Ap 15500 black or grey???

[carpro12]

ive been waiting for some time now for my ad to call me for the blue dial but ive come to terms that is not happening so figured im just going to go grey market and not get the blue dial because of the high prem blue dial so need some help deciding what color either the black dial or grey dial also wich do you think will hold its value better due to the premium im probably going to pay..thanks
