Great pics Pix.
I only wish they would come out with a version that has the accurate colors on the dial.
I seem to remember a post that compares the GMT rep to the gen and the difference (other than the case back) is that the gen has silver numerals as opposed to white on the rep.
I would happily go without the display back and a 7750 for the benefits of the ETA movement.
Also the GMT is less chunky than the chrono in a rep by the look of the specs.
Enjoy it, it's a great watch.
