The Rolex Sea-Dweller (Ref. 16660), often called the “Triple Six,” is a pivotal model in the brand’s professional dive watch lineage. Crafted in 40 mm stainless steel, it carries the robust character of the Sea-Dweller line, complete with a black dial, luminous markers, and a unidirectional rotating bezel for safe timing underwater. The watch is fitted with the signature Oyster bracelet, ensuring both comfort and security during wear. Known for its tool-watch aesthetic, this model embodies Rolex’s commitment to professional-grade diving performance.

Introduced in the early 1980s, the 16660 was the first Sea-Dweller to feature a sapphire crystal and an improved Helium Escape Valve, raising its depth rating to an impressive 1,220 meters (4,000 ft). It also introduced the caliber 3035 movement with a quickset date function, making it both practical and technically advanced for its time. As a transitional model bridging vintage and modern Sea-Dwellers, the 16660 remains highly sought after among collectors, admired for its historical significance, durability, and timeless Rolex design.
