Rolex Sea-Dweller Reference 1665: A Deep Dive into History
The Rolex Sea-Dweller, introduced in 1967, was born from a collaboration with Comex, a French commercial diving company. Comex's demanding requirements for a watch capable of withstanding the extreme pressures of saturation diving pushed Rolex to create a timepiece far exceeding the capabilities of its existing Submariner. The result was the reference 1665, a watch engineered for unparalleled reliability and durability in the most challenging underwater environments. This model featured a helium escape valve, a crucial component for preventing crystal damage during decompression stops from saturation dives. This valve, positioned at 9 o'clock, is a hallmark of the Sea-Dweller lineage and a key distinguishing feature of the 1665.
The initial iterations of the 1665 featured single red text on the dial, reading simply "Sea-Dweller." However, it's the subsequent "Double Red" variant, produced for a short period in 1971 and 1972, that commands the highest prices and collector interest. This version boasts "Sea-Dweller" in red lettering above the "Submariner" text, also in red, creating the distinctive "Double Red" nomenclature. This seemingly minor detail transforms the watch into a highly sought-after collector's item.
The Allure of the Double Red: Distinguishing Features and Markings
The Rolex Sea-Dweller 1665 Double Red is instantly recognizable by several key features:
* Double Red Dial: The most obvious characteristic is the double line of red text, "Sea-Dweller" above "SUBMARINER," on the dial. This is what sets it apart from other 1665 variations.
* Markings and Variations: The Double Red is often categorized into "Mark I," "Mark II," and "Mark III" based on subtle dial variations such as the font style, the placement of the text, and the presence or absence of certain markings. These nuances are crucial for authentication and significantly impact the value.
* Helium Escape Valve: The presence of the helium escape valve at 9 o'clock is a defining feature of the Sea-Dweller line. Its inclusion reinforces the watch's professional diving heritage.
* Case and Bracelet: The 1665 typically features a 40mm stainless steel case and was initially offered with an Oyster bracelet, although variations exist. The bracelet is another crucial aspect for assessing authenticity and condition.
