Rolex Sea-Dweller 16660

The Sea-Dweller "Ref. 16660" is a Rolex diver's watch that was produced for only 10 years, from 1978 to around 1988. This watch is a transitional design, with a matte-finished black dial with direct luminescent paint, a characteristic of the early years, and the "Rolex Oyster Original Gas Escape Valve" engraving on the back of the watch, which is seen on later units. This model is highly popular among Rolex collectors as a transitional model between "old school" and "modern" watches.
