Real yes, real Breitling, I doubt it. Firstly, anything from Turkey, Italy, Eastern Europe, and South America is always suspect until proven otherwise. I think this one was probably a Chronograph Suisse, or something like that, initially and it's been modified with a new crown and breitling script on the dial. The serial number would also be too early for the movement and that style watch if it was authentic so I don't think it is. I'm still not convinced about the Landeron movement ever being installed by the factory because I haven't seen certain proof with a watch that meets all the normal authentic Breitling criteria for the period except the Landeron movement (like one owner or known history watch). There's something a little odd with the hands and dial on this one also. I'd stay away but that's just me.

I think Paul's covered it - this never saw the insider of a Breitling factory. I would add that a genuine 18K Breitling caseback is highly unlikely to need a double caseback.
