I was just offered the following bracelet, but I'm not sure about the markings on the clasp. I seem to recall that there's such a thing as Omega bracelets that were made in the USA, but I've never actually seen one.

The only other examples of this reference that I could find on the web, all had markings that resembled what I'm familiar with (i.e. No USA text, Omega symbol in triangle, some number such as 11 or 32 in a circle).

What do you guys think? Authentic or not?
