Floyd Mayweather Jr. has no problem with showing off his purchased. In fact, he's personally shown us his cars, watches and gave us a tour of his mansion. Mayweather is also prone to displaying his luxury goods on his Instagram. Recently, he took the chance to stunt on the world with his one-of-a-kind Jacob & Co. The Billionaire watch. Jacob & Co. has this to say about the watch: "Created as a unique piece, The Billionaire truly epitomizes the brand’s passion for breaking boundaries. As the tourbillon caliber brings dynamism to its bejeweled enclosure, or the ballet of light of 260 carats of diamonds illuminates its exquisitely revealed heartbeat. The Billionaire is a dazzling representation of the courageous and rebellious Jacob & Co. spirit." https://www.instagram.com/p/BkiDdW-g0oi/?utm_source=ig_embed Why does it have such a confident name? Because it's worth $18 million and you'll probably only see billionaires wearing it. This watch comes with 260 carats of diamonds, a tourbillon mechanical movement and an 18k white gold case. https://youtu.be/F6f5wZHL7EI
