A Rolex Sea-Dweller 16660, Triple Six from 1984 with SN: 851xxxx. 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 1570 of the previous Sea-Dweller.
This 16660 has a mint second generation glossy Tritium dial with white gold indices and light yellowish aged lume and colormatching hands. Case might have been polished the past, but is in very good fat condition with lots of substance and has slight signs of prior wear. The 83160 bracelet is also in very good condition with moderate stretch, 13 segments and divers extension, claspcode S6 from 1994. As always, watch has been checked and adjusted by my Rolex authorized watchmaker. Watch has also passed a 10 Bar pressure testing recently and is waterproof according to it’s specification, even I do not recommend exessive diving session with a vintage watch and can not guarantee for waterproofness.
Running strong with no indication for service in the near future. The perfect toolwatch for every day.
