The Genesis of a Legend: Rolex Sea-Dweller References and the 1665
Before dissecting the Double Red, it's crucial to understand its position within the Rolex Sea-Dweller lineage. The Sea-Dweller emerged as a response to the growing demands of professional saturation diving. While the Submariner had already proven its mettle in underwater exploration, the burgeoning field required a watch capable of withstanding even greater depths and pressures. This need led to the development of the first Sea-Dweller, the reference 1665, a significant step forward in dive watch technology.
Several key features distinguished the 1665 from its Submariner counterpart. Most notably, the 1665 boasted a helium escape valve (HEV), a crucial innovation for saturation divers. This valve allowed helium gas, used in saturation diving chambers, to escape from the watch case during decompression, preventing the crystal from shattering under the immense pressure differential. The larger case size, compared to the Submariner, also contributed to its enhanced robustness and water resistance.
The evolution of the 1665 itself is fascinating. Early models featured a single red line of text on the dial, reading "SEA-DWELLER." However, it's the subsequent "Double Red" variant, with the additional "SEA-DWELLER" line in red above the existing one, that truly captured the imagination of collectors. This subtle yet significant change in dial markings transformed the watch into a highly desirable collector's item. The production run of the Double Red was relatively short, adding to its rarity and driving up its value.
