Rolex Sea-Dweller 16660 Box

A Rolex Sea-Dweller 16660, Triple Six from 1985 with SN: 8668xxx. 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 gloss dial with white gold indices, nicely creme aged lume. Dial is starting slowly to change to matte throughout the dial, which is hard to see in the pictures. Cover laquer of the dial is changing, creating a numerous little „crates“ that appear matter, than the glossy parts. I’ve tried to highlight this in the pictures. Case was polished in the past, but is still in very good fat condition, with slight sign of use, has a 83160 bracelet and 592 endlinks in very good condition with moderate stretch.

Rolex box 68.00.08 and cover carton comes with the watch, but no papers. Watch has passed a pressure testing recently by my watchmaker 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. I perfect toolwatch for every day and ready to wear. Differential taxation §25A UStG.
