Fake Omega Bracelet?

Hey all, I recently picked up a speedy on a very definitely incorrect-for-this-model omega signed bracelet, but I am wondering if it's really an omega bracelet at all. The clasp fells a bit cheap compared to a similar one I've got, and while the link structure looks the same from a distance, it's definitely different than my only other reference. (also pulls a bit of wrist hair) There are no markings on the lugs as it's been modified by someone in the past to fit a different case.

Any opinions on this thing?
