I must say I've had the oppertunity to put the TT YM on at my ADs,and it is a truly stunning watch.
A couple of observations:
The dial seems to have the ability to change "hues" if you will from Blue to almost Black depending on how the light strikes.
The watch seems to fit a little lower on the wrist,very very comfortable.
JJ, I would take this in a New York second over the TT Sub.
Oh,and I can't get over how STRONG some of those sales people can get when they want to pry a watch out of your hands!!
