Produced for over 40 years, the Sea-Dweller was first designed for deep sea divers at COMEX, and as of 1967 was the first commercially available dive watch to have a helium escape valve. The reference 16600 was introduced to the market in 1978, and has a clean and contemporary look, clearly designed for a specific purpose. Often compared to Rolex's Submariner models, the most noticeable difference between the two models is the lack of magnified cyclops on the crystal above the date window on the Sea-Dweller. The depth rating is another difference - the Sea-Dweller is rated to 4000 feet, which is four times the depth rating of modern Submariners.
Designed for use by divers, the Sea-Dweller 16600 has become a popular choice for many as an every-day watch, as there is no worry about contact with water. With all of the history and innovation that comes with the Sea-Dweller line, the wearer can feel comfortable knowing that this watch is precise, durable, and water-resistant. Production of the Sea-Dweller ended in 2008, and was brought back in 2014 at Baselworld with the reference 116600.
The above watch appears unpolished and in extremely good condition, it is a one owner watch with a complete package. A great watch built like a tank.
