I never understood why Rolexs are SOOO expensive but DAMMMMNNN!! WIZ WON!
Seriously? A Rolex is worth 5-10k easy for their standard models because their the premier swiss luxury brand. A rolex watch is made out of the finest materials and complies with the highest internal mechanical standards set in place (and every watch is checked) by the COSC. It is subjective to say that it Rolex is the best watchmaker and their cost is marked up a certain % like any luxury brand, but they do make some of the finest timepieces in the world. A Rolex should last you a lifetime and then you can pass it down to your son and it will last him a lifetime.
But why one would cost 30k? Because it was probably a one off made custom for either a specific retailer or Kanye himself, probably using exotic metals and jewels such as high quality platinum and crystal clear diamonds.
