The Rolex Sea-Dweller, a watch synonymous with professional diving and enduring elegance, holds a special place in horological history. While the reference 1665 is most often associated with the coveted "Double Red" dial, a lesser-known sibling, the reference 1675, also boasts its own place in the pantheon of collectible Rolex divers. While not as instantly recognizable as the 1665, the 1675 offers a unique blend of history, design, and rarity that makes it a highly sought-after piece among seasoned collectors. This article will explore the intricacies of the Rolex 1675, focusing on its historical context, design features, and its position within the broader landscape of vintage Rolex Sea-Dwellers. We'll also delve into the reasons behind its desirability and the challenges of acquiring an authentic example.
Understanding the Reference 1675: A Precursor to the 1665
Before diving into the specifics of the 1675, it's crucial to understand its relationship to the more famous 1665 Double Red Sea-Dweller. The 1665, with its iconic "Double Red" text on the dial, is widely recognized as the epitome of vintage Sea-Dweller desirability. However, the 1675 predates the 1665 and served as a crucial stepping stone in the evolution of Rolex's professional diving watches. It represents a transitional period, bridging the gap between earlier Submariner models and the highly specialized Sea-Dweller that would follow.
The 1675, produced from approximately 1961 to 1971, shares many design elements with its successor. It features a robust Oyster case, designed to withstand the pressures of deep-sea diving. The screw-down crown and caseback ensure water resistance, a critical feature for a professional diver's watch. However, key differences distinguish it from the 1665, particularly in its movement and dial configurations. While some 1675 models might feature elements similar to the Double Red (e.g., red text), the true "Double Red" designation is almost exclusively reserved for the 1665.
Rolex 1665 Sea-Dweller Review: A Comparative Perspective
A comparison with the Rolex 1665 is inevitable when discussing the 1675. The 1665, introduced later, benefited from advancements in Rolex's watchmaking technology. It incorporated a helium escape valve, a crucial feature for saturation divers working in deep-sea environments. This valve prevents the build-up of helium within the watch case during decompression, a potential hazard that could damage the watch. The 1675, lacking this vital component, was not designed for the extreme depths targeted by saturation diving.
The dial is another key differentiator. The 1665 Double Red Sea-Dweller is instantly recognizable for its striking red text, reading "SEA-DWELLER" and "SUBMARINER 200m = 660ft." This double red text is a hallmark of the model and a primary driver of its collectible value. While some 1675 models might feature red text, they generally don't exhibit the same bold double red configuration as the 1665. This subtle difference, however, significantly impacts the watch's market value.
