I'd have to disagree with you assessment, and the reasons why are:
-The square "Omega" emblem on the clasp seems to be etched or screen printed, not stamped. All the modern style square emblems for reissued bracelets are stamped with the stamping showing on the underside of the clasp (like in the pic from an earlier FS listing).

-I've never seen "70" or "1125/000" text on this bracelet before. I've usually seen "32" as the circled number, and only "1125" on the underside of the clasp
-Also, never seen "Swiss Made" text on the underside of the vintage or modern versions of this bracelet.
Agree with others that the "tinny" and even cheap feeling is not a good indicator of authenticity, but the above design and text discrepancies would definitely cause some consternation.
Good luck with the resolution and do update us on how it works out.
