The Rolex Sea-Dweller reference 1665 is a significant model within the brand's professional tool watch lineage, distinguished by its enhanced water resistance compared to contemporary Submariner models. This reference was developed to meet the demands of professional saturation divers, featuring a helium escape valve (HEV) integrated into the case side, a key differentiator from other Rolex dive watches of its era. It represents a period of innovation in deep-sea horology, offering a robust solution for extreme underwater environments.

This reference features a 40 mm stainless steel case, designed for durability and resistance to high pressures. It is powered by the automatic Caliber 1575, a chronometer-certified movement known for its reliability and precision, offering a power reserve of approximately 42 to 48 hours. The watch is fitted with an acrylic crystal, contributing to its water resistance rating of 610 meters, and typically features a black dial with luminous hour markers.

For collectors, the reference 1665 is notable for its functional design and its place in the evolution of professional dive watches. Early examples, often referred to as "Double Red Sea-Dweller" (DRSD) due to two lines of red text on the dial, are particularly sought after. Later versions feature all-white text. The presence of the helium escape valve and its robust construction make it a distinct and historically important piece for those interested in the development of specialized timekeeping instruments.

The Rolex Submariner reference 5513 is a notable example within the Submariner line, distinguished by its two-line dial and lack of a date complication. Produced for an extended period, it represents a core offering for collectors seeking a straightforward and robust tool watch. Its design emphasizes legibility and functionality, aligning with the original purpose of the Submariner series. This reference is recognized for its consistent aesthetic throughout its production run, with subtle variations in dial text and bezel inserts.

The watch features a 40mm stainless steel Oyster case, offering durability and water resistance suitable for its intended use. Powering the reference 5513 is the automatic Caliber 1520 movement, known for its reliability. The crystal is acrylic, contributing to the vintage character of the watch. The unidirectional rotating bezel, typically with an aluminum insert, allows for elapsed time measurement.

For collectors, the reference 5513 is a significant model due to its long production history and the various dial iterations, such as gilt and matte dials, which present distinct collecting opportunities. Its appeal lies in its foundational design and its position as a non-date Submariner, making it a desirable piece for those who appreciate the model's original form. The watch is often paired with an Oyster bracelet, completing its functional aesthetic.

The Rolex Submariner reference 5517 is a rare and specialized variant of the Submariner line, distinguished by its unique dial and bezel configurations. This reference was not a standard production model available to the general public, setting it apart from other Submariner references of its era. Its specific characteristics cater to a particular collecting niche interested in purpose-built timepieces. The 5517 is often associated with a very limited distribution, contributing to its scarcity and distinct identity within the broader Submariner family. It represents a specific chapter in the development of Rolex's professional tool watches.

This reference typically features a stainless steel case, consistent with the robust construction of the Submariner series. The movement is an automatic mechanical caliber, designed for reliability and accuracy. The crystal is made of Plexiglas, a common material for Rolex watches from this period, providing durability and a classic aesthetic. The case dimensions are characteristic of vintage Submariners, offering a balanced presence on the wrist. The watch was engineered for water resistance, a fundamental attribute of the Submariner model.

For collectors, the 5517 holds significant appeal due to its extreme rarity and specific design elements, which differentiate it from more common Submariner references like the 5513. Its limited availability and specialized nature make it a highly sought-after piece for those focusing on unique and historically significant Rolex variants. The distinct dial markings and bezel insert are key identifiers for this reference, making it a focal point for advanced collectors seeking to complete comprehensive Submariner collections. Its place in the lineage of Rolex tool watches is defined by its specific, non-commercial origins.
