Here are just a couple. When in doubt ask here before making a purchase. Folded over instead of solid side links. This seller posted the bracelet with a convincing looking Omega bag, except the part number is for a completely different bracelet. Folded links again. This is a correct example, and yes there were plenty made is the USA.
The thing I can't figure out is with all the fakes out there why is it so hard to find a generic BOR bracelet? I'd be happy to put a good quality BOR bracelet on some of my non Omega vintage watches.
