ROLEX SEA-DWELLER 16600
”What is that round thing on the side of the case” is a question we get every now and then when a Sea-Dweller (SD) is on the table or on the wrist. Explained in a nutshell; When deep-sea divers would go into a decompression chamber after long hours of doing their job deep below sea-level, Helium gas would build up inside the watch-case. The rising pressure caused by the Helium inside the watch would eventually be released by breaking or popping of the plexiglass crystal. After changing the case design (in collaboration with COMEX and in consultation with it’s divers) Rolex fitted the Helium Escape Valve to the SD and it performed flawlessly! All Crystals remained on the watch and intact and no other damage ever occurred again inside a decompression chamber. Ever since, the SD is easy recognizable amongst other features, by it’s round Helium escape valve on the left side of the case.
The Z-serial SD we are offering here is in a near mint condition and accompanied by the outer white cardboard sleeve, the inner and outer Rolex watch boxes, filled out and stamped warranty, Rolex hangtag, SD hangtag with serial number, Rolex booklets, extra SD Oyster link, the green SD folder with extra diving extension, SD tool, Buehlmann dive table and Rolex cleaning cloth. The entire watch is perfect and razor sharp, including the bezel and bracelet.
