Omega bracelet clasp without 'professional'

[tclaw]

I came across an omega bracelet but the clasp looked a little dated and I wasn't able to find anything similar on Ofrei's site for replacement parts. Has anyone ever seen a gen clasp like this?

That is what the original 42mm PO came with.

Any suggestions on ways to verify authenticity via pictures?

In my experience you can determine its pedigree when you remove/replace links.
