Rolex Sea-Dweller 1665

Rolex Sea-Dweller 1665 Double Red Mk4

Debuting in 1967, with the specific aim of bolstering Rolex's dive watch offering, the Rolex Sea-Dweller was built upon the industry-leading dive watch credentials that the Submariner had earned Rolex over the previous 14 years. Created specifically with professional saturation divers in mind, Rolex collaborated with diving companies like COMEX to perfect the Sea-Dweller's design and ensure it would be the ultimate dive watch. Featuring the ingenious Helium-Escape Valve that Rolex had patented the same year, a hugely impressive water resistance, and a sizeable case design, the Sea-Dweller rightfully toppled the Submariner as Rolex's most hardcore dive watch. Today vended in a few separate styles such as two-tone, with various dials, and in two different case sizes (43mm and 44mm), the Sea-Dweller has taken a leaf from the rest of Rolex's offerings and merged its tool-watch focused design with tasteful aesthetics, to create one of the most sought-after and best-equipped dive watches that any diver might ever need. The 1665 Sea-Dweller was the first watch manufactured by Rolex to include the HEV. Made specifically with commercial divers in mind, it had a depth rating of 2000 feet, as opposed to the 660 feet of the standard Submariner. At first commercially introduced with the text "SEA-DWELLER SUBMARINER 2000" in red, like ours here, this iconic red text was eventually swapped for white inscriptions in 1977. Brand : Rolex Dimensions : 40mm Model : Sea-Dweller Movement : Automatic cal. 1570 Reference : 1665 Bracelet : Stainless steel Oyster bracelet Year : 1976 Condition : Excellent Material : Stainless steel Included : Watch only Dial Color : Black THE DIAL Featuring its iconic Mk4 double red dial, this example was amongst the last batch of double red Sea-Dwellers as the Mk4 dial was followed by the plain white inscription dial that also lost the "Submariner" distinction. Additionally, this example's hour markers and hands have aged to include a stunning yellow patina. THE CONSTRUCTION An imposing watch on account of its intended use as a tool watch for divers, the ref. 1665 is tall on the wrist thanks to its revolutionary HEV and domed crystal. Additionally, this example's uniquely aged bezel adds a wonderful level of visual depth to its aesthetic.
