The Rolex Sea-Dweller reference 1665, particularly the Double Red Sea-Dweller (DRSD), occupies a hallowed space in the pantheon of collectible watches. This iconic timepiece, a testament to Rolex's pioneering spirit and horological mastery, remains highly sought after by collectors and enthusiasts alike. Its robust construction, groundbreaking water resistance, and captivating history contribute to its legendary status, making even a fleeting glance at a genuine example a memorable experience. This article will delve into the intricacies of the Rolex Sea-Dweller 1665, focusing specifically on the coveted DRSD, exploring its evolution, key features, and the factors that elevate it to the realm of rare and highly valuable vintage Rolex models.
The Rolex Sea-Dweller's origins lie in the demands of professional divers. In the late 1960s, Rolex, already renowned for its Submariner, sought to create a watch capable of withstanding the extreme pressures encountered at significantly greater depths. The result was the Sea-Dweller, a watch designed for saturation diving – a technique involving prolonged periods spent underwater at high pressure. This necessitated a significantly higher level of water resistance than the Submariner could offer. The reference 1665, introduced in 1967, marked a crucial step in this evolution.
Rolex Sea-Dweller Reference 1665: A Detailed Examination
The reference 1665 is instantly recognizable by its distinctive features. The most significant, and the one that defines the coveted DRSD variant, is the text on the dial. Early examples, often referred to as "Mark I" (and sometimes "Patent Pending" due to the inclusion of that wording on the dial), boast a striking "Sea-Dweller" inscription in red, above the "SUBMARINER" text, also in red. This double red text is the defining characteristic of the DRSD and accounts for its immense desirability. Later versions, often termed "Mark II," feature a single red line above "SUBMARINER," with "Sea-Dweller" appearing in white.
Beyond the dial, other features contribute to the 1665's unique identity. The case, typically constructed from stainless steel, is noticeably larger and more robust than the Submariner's, reflecting its enhanced water resistance. The crown guards are more substantial, providing added protection to the screw-down crown, a vital component for maintaining water tightness at significant depths. The crystal, usually acrylic, is noticeably thicker than on many other Rolex models, further contributing to the overall resilience of the watch.
The movement within the 1665 is another significant aspect. Powered by a robust calibre 1520, this automatic movement provided the necessary accuracy and reliability expected from a professional diving instrument. The calibre 1520, a workhorse movement, proved its resilience in demanding conditions, ensuring the 1665's enduring reputation for dependability. The helium escape valve, a crucial feature for saturation diving, is subtly integrated into the case at 9 o'clock. This valve allows helium gas to escape during decompression, preventing the crystal from cracking under pressure.
