The thing is that with most gen owners, they are not WIS, they treat the watches as jewelery, so whatever happens to catch their eye, goes on their wrist.
Members over here with reps, most the people on the forums, research the heck out of what they buy, before buying them, in the process getting educated about gens and reps alike.
I started out with reps, and transitioned to gens because i realized how much i loved the watches and decided to splurge on the gens.
chances are that most gen watch owners out there know little more then the name of who makes the watch, you won't find many people that go yea, i have a 1680 on or a 1665.
