Another beautiful Rolex Sea-Dweller 16660, Triple Six from 1986 with SN: 9335xxx. 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 watch: has a second generation gloss dial with white gold indices and white lume. Dial surface is changing to matte gradually throughout the dial, which can easily be seen in the provided pictures under different lighting conditions. Cover laquer of the dial is changing, creating a numerous little „crates“ that appear matter, than the glossy parts turning it to a „stardust“ surface. Case appears to be unpolished with fat lugs and only minor signs of use. The 83160 bracelet with 592 endlinks in very good condition with moderate stretch, claspcode I5 (1984) making it the original bracelet of the watch. Has 11 segmets, divers extension, plus three segments in spare.
Has been fully serviced in 2015 through authorized Rolex workshop, receipt is enclosed. As always, watch has been reviewed and adjusted by my Rolex authorized watchmaker. He changed all gaskets and the sapphire crystal and it 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. Watch is running strong with no need for another service in the near future.
