That's pretty much what's going on.
There's a lot of incorrect information, misinformation, a lot of marketing and made-up stories... All being gobbled by a large client base that's eager to build a vintage Rolex collection.
Furthermore, a lot of these watches were doctored back 20-30+ years ago, so the story that "stretched the truth" back in the day has been told so many times that it is the truth today.
