One of the most underestimated Rolex diver watches, a beautiful Rolex Sea-Dweller 16660, Triple Six from 1983/1984 with SN: 8054xxx. I swapped that watch some weeks ago with a fellow dealer but now bought it back, as it is one of the best 16660 I ever had – plus it fits perfect to my portfolio.
As the successor of the famous and well known Sea Dweller 1665, often called as a transitional reference, this was the first Rolex divers watch to have a sapphire crystal installed and offers a diving depth rating of 4000ft. As a tool watch for deep sea divers, this was obviously a practical and impressive feature. The improved water depth rating was thanks in part to a larger helium escape valve (HEV). Also having the new movement Caliber 3035 installed, which replaced the Caliber 1575 of the previous Sea-Dweller. I do really have a crush on this reference.
Coming to the watch itself: has a flawless Mark I matte dial, with all lume Plots fully intact and color matching hands, please see the detailed photography. Outer side’s caseback still has black paint on the engravings, this watch has been worn with care. Case appears to be polished once in the past, but is still in very good fat condition, with slight signs of use and hasn’t been polished during recent Rolex Service. Comes with a 83160 bracelet and 592 endlinks in very good condition with moderate stretch.
Watch comes with it’s original dedicated box with 16660 sticker on, calendar 82/83, Rolex manual and Rolex service guarantee, dated February 2019, so a Rolex service guarantee till February 2021.
Verdict: An amazing watch with mitMark I dial, one of the best 16660 I’ve seen so far, as an almost full set with it’s original box, amual and recent Rolex service . Differential taxation §25A UStG.
