I have been looking at this watch on e-Bay. The ones I looked at seem identical, but have different numbers. Such as 2350 or 2350-3. These are not real numbers but used as an example. Are there different grades of co-axial Seamasters made?

Hey Jerry word of advice I bought one thinking it was real even though something just didn't look just right to me. Later I asked someone knowledgable on them he told me it was a replica. I am not saying that one is just beware they are out there like the Rolexes.
