I've finally managed to have a look at the green GMT , as around here they only launched a few days ago.
I'd have to agree that the dials on the GMTs are by far the best, in my opinion much nicer than the regular diver ones. I kind of feel like TAG missed the boat by not using the GMT dias on the divers as well.
I don't know exactly why, but the pattern on the diver dials is much more noticeable, and the waves kind of have a silverish/metallic sheen on the tips/edges.
I'm hard pressed to say which GMT looks better, I love both. The green is really amazing, but there's not much in it between the two.
I'd rate them : Green GMT, Blue GMT, Blue, Green.
As others have mentioned the green diver doesn't come across well in photos, it looks grayish in photos, but it's a type of moss green, don't know how to describe it.
