The only reason I'm including the first shot is because it's pretty:
Second shot shows fitment of gen pro 2 bracelet. I had to keep the rep part that connects directly to the watch case because the gen parts that it came with were for a different ling and they were a bit curved. The rep part that serves as the intermediate between the case and the bracelet fits perfect and is completely unnoticeable. Here are some shots of how the bracelet fits. I need to adjust the bracelet a little still but immediately the bracelet seems to weigh about 20% more than the rep.
In the third image, the gen is on the left and the rep is on the right in both the top and bottom pictures. I apologize for the wear and tear on the rep. As you can tell, all engravings appear more crisp and the breitling stamp doesn't seem as "pushed in" on the genuine. On the rep clasp the part where it says Breitling 1884 is literally pushed in a little bit but on the rep the stamping is much more clear. It's also important to note that even the gen clasp feels as though it should not be twisted in such a way that it would be stress on it at awkward angles when it is open. Also, the push pin (where one would adjust the tightness of the clasp) sits perfectly flush in the holes where as the rep does not. All cuts, corners and angles of the gen seem to be machined with greater attention to detail. The closing thingy on the clasp itself (on the gen) is flat where as on the rep it seems to take the overall curved shape of the rest of the clasp.
Lastly, gen is on top and on the left. Again, the attention to detail on the gen is noticeable.
