Hi, I am looking to buy the 5172 steel, but before I take the plunge I would like to hear from existing owners out there. What are your thoughts about the watch. Is there anything you dislike about it and also service cost for the watch. I also know its a hard model to find. I intend to put my name on the wait list from AD. If anyone knows a quicker way for me to get one, kindly share. Thanks guys.
