He rapped, “I should get a […] for words that unify/Black and brown youth to shoot through the sky/Blueprint on my wrist cost 2.5/Only thing that flips the script between you and I.”

According to GQ, the watch was customized by Jay-Z’s personal jeweler Alex Todd. The jeweler spent around 3,000 hours customizing a case for the watch, which Jay Z first wore to the recent NAACP Image Awards. Todd shared a photo of the watch on his Instagram (below).
