Not mad. But notice how all the other things you listed have a utility, or benefit they bring to the consumer? Whereas the watch serves zero purpose? Well it does have a purpose, which I already detailed. It's "peacocking" at it's more pure. "Just please look at my watch and tell me it's cool, and understand that I do in fact have a lot of money."
Cars, computers, phones, shades all serve a purpose. And even a necklace or whatnot I can get behind. They at least have been around for ages and are used as a piece of fashion. Giant ugly ass watches don't look good, compared to a nice chain. The fact that Rolex has become synonymous with "expensive watch" tells one a lot. You see a Rolex, you know that guy spent several thousand dollars. Why? Because he wants to simply tell you he spent several thousand dollars. That's the only purpose.
