The Rolex Sea-Dweller, a watch synonymous with professional diving and enduring style, holds a special place in the hearts of collectors. Within the Sea-Dweller lineage, however, one model reigns supreme in terms of desirability and collectibility: the Double Red Sea-Dweller, or DRSD. This article will explore the fascinating history, characteristics, and enduring appeal of the Rolex 1665 Double Red Sea-Dweller, delving into its nuances, referencing specific examples, and offering insights into the market for these highly sought-after timepieces. We'll also touch upon related models, such as the Submariner 1680, which shares a certain kinship with the DRSD in its history and appeal to collectors.
The Genesis of the Double Red:
The Rolex 1665 Sea-Dweller, introduced in the late 1960s, represented a significant evolution in diving watch technology. Built to withstand the extreme pressures of deep-sea diving, it featured a helium escape valve, a crucial element for saturation divers. But it was the dial that would ultimately define a specific variant and cement its place in horological legend. Early examples of the 1665 featured a single red "Sea-Dweller" line on the dial. However, a subsequent iteration, produced for a relatively short period, featured *two* lines of red text: "SEA-DWELLER" above "SUBMARINER 2000ft = 600m". This seemingly minor change transformed the watch into the highly prized Double Red Sea-Dweller.
The exact production run of the 1665 DRSD remains a subject of debate among collectors, adding to its mystique. The limited production period, combined with the inherent durability and desirability of the Sea-Dweller, ensured that finding a well-preserved example today is a considerable challenge. This scarcity, coupled with the watch's inherent historical significance, has propelled the DRSD to iconic status within the world of vintage Rolex.
Distinguishing Features of the 1665 DRSD:
Several key characteristics distinguish the 1665 DRSD from other Sea-Dweller models and indeed from other Rolex watches. These include:
* The Double Red Dial: The defining feature, of course, is the double line of red text on the dial. The vibrant red against the matte black background is instantly recognizable and highly sought after. The exact shade of red and the font used can vary slightly between examples, adding another layer of complexity for collectors.
* The Helium Escape Valve: Located at 9 o'clock on the case, the helium escape valve is a critical functional element for professional divers. This valve allows helium gas to escape during decompression, preventing damage to the watch movement.
* The Case and Bracelet: The 1665 DRSD typically features a robust stainless steel case and a matching Oyster bracelet. The condition of the case and bracelet is crucial in determining the value of a particular example. Signs of wear, particularly on the case and bezel, are common but can detract from the value.
* The Movement: The 1665 DRSD housed the Rolex calibre 1575, a reliable and robust movement known for its accuracy and longevity. The condition of the movement is a crucial factor in determining the overall value and desirability of the watch.
