With 239 emerald-cut baguette diamond stones totaling 260 carats and an 18k white gold case, it takes audacity and a lot of cash to feel the need to rock Jacob & Co.'s "Billionaire Watch." And, needless to say, these are qualities that fashion mogul, F1 enthusiast, and Italian businessman Flavio Briatore has in ample supply. Known for selling $1,000 jeans and $500 pairs of swim trunks, it should come as no surprise that Briatore would decide to partner with his psychological equals in the watch industry, Jacob & Co., to produce such a timepiece. Working together on the design, it's clear that extravagance, wealth, and luxury probably were top of mind throughout its development. The piece itself, the only one of its kind, combines a rectangular 47.5mm wide and 58mm tall case with a diamond coated bracelet, which also secures an exclusive Jacob & Co. mechanical movement and a manually-wound tourbillon reserve. In total, the watch is made up of only 167 parts, including its skeleton-like internal frame and diamond hour markers. Of course. In total, the price comes to 18,000,000 Swiss Francs. Clearly pocket change to a man like Briatore.
