models. Pretty rare piece... Those are my findings, and I'd love to hear more from our members who are way more knowledgeable than your humble servant.
