Notes: The 1660 is another reference number which was produced using two different movements. This example uses the 3035. Later examples use the 3135.

Often nicknamed the “Triple Six” and considered a transitional reference, this Sea-Dweller brought about many changes to Rolex’s extreme diver’s watch. When the original Deepsea arrived, with a waterproof rating of 12,800ft, it was something of an immediate opinion splitter, with many wondering just who exactly it was supposed to be for. What form of superhuman could possibly be in need of a watch constructed to survive a plunge more than three times deeper than the Sea-Dweller, a model that had always easily been a match for the rigorous world of commercial saturation diving?

The Rolex Sea-Dweller ref. 16660 Triple Six boasted plenty of changes. Firstly, its water resistance doubled to 4.000 feet (1,220 meters). As a tool watch positioned for deep sea divers, this was certainly a practical and impressive enhancement. The improved water depth rating was thanks in part to a larger helium escape valve (HEV). A quick refresh, the HEV is the Rolex-patented mechanism that allows watches to properly decompress when resurfacing. That is, the HEV automatically releases built up helium (and other gasses) from the watch. The releasing of the gasses essentially normalizes differences in internal and external pressure, thus preventing the crystal from bursting off or other damage to the watch.

The Rolex Sea Dweller is one of the most beloved sports watches made in history. Developed to both withstand the elements and be wearable in most settings, the Rolex Sea Dweller can be taken to depths of 1,220 meters or 4,000 feet - in the world most amazing seas. The Sea Dweller Rolex features automatic winding technology, ultra-smooth 31 jewel movement, Helium Escape Valve, deluxe sapphire crystal, waterproof case, and Quickset date. Depending on one´s taste, the Rolex Sea Dweller Deep Sea is available in a variety of models and bracelet types. Additionally, the used Rolex Sea Dweller price is dependent on the year the watch was made, feature set, and degree of rarity. Google Rolex Sea Dweller Review to learn more about the watch and customer feedback. Loyal Rolex Sea Dweller 16600 fans tend to wear them no matter where on the earth they roam and rave about how the watch inspires their adventurer within.
Mechanism:
The Rolex caliber 3035 was introduced in 1977 as what many refer to as a high-beat caliber 1575. In 1977, the Cal. 3035 ended the 12-year run of the 1570, it became the first men’s high-beat caliber Rolex had ever made. By increasing the balance speed from 19,800bph to 28,800bph, the new movement was able to offer an even greater level of accuracy and robustness than the already formidable abilities of its predecessor. The 3035 has a hacking capability.

It was this new speed on the 3035, causing the seconds hand to ‘tick’ eight times per second, that introduced the smooth sweep that is so characteristic of Rolex watches. Along with upping the movement’s frequency, which has since been adopted by every subsequent model Rolex has produced, the Cal. 3035 also led the field in another aspect; it was the first automatic caliber to feature a quickset function.
Family Notes: Since its production in 1967, the Rolex Oyster Perpetual Sea-Dweller has established itself as the world's most impressive dive watch. The Sea-Dweller can remain waterproof for up to 4,000 feet.
