I’ve only seen one before, and it was marked with typical Omega clasp marks. Anyone have any ideas about these? Maybe a country specific manufacture or 3rd party? Sorry they are not perfectly clear.

Omega had several manufacturers for its bracelets, buckles, cases, dials and even some movements (Lemania for chronographs).

It's not unusual to see different markings on several pieces.
