Pre-Owned Rolex Sea-Dweller ref 16660 (1984) "Triple Six" was produced for a little over a decade between 1978 and 1989. It replaced the vintage ref. 1665, bringing with it a sapphire crystal, increased water resistance, and a higher-beat movement. Depending on the reference, it will also have either painted indices or modern white gold-trimmed indices. The example you see here is the latter. With the release of ref. 16660, the bezel was upgraded to a uni-directional mounting, and the Helium Escape Valve is larger. This Rolex is an integral part of the collection's history. You won't regret adding it to your watch box.
Excellent in every way. I think you’re busy setting the gold standard in this business.
Great pictures of the actual watch. Expedient delivery. 100% Authentic
