This gleaming beauty is no ordinary wristwatch - the Jacob & Co "Billionaire" watch will make a dent in your pocket book the size of a small island. Valued at $20 million, the one-of-a-kind "Billionaire" is made of 18K white gold and 260 carats of diamonds, an unprecedented amount of bling. Unfortunately for all prospective buyers, this watch already belongs to one undisclosed high net worth individual.
