Not just how deep the numbers are, but the width of the numbers, that photo above is a great comparison. if you could lift the "18" off the rep dial, it would fit inside the "18" of the genuine. Just no comparison.
Here is a better photo of the gen insert on the watch.
I didn't realize how much off the GMT was until I added the genuine bezel/insert, dial and crystal. I know that the ICHS drives lots of folks away, but only during that brief period when the hour hand is over the GMT hand is that a "tell", the others are all the time! BTW the photo in my post above was taken before the dial was changed to genuine.
