As part of the “Party Like a Royal” New Years Eve event at Atlantis Paradise Island in Nassau, Bahamas, Nelly made a surprise performance.

While this is certainly newsworthy in its own right, his choice of watch has the internet on fire with the specifications of the time piece.

His Patek Philippe Nautilus — reference 5719/10G — features 18-karat white gold case that houses a dial set with 255 stones, baguette diamond hour markers, and an 18-karat gold dial plate. Additionally, the piece’s bracelet shows off an additional 1,343 diamonds totaling 18.73 carats.

With the rounded octagonal shape of its bezel, the ingenious porthole construction of its case, and its horizontally embossed dial, the Nautilus has epitomized the elegant sports watch since 1976.

Right now, a watch similar to Nelly's, is retailing on Chrono 24 for $794,825.
