Rolex Deepsea 44 mm 116660-Dblue Steel Blue Rolex Deepsea 44 mm 116660-Dblue Steel Blue

The Rolex Deepsea reference 116660-Dblue is among the most technically ambitious and visually dramatic watches Rolex has ever produced. Built around the groundbreaking Ringlock System — a nitrogen-gas release valve, a domed sapphire crystal, and a high-strength steel ring that together resist crushing water pressure — the Deepsea is rated to depths exceeding 1,000 meters, far beyond the practical needs of virtually any diver on earth. Yet it is this engineering excess that gives the watch its legend and its appeal.

The 116660-Dblue variant wears the celebrated D-Blue dial, introduced to honor filmmaker and explorer James Cameron's record-breaking solo dive to the Mariana Trench in 2012. The dial graduates from an inky black at the twelve o'clock position to a rich, saturated blue at six o'clock, evoking the transition from the sunlit surface to the crushing darkness of the deep ocean. It is one of the few Rolex dials that doubles as visual storytelling, and it gives the reference an instantly recognizable identity on the wrist.

The 44mm Oystersteel case is substantial and purposeful, with a helium escape valve at the nine o'clock position and a Triplock winding crown engineered for maximum water resistance. The black ceramic bezel is virtually scratchproof and features the familiar sixty-minute graduated scale with a luminous platinum-coated index, ensuring legibility in low-visibility underwater environments. The Oyster bracelet provides a secure, comfortable fit and is finished to Rolex's exacting standards, blending brushed and polished links in a manner that suits both the water and dry land.

Powering the Deepsea is an automatic movement — Rolex's in-house self-winding caliber — known for its precision and reliability. Rolex movements are COSC-certified chronometers and then further certified to Rolex's own Superlative Chronometer standard, meaning they are tested to even tighter accuracy tolerances after casing. The result is a movement you can trust through years of demanding use without compromise.

On the wrist, the Deepsea 116660-Dblue commands immediate attention. At 44mm with a case height designed to contain the Ringlock System, it wears large and bold — this is not a watch for those who prefer understated minimalism. It is a statement piece equally at home on the deck of a research vessel, at a black-tie dinner, or simply as the centerpiece of a serious watch collection. Its crossover appeal between hardcore dive tool and luxury collector's trophy is genuinely rare in the market.
