Rolex Sea-Dweller Reference 1665: A Legacy of Depth
The 1665 emerged as a direct response to the demands of professional saturation divers. Unlike its predecessor, the Submariner, the Sea-Dweller was engineered to withstand the extreme pressures encountered at significantly greater depths. This necessitated the incorporation of several key features that distinguished it from other Rolex dive watches and laid the groundwork for future Sea-Dweller models. The most significant innovation was the inclusion of the helium escape valve, a crucial component for divers working in saturation diving environments. This valve allowed the escape of helium gas that could build up inside the watch case during decompression, preventing potentially damaging pressure imbalances.
The introduction of the helium escape valve was a game-changer. Before its implementation, divers often risked damaging their watches during decompression, as the trapped helium could cause the crystal to pop out or even crack the case. The 1665's helium escape valve, located at 9 o'clock, effectively addressed this problem, ensuring the watch's integrity even under the most extreme conditions. This feature, combined with its robust construction and superior water resistance, made the 1665 the preferred choice for many professional divers.

The movement powering the 1665 is a testament to Rolex's commitment to precision and reliability. The caliber 1575, an automatic movement, provided accurate timekeeping even under challenging conditions. Its robust construction ensured its resilience to shocks and vibrations, making it a dependable companion for divers undertaking demanding underwater missions. The movement’s accuracy and longevity are two of the reasons why the 1665 remains highly valued today.
