The Rolex 1665 Double Red Sea-Dweller (DRSD) is arguably one of the most sought-after and iconic dive watches ever produced. Its legendary status stems not only from its robust construction and unparalleled reliability, perfectly suited for professional diving, but also from its incredibly limited production run and the striking aesthetic of its "Double Red" dial. Finding a Rolex 1665 DRSD for sale is a rare opportunity, and understanding the nuances of the watch, its history, and the market is crucial for any prospective buyer. This article delves deep into the world of the 1665 DRSD, providing a comprehensive guide for those considering purchasing this highly collectible timepiece.
The Rolex Sea-Dweller Lineage: A History of Depth and Durability
Before examining the specifics of the 1665 DRSD, it's important to understand its place within the broader Rolex Sea-Dweller lineage. The Sea-Dweller emerged as a response to the increasing demands of professional saturation diving in the late 1960s. Unlike the Submariner, designed for recreational diving, the Sea-Dweller was engineered to withstand the extreme pressures of deep-sea exploration. This necessitated significant advancements in case construction, water resistance, and the use of helium escape valves (HEV) to prevent case implosions during decompression.
The first Sea-Dwellers, like the reference 1660, laid the foundation for future iterations. However, it was the reference 1665 that truly cemented the Sea-Dweller's place in horological history. Introduced in the early 1970s, the 1665 incorporated numerous improvements, including a larger case size and the introduction of the iconic helium escape valve. This valve, subtly positioned at 9 o'clock, allowed helium gas to escape during decompression, preventing damage to the watch's crystal and case.
The Double Red Sea-Dweller: A Collector's Grail
Within the already desirable 1665 family, the Double Red Sea-Dweller stands apart. The key distinguishing feature is, of course, the dial. Unlike later iterations of the Sea-Dweller, which featured a single red "Sea-Dweller" inscription under the Rolex crown, the 1665 DRSD boasts two lines of red text: "Sea-Dweller" sits above "200m = 660ft." This seemingly minor detail significantly impacts the watch's desirability and value. This unique red-on-red dial was short-lived, produced only for a brief period, making authentic examples extremely rare and highly sought after.
The reasons behind the relatively short production run of the Double Red dial are debated among collectors. Some suggest that Rolex altered the wording to improve legibility or to simplify the production process. Others speculate that market demand dictated the change. Regardless of the reason, the limited production run transformed the 1665 DRSD into a legendary piece of horological history.
