Rolex Sea-Dweller – Black Dial – 16660 – 1984

The Rolex Sea-Dweller 16660, affectionately known among collectors as the “Triple Six,” represents a pivotal moment in Rolex’s professional dive watch history. Introduced in the early 1980s, this model bridged the gap between vintage Sea-Dwellers and modern iterations, offering a perfect balance of heritage and innovation.

Crafted from stainless steel, the 40 mm Oyster case embodies the robustness and precision Rolex is known for, featuring a unidirectional rotating bezel and a sapphire crystal—a first for the Sea-Dweller line. The matte black dial, with its luminous hour markers and Mercedes hands, provides optimal legibility even in the darkest depths. Beneath the surface, the Caliber 3035 automatic movement delivers reliable performance with quickset date functionality and a 28,800 vph beat rate.

Engineered for extreme conditions, the 16660 was the first Sea-Dweller to achieve a depth rating of 4,000 feet (1,220 meters)—a testament to Rolex’s relentless pursuit of excellence. With its vintage patina, solid presence, and historical importance, this 1984 Sea-Dweller is more than a timepiece—it’s a symbol of Rolex’s mastery in professional watchmaking.
