You may also want to consider buying without the clone 3186 movement, you only see it when the back is off and it makes no difference to the function of the movement, and you will save around $90.

Luke,
Your friend clearly has an acquired taste for reps - since the explorer II and GMT IIC are, IMHO, two of the best out of the box R@llie reps available. If you go with the GMT IIC, I would consider the ETA movement better value than the Asian Clone with the modified bridge engraving.
Cheers, Lumpy.
