About the Rolex Sea-Dweller Deepsea 116660 Blue
The Rolex Sea-Dweller Deepsea 116660 was introduced in 2008 as the most extreme dive watch Rolex had ever produced, engineered to withstand pressures at extraordinary depths thanks to a reinforced Oyster case, a sapphire crystal of exceptional thickness, and the proprietary Ringlock System inside the case structure. The blue dial variant gained enormous cultural momentum when Rolex released it in 2014 as a tribute to filmmaker and explorer James Cameron, whose solo dive to the Challenger Deep in 2012 was accompanied by a Deepsea prototype, making the D-Blue dial a piece of horological storytelling as much as an instrument watch. At 44 mm in Oyster steel with a black ceramic-insert bezel, the 116660 is unmistakably purposeful in size and presence, and the graduated deep-blue-to-black dial evokes the ocean's descent from sunlit surface to lightless depth.
What to Look For
When shopping Rolex 116660 Blue examples, buyers should verify the exact dial designation, as the D-Blue configuration appears under slightly different reference suffixes such as DBL1 or Dblue but describes the same graduated blue-black dial on the same 44 mm steel case. Condition of the bezel insert, bracelet stretch on the Oyster bracelet, and the presence of original box and papers are the primary drivers of value within this reference, with unworn or lightly polished examples commanding a meaningful premium over heavily worn pieces.
Frequently Asked Questions
What does D-Blue mean on the Rolex 116660?
D-Blue refers to the distinctive graduated dial on the Rolex Sea-Dweller Deepsea 116660 that transitions from deep blue at the top to black at the bottom, evoking ocean depth. The designation honors James Cameron's 2012 dive to the Mariana Trench and was introduced by Rolex in 2014 as a special dial variant of the 116660 reference.
What is the case size and material of the Rolex 116660 Blue?
The Rolex 116660 is a 44 mm watch crafted in Oyster stainless steel, making it one of the largest and most robust sport watches in Rolex's lineup. The substantial diameter is paired with a thick sapphire crystal and a reinforced case construction that give the watch its extreme-duty dive watch character.
Is the Rolex 116660 Blue still in production?
The reference 116660 was discontinued by Rolex and succeeded by the updated Sea-Dweller Deepsea 126660, which means 116660 examples on the pre-owned market are now the only way to acquire this specific reference. That discontinuation has sustained strong collector and buyer interest, making authenticated 116660 D-Blue watches a sought-after find on the secondary market.
