Rolex Sea-Dweller 16660 MK lV dial

Another beautiful Rolex Sea-Dweller 16660 „Triple Six“ from 1985 with SN: 8058xxx. As the successor of the famous and well known Sea Dweller 1665, often called as a transitional reference, his 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 watch: has a excellent Mark IV gloss Tritium dial with white gold indices, original Tritium hands have aged different to the luminous on the dial. Case and bracelet were recently detailed, case is still in very good fat condition and far away from overpolished, which can be seen on a Sea-Dweller how deep the HEV is still within the case. Has a 83160 bracelet and 592 endlinks in very good condition with moderate stretch.

Watch has been adjusted and received an Rolex original crystal and gaskets and has passed a pressure testing recently by my watchmaker and is waterproof according to it’s specification, even I do not recommend excessive diving sessions with a vintage watch and can not guarantee for waterproofness.

Running strong with no indication for service in the near future. Old crystal comes with the watch.
A perfect toolwatch for every day and ready to wear. Differential taxation §25A UStG.
