You could also ask why people wear fake watches at all. You want to make your surroundings believe
that you are a rich and successful person. The real problem is not the watches you wear, but the people who wear them.

Nobody will be able to tell for sure that it is a fake watch at a distance of just one metre. But a person who can't
afford an expensive real watch with a high degree of certainty will be recognized at a much greater distance.

It is the appearance of the person, his style, his movement, his language.

If that does not fit, then no apparently expensive watch will help. And certainly no forged papers.

You can wear a fake watch without hesitation if you can buy the same watch as a real one at any time.
