5. Hublot Big Bang – $5 Million
If Piaget showed us anything it’s that if you want to increase the value of a watch you should stick a lot of diamonds on it. This is a formula Hublot has followed to a tee. The Swiss-based maker took one of their ‘standard’ Big Bang watches as a template and went about finding the right sized diamonds to design and make a very high-end version. The result – a watch with 1282 precision cut and fitted diamonds, more than 100 carats of baguette diamonds and six emerald cut diamonds weighing more than 3 carats each. The final price was a whopping $5 million. Too much for most of us, but not Beyonce Knowles. The singer bought one for husband, Jay-Z, for his 43rd birthday.
