Ahh i was once in the same dilema.
I came to a conclusion that it may be the same watch or it may not. It varies greatly with paul's stock. Also some photos shown are stolen from other dealers, and he may send you a different watch.
Also you are paying a premium on the service. If the watch arrives scatched, broken, missing, wrong watch, most of the trusted dealers here will gladly offer you support.
For Paul, he sends watch, that is it.....
The extra you are paying is for a piece of mind. With Paul its a gamble. You may win and save 125 bucks or you may lose and have a 200 paper weight.
