There are very few people in the world like Jay-Z. The artist also known as Sean Carter has been a Hip Hop mainstay for 30 years and many people call him the GOAT, or greatest of all time.

While his rapping has always been top-notch, one of the biggest things that Jay-Z is known for is being ahead of the crowd when it comes to business acumen. Recently, the multi-billionaire invested five million USD in Hong Kong’s Wristcheck, a platform that buys and sells luxury watches.

Jay-Z has been photographed with some of the most expensive watches in history. He has a PATEK PHILIPPE Grandmaster Chime, a watch now worth six million USD. Another watch that Jay wore on tour was a Richard Mille Blueprint, valued at 5.5 million USD.

Austen Chu, head of Wristcheck, said of having the 24-time Grammy-winning artists on board, “The incredible ecosystem JAY-Z has built at Roc Nation perfectly aligns with what we are building here at Wristcheck – the watch world of tomorrow.”
