Sea-Dweller | 'Great White'
The Rolex Sea-DwellerThe Sea-Dweller was first developed to fulfil a narrow mission statement: survive the harsh deep-sea conditions of saturations divers. In the late 1960s, oil and gas exploration moved offshore, creating a new need for divers to go deeper than ever before and spend extended periods of time underwater, welding pipelines or installing underwater communications cables for hours at a time. The United States navy experimented with underwater habitats to prove the viability of saturation diving during SEALAB.
During SEALAB I and II, the divers were issued Rolex Submariners, however during decompression, the helium used in the breathing gas mixture would brutally expel the plexiglass on the watch as the helium forced its way out. As a response, Rolex developed a new watch featuring a helium escape valve on the side of the case (Swiss patent CH492246). It also delivered a greater depth rating, improving it from 200 to 610 meters. To be used by deep-sea divers, Rolex aptly named the model the Sea-Dweller. It was subsequently used by the U.S. Navy during the SEALAB III experiments, by the mythologised COMEX divers, and by many other professional divers since.
The 'Great White'This particular example of the Sea-Dweller ref. 1665 follows the ten-year production of the Double Red Sea-Dweller ref. 1665, from 1967 to 1977. Keeping the same reference number, it introduced a range of new features produced for a short period of 5 years, with the current example having been manufactured in 1979. The most notable difference was the replacing of red text on the dial with white writing, hence the nickname ‘Great White’, bestowed upon it by collectors. The ‘SUBMARINER 2000’ writing on the dial was also removed, clearly indicating that the Sea-Dweller would exist as its own model, rather than as a modified Submariner.
Further, the newer ref. 1665 features a modified engraving on the caseback, which is curved along the periphery, as opposed to engraved straight across. It was also the last variation of the Sea-Dweller to feature a plexiglass crystal, a feature considered by many as crucial component of a vintage watch.
The DesignThis particular Sea-Dweller ref. 1665 features a MK3 matte dial, identified tellingly by the position of the "R" in the word "Superlative", among other features. The dial is in excellent condition with creamy lume and matching original hands; the warmth of the patina complements the crisp black and white dial.
The original fat-font bezel has also aged gracefully, despite missing its luminous dot at 12 o'clock. It is worth noting that the bezel is demonstrably taller than on Submariner’s from the same period, providing more grip when handled under water. The case of the watch retains sharp, thick lugs and strong definition throughout, appearing unpolished.
Inside the Rolex Sea-Dweller 1665 sits the 26-jewel automatic 1570 caliber, which runs at 19,800 BPH and is chronometer certified. As per usual, the movement is controlled via a triple-lock crown.
