ROLEX DEEPSEA SEA-DWELLER D-BLUE, REF. 116660

The Rolex Deepsea Sea-Dweller debuted in 2008 and is still in production. The Deepsea replaced the Sea-Dweller reference 16600. The Deepsea features a larger 44mm case, ceramic bezel, and patented Ringlock System. The Deepsea is the largest Rolex offered for sale. This particular example is the Deepsea D-Blue and debuted in 2014. The main difference between this model and the regular Deepsea Sea-Dweller is the blue dial that goes from almost black, dark blue to a lighter blue at the top of the dial; representing the ocean as you get deeper the water gets darker.
