Bill embarks on a fascinating exploration of two seemingly identical Rolex 5513 Submariners, revealing subtle yet significant differences that distinguish a rare early Comex model. This detailed comparison highlights the nuances of vintage Rolex collecting, focusing on dial characteristics, lume plots, and the presence of a helium escape valve.
This will be a fun exploration.
In this first picture you will two watches which appear to be very similar. The Rolex coronet is almost identical very close to the Bart Simpson. The flat bottom is distinct. The Swiss t<25 also fills the space right to the edge between the minute marker. However the ft are not the same alignment.


By now I am sure you are a little curious. Big deal. A little examination and we see the lume plots are different. One appears to be about a 1mm closer to the minute markers and a little larger.



Your interest is still high.
The revealing shot.

The helium escape valve.
Now you can see what you have, the early Comex 5513.


Another piece on interesting Rolex info. These early Comex still did not have the Comex marking on the dial. It has all of the other characteristics with the serial engraved inside the case back and the obvious helium escape valve. I am sure there will be some controversy as to whether no Comex on the dial meet the broad consensus but this is what I have observed. This was an encounter with a friends watch.
Enjoy

About the Rolex Ref. 5514
The Rolex Submariner reference 5514 is a specialized variant of the Submariner line, produced exclusively for COMEX (Compagnie Maritime d'Expertises), a French industrial deep-sea diving company. This reference is distinguished by its unique helium escape valve, integrated into the left side of the case, a feature not found on standard Submariner models of its era. It represents a purpose-built tool watch designed for professional saturation divers, setting it apart from other Submariner references intended for broader commercial release. Its limited production and specific client make it a notable piece within the brand's history of professional watches.
The case of the reference 5514 is crafted from stainless steel, typically measuring 40mm in diameter. It houses an automatic movement, likely the Rolex Caliber 1520 or 1530, known for its robustness and reliability. The watch is fitted with a Plexiglas crystal, consistent with Rolex sports models from the mid-20th century, providing durability and ease of maintenance in demanding environments. The helium escape valve is a key technical modification, allowing accumulated helium to escape during decompression without damaging the watch crystal.
This reference appeals to collectors interested in specialized Rolex tool watches and those with a focus on professional diving equipment. Its association with COMEX and the presence of the helium escape valve make it a distinct and highly sought-after model. Variants often include dials with the COMEX logo, further emphasizing its unique provenance.

About the Rolex Ref. 5513Gilt
The Rolex Submariner reference 5513 Gilt is a notable variant within the long-running Submariner lineage, distinguished by its gilt dial printing. This reference was produced during a transitional period for the Submariner, bridging earlier iterations with later, more standardized designs. The gilt dial, characterized by its gold-colored text and minute track on a glossy black surface, represents a specific aesthetic that collectors often seek. It predates the matte dial era, offering a distinct visual signature that sets it apart from subsequent Submariner models. The presence of a plexiglass crystal is also a key characteristic, aligning with vintage Rolex production practices.
The case of the 5513 Gilt is typically crafted from stainless steel, maintaining the robust and functional design language of the Submariner series. It houses a self-winding mechanical movement, specifically the Rolex Caliber 1520 or 1530, known for its reliability and serviceability. The watch features a bidirectional rotating bezel, an essential tool for timing. The crystal is a domed plexiglass, contributing to its vintage profile and tactile feel. Water resistance was a core feature of the Submariner, designed for professional use.
This reference appeals to collectors interested in the early evolution of the Submariner and the specific characteristics of gilt dials. The production period, generally cited between 1963 and 1966, places it firmly in the vintage category, as defined by features such as the four-digit reference number and plexiglass crystal. Variants within the 5513 Gilt production can include subtle differences in dial text, lume plots, and bezel inserts, which are areas of particular interest for detailed study among enthusiasts. Its place in the Submariner history is significant as it represents a period of refinement before the introduction of later, higher-beat movements and different dial finishes.
