I've conducted experiments like this myself and that one dude is a perfect example of how people react.
Most People can not tell the difference. Even well versed watch enthusiasts.
I have handed people replicas and said "this is real" and people will talk about the quality and how good Rolex, Panerai, or Omega does in putting together a watch and they'll talk about how it will last a lifetime.
I handed people a real submariner and said "this is an expensive rep" (I did this to 7 people) and asked "what do you think? How close is it?" and all 7 people were like "pfft I can tell right off the bat. This is junk. Just toss it out. You think this is an expensive rep? You got beat".
So when that one dude with the RM is like "oh yeah now that you mention it this feels cheap" is bs. Lol.
