Another beautiful and perfect Sea-Dweller Rolex 16660, Triple Six from 1983 with SN: 746xxxx and a mint MKl matte dial. 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. I do really have a crush on this reference.
This 16660 has a Mark I matte dial, with all lume plots fully intact and color matching hands, both Tritium, no damage or weakness on the dial, I would rate it perfect. Both aged in an even vanilla tone. Case has been polished once during recent Rolex Geneva service and is unworn since that time, with all service stickers still on. Has a perfect Geneva polish with super fat lugs and matte champhers. Comes with a 83160 bracelet and 592 endlinks, full 12 segments and double divers extension in good condition with resonable stretch, good for another decade to wear. Bracelet itself appears to be original with the watch, clasp is a later replacement with code R. It is not uncommon that these clasps break with the years. They will not be repaired, just replaced, nowadays only in exchange with the original part, that will by kept by Rolex.
Watch comes with Rolex Service pouch and Rolex Geneva service card – so no issues within the next 2 year thanks to the Rolex service guarantee. Rolex has changed the chrystal, gaskets, crown, date disk, HEV and flywheel during the service, priced around 1100€. Be assured that this watch runs perfectly within the COSC specification.
