Description

The Rolex Sea-Dweller 16660 Black, often nicknamed the “Triple Six,” represents a major evolution in Rolex’s professional dive watch lineup. Introduced in the early 1980s as the successor to the original Sea-Dweller 1665, this model was the first to feature a sapphire crystal, significantly improving scratch resistance and durability.

Housed in a robust 40mm stainless steel case, the watch is capable of withstanding depths of up to 1,220 meters (4,000 feet), thanks to its upgraded helium escape valve and thicker case construction. The sleek black dial—available in both matte and glossy variants during its production run—is paired with luminous hour markers and Mercedes-style hands for excellent underwater legibility.

Powered by the reliable Rolex Caliber 3035, the 16660 also introduced the quickset date function to the Sea-Dweller line. Its unidirectional rotating bezel, solid Oyster bracelet, and professional-grade build make it a tool watch of the highest order. With a production span from roughly 1978 to 1989, the Sea-Dweller 16660 is now considered a highly collectible vintage diver that bridges the gap between old-school charm and modern performance.
