This sought after Rolex Sea-Dweller has a black ceramic bezel with stainless steel case and band. It is circa 2015, with some light wear, but is in great condition overall. Developed for professional saturation diving and extended deep-sea missions, the Sea‑Dweller combines a number of technical innovations to guarantee enhanced waterproofness, robustness through and through, optimum legibility and comfort in all circumstances.
The helium escape valve, which is exclusive to Rolex and was patented in 1967, the year the Sea‑Dweller was launched, is an intrinsic feature of the model and a major invention for saturation diving. It is screwed to the case and consists of a hermetic cylinder, a piston, a gasket and a spring, acting as a safety valve in case of excess internal pressure.
It comes as an almost full set complete with box, card and string tag, however it is missing a few links (fits 18cm). The card holder does have a small rip in it.
This watch has been professionally serviced.
