This REP is a miracle! For a very reasonable price the result is impossible to tell from a GEN. The bezel is a masterpiece, and all the details are in one word: PERFECT. There are only two details that (without opening it) allow you to recognize it from a GEN: the movement of the bezel is a tiny bit less smooth (still with the same exact sixty soft bidiractional clicks!) and (of course!) you can move the 24H hand instead of the 12H for the GMT function (but if you want Andrew sells other movements that do this right). For the rest it's really, really perfect!!
