The Genesis: 1967 – The First Sea-Dweller (Reference 1665)
The year 1967 marked the birth of the Rolex Sea-Dweller, a watch designed specifically for professional saturation divers. Initially, it boasted an impressive water resistance of 610 meters (2,000 feet), a significant leap forward in dive watch technology. The Reference 1665, often referred to as the "Double Red" due to the "Sea-Dweller" and "2000ft=610m" markings on its dial in red, quickly gained a cult following. Its robust construction, featuring a helium escape valve (first introduced in the experimental Submariner 5513 in the early 60s and subsequently adapted for the Sea-Dweller), addressed the issues of helium saturation encountered during deep-sea dives. This valve allowed helium gas, which permeates the watch case during prolonged saturation dives, to escape safely, preventing the crystal from shattering. The 1665 also featured a distinctive matte black dial, luminous markers, and a robust oyster case, hallmarks of Rolex reliability and durability. Finding a pristine example of the 1665 today is a significant undertaking, making it a highly sought-after collector's item. The price for a well-preserved 1665 can be substantial, making a "Rolex Sea-Dweller price guide" an invaluable resource for potential buyers.
Evolution and Enhancement: 1978 – The Reference 16660
The 1978 introduction of the Reference 16660 marked a considerable advancement in the Sea-Dweller's capabilities. Most notably, the water resistance was dramatically increased to an astounding 1,220 meters (4,000 feet). This significant jump reflected Rolex's unwavering commitment to pushing the boundaries of underwater exploration. The "Triple Six" (16660), as it's affectionately known, showcased a revised helium escape valve, refined case design, and a more legible dial. The red text on the dial was replaced with white, making it visually distinct from its predecessor. The 16660 established itself as a benchmark for professional dive watches, its robust build and enhanced depth rating making it a trusted companion for the most demanding underwater missions. Prices for the 16660 also reflect its historical significance and desirability.
