Rolex Sea-Dweller 16660 “Triple Six” 1988

Reference 16660 is a cult favorite among collectors

Affectionately known as the “Triple Six” among collectors due to its reference number, the Rolex Sea-Dweller 16660 is what we call a transitional reference. Rolex first introduced the Sea-Dweller ref. 16660 in 1978 as the second reference to join the saturation diving watch collection. It was the bridge between the vintage Sea-Dweller 1665 that came before it and the succeeding Sea-Dweller 16600, featuring design details from both generations. With that in mind, it’s important to note that Rolex produced both the Sea-Dweller 1665 and Sea-Dweller 16660 simultaneously for about five years.
