Aiya, u get a famous rich person to wear a fake watch, everyone will also think it a super expensive limited vintage watch.
If you are nobody, poor and self-inferior person, given the chance to wear a real PP watch or any class rolex, people will think it fake.
It the overall that bring up a person image (if you care a lot) and what you wear or dress or live is what people make up of, and not yourself.
U only live once, if a watch can make you happy, it worth every single cent.
If you need to struggle to keep up a public image, even it free, it not worth it.
