I originally thought I wanted a sub too when I started on this board. After reading all the posts of "nice sub, is it real?" I decided to go with something else. My choice was the Omega Planet Ocean ETA. Followed shortly by the Bond watch. Both are very accurate reps of the original.
I suggest the Planet Ocean as a first watch for two reasons. One, it's a cool watch that is considered "affordable" by most people. Unlike a Rolex. No, "is it real?" crap to deal with. Two, the new bond movie comes out in a couple of days and you'll have the same watch that he does. You'll get many compliments on the watch, guaranteed.
By the way, my next watch is a Panerei.
