Rihanna turned to jeweler Jacob Arabo of the American watch and jewelry brand Jacob & Co. to realize his unique idea: a black choker necklace with a sparkling diamond watch, according to the New York Times.

The watch is on the neck

The watch that Rihanna chose as a necklace is the Jacob & Co. Brilliant Flying Tourbillon 47 mm, retails for $670,000 .

The expensive accessory is decorated with 338 baguette-cut white diamonds, with a total weight of 30 carats on the dial, crown and 18K white gold case.

In addition, the watch also has many more diamonds attached to the rotating tourbillon cage.

With that many diamonds, it is clear that the watch is quite heavy, not a suitable choice to wear on the neck.

Therefore, the jeweler’s biggest challenge is to create a strap that is both beautiful, luxurious, and supports the watch, so that it does not break when Rihanna goes out on the street.
