Rolex implemented major changes to the Sea-Dweller starting in 1981. The sapphire crystal became standard starting with the Ref. 16660 and major developments were implemented into the model which included a uni-directional bezel as opposed to the bi-directional bezel found in previous examples, a larger and more reliable helium escape valve was added, and we see the introduction of the first solid end link (SEL) bracelets with the Ref. 93160 bracelets with attached 592 end links becoming standard around 1981-1982. The Sea-Dweller also received a new movement, the Cal. 3035 which allowed for Quick-Set date function.

In the early 1980's Rolex was working very closely with the Compagnie Maritime d' Expertise Company (COMEX) to develop a tool watch to accompany the company's divers who started to work at deeper depths as a result of increasing mixed gas diving standards of early 1980's and the Ref. 16660 is a perfect example of the two company's partnership to achieve a tool watch to meet specific needs.
