Where abouts in NY for watch

I am heading to Newyork in a couple of months and i am thinking of treating myself to a new watch,could anyone point me in the right direction,i will be staying in mid town Manhattan.It would be great if there was somewhere that i could view/compare prices in order to get the best value price.
Thanks in advance.

Why don't you just Google any Outlet Malls which may be accessible from where you're staying - you can buy serious stuff there at discounted prices, certainly a lot cheaper than purchasing anything in Manhattan!
