If that's a redial it's a damn good one. The 12 - 6 crosshair runs through all the right places. The only way to tell if it's original or not is to look at it under a loupe and see if the ink is raised or flat and how crisp the lettering is. I'm nearly sure that's original.
Have to say that looks excellent, it even has the trapezoid shaped date magnifier in the crystal which is a nice touch, great to see the interest growing in Universal Geneve
