Everyone knows that Rolex is among the best names in luxury time pieces, but do you know how to tell if one is real? We do! With a high-ticket item like this "Rolex Cellini Danaos Gold Watch", our first strategy was the fishing technique. With a retail price of over $8,000, we tried asking $6,500 for this gently used piece. After a month, our best offer was only $4000. We then asked our consignor to trust us and we put it up for auction starting at just $9.99 and it closed at $4,650. My consignor later confided in me that the very jewelry shop he bought it from only offered him $2500 for it. Everyone made out! Smart consumers know that good name brand items always hold their value and it never hurts to save your documentation and original packaging.
