The Sea-Dweller 4000 was developed as a professional diving watch, built to withstand extreme depths and demanding conditions. Reference 16600 from around 2002 carries that purpose-built heritage, with its black unidirectional bezel, robust 40mm case, and Superlative Chronometer certification. It is a serious tool watch that has also become a respected collector's piece, and this example comes complete with its box and guarantee papers.

The black dial is set with applied indices with lume and carries a date aperture at 3 o'clock, with "Sea-Dweller 4000" and "Superlative Chronometer Officially Certified" text. The 40mm stainless steel case features a black unidirectional bezel, a screw-down crown, and a screw-down case back. It is presented on a stainless steel Rolex Oyster bracelet with a folding clasp and is accompanied by its box, guarantee document, and booklets. The dial appears clean, the bezel and case have very minor marks, and the watch is working.
