Complete with Rolex box, punched certificate, 2016 Rolex service warranty, dive table and extension link... The tritium lume plots, hands and bezel pearl on this rare "Triple six" Sea-Dweller have naturally aged over the last 35 years to a beautiful warm cream colour. Fortunately for us, the previous owner made sure that Rolex didn't change or replace any of these important parts during a routine service with them in 2016. Manufactured in 1984 (retailed in Switzerland in 86) this transitional ref. 16660 was the first SD to feature a sapphire crystal glass, and our 8,2m serial number Mk III model was produced with the black gloss dial with white gold "Bicchierini" surrounds. Waterproof to 4000ft.
