Reference:5514
Submariner → 5514
The 5514 is the COMEX Submariner, supplied exclusively to a single commercial-diving client and never offered at retail. COMEX (Compagnie Maritime d'Expertises) was a Marseille saturation-diving firm that supplied divers to the offshore oil industry from the 1960s onward. From 1970, Rolex delivered the 5514 to COMEX with the caseback engraved with COMEX markings and individual diver numbers, and the watches went out as working tools rather than catalog product.

Where it sits in the line
The 5514 is a 5513 case modified with a helium escape valve (HEV) for saturation diving, produced outside the retail ladder for a single institutional client.
It should not be confused with the 5517 MilSub. Both are non-retail branches of the 5513 era, but the 5517 went to the Royal Navy and the 5514 went to commercial divers working the offshore oil and gas industry at depths well beyond ordinary sport or military diving.
The 5514 also marks the point at which Rolex first factory-fitted the saturation-diving fix that would define the Sea-Dweller. COMEX went on to be a central partner in Sea-Dweller development, and the 5514 is where the requirement was established and the HEV was first grafted onto a no-date Submariner case.
Production outline
The 5514 was produced for COMEX with no parallel retail distribution. The supply relationship began in 1970, and the watches were issued to working divers with the caseback factory-engraved by Rolex.
COMEX-issue examples
Standard 5514 examples carry factory-engraved COMEX casebacks with individual diver identification numbers. A 1976 example documented in the dealer literature shows the configuration cleanly: a straight Rolex COMEX caseback engraved 1972, original COMEX diver owner, stated box, and Rolex service papers. That degree of paperwork is what the 5514 market expects from a top example.
In 1977, 16 examples of the 5514 were issued to Argentine Naval divers training at the COMEX facility in Marseille. ARA stands for Armada de la Republica Argentina. The watches were supplied as working tools for the Argentine Navy's professional diving program, run through COMEX, and the small confirmed total places the variant among the rarest pieces in the entire Submariner line.
The visual distinction is on the caseback. ARA examples carry "ARA" in the same position and block-letter format as "COMEX" on standard examples, replacing the COMEX text rather than supplementing it. No individual diver number appears in the COMEX format; any number that does appear follows Argentine Navy rather than COMEX convention.
The count of 16 is well established in collector and dealer literature but has not been verified against Argentine Navy procurement records, so it should be read as collector consensus rather than confirmed factory figure. Provenance of all 16 is actively tracked. An "ARA" 5514 surfacing without a documented chain of custody to one of the known examples should be treated with extreme caution; there is no legitimate route to additional supply, and the combination of scarcity and value makes this one of the highest-risk authentication scenarios in the vintage Submariner market.
Movement notes
The 5514 uses caliber 1520, the expected movement given the production period and the 5513 base. The 1520 is the long-run non-chronometer caliber that powers the 5513 through most of its run. The 5514's distinction is structural rather than mechanical: the HEV sits in the case, not the movement.
Dial map
COMEX dial
The standard 5514 dial carries COMEX branding in addition to the Rolex and Submariner text. The layout follows the 5513 format of the production period. Mid-to-late 1970s examples carry matte dials consistent with the 5513 Maxi or pre-Maxi era.
Cream and white dial variants
Some 5514 examples carry cream or white dials rather than the standard matte black. These lighter-dial variants are a distinct configuration within the COMEX issue; consistency of dial colour was not a procurement priority.
ARA dial
The 16 ARA-issue examples carry Argentine Navy markings on the dial in addition to the COMEX specification. They are distinct from both the standard COMEX dial and the standard 5513 dial, and they represent the rarest dial variant in the 5514 family.
Case, bezel, crystal, and crown
Helium escape valve — technical context
The HEV is the defining structural feature. COMEX divers operated in saturation environments, living for days or weeks in hyperbaric chambers and submersibles pressurised with trimix (a helium, nitrogen, and oxygen blend) and related specialised gas mixtures suited to extreme depths. At saturation pressures, helium molecules are small enough to permeate gaskets and seals and slowly accumulate inside the watch case. Without a release mechanism, the pressure differential during decompression can build up enough force to blow the crystal clean off.
The HEV on the 5514 is a Rolex-designed external valve positioned at nine o'clock on the case side, the brand's own answer to the saturation problem rather than a Doxa or ETA design. The valve is spring-loaded to stay sealed under ambient pressure and opens to vent when internal case pressure exceeds external pressure during ascent. A 5514 with a non-functioning HEV would be dangerous in actual deep-saturation use, which is why COMEX specified the 5514 rather than the retail 5513.
The rest of the case follows the 5513 specification, with the 40mm crown-guard case, acrylic crystal, and rotating dive bezel left untouched. The HEV is an addition to the 5513 architecture rather than a redesign of it.
Caseback engraving — authentication detail
Correct 5514 casebacks are engraved by Rolex at the factory, not by COMEX in the field. The format is the word COMEX in block letters followed by an individual diver number, for example "COMEX 7" or "COMEX 47." The number is not sequential production numbering; it corresponds to the diver's position on COMEX's diving team roster.
The engraving appears on the outside of the caseback, typically below the standard Rolex reference number. It is deep, clean, and executed to Rolex precision standards, never scratched, punched, or added in the field. The depth and consistency of the letter strokes are a primary authentication checkpoint.
Collector and academic research has cross-referenced many COMEX diver names against their watch numbers. A 5514 whose diver number can be matched to known COMEX personnel carries a significant premium over an undocumented example, and a named diver moves the watch from anonymous tool to documented service piece.
One specific provenance document recurs in the collector literature: the Henry Huet (HH) letter. Huet was a senior figure in COMEX's diving operations, and a letter from him accompanying a watch ties it to a specific period of COMEX service. An HH letter is one of the strongest provenance documents available for a 5514.
A shallow, inconsistent, poorly spaced, or badly positioned engraving is a major fraud signal. Given the prices these watches command, aftermarket engraving modification is a known fraud vector. Hand-scratched or punch-style text belongs on a suspect watch, not a real one.
Bracelets, end links, clasps, and packaging notes
COMEX-issued 5514 examples were delivered either on rubber (neoprene) dive straps or on standard Oyster-compatible metal bracelets, depending on diver preference and operational context at the time of issue. The rubber strap was the operational standard for actual diving (neoprene over neoprene suits, secure and minimal), while bracelets were common for surface and shore wear. No single delivery configuration can be called the definitive factory-issue standard; both rubber and Oyster configurations are period-legitimate, and either is correct on an otherwise-documented 5514.
As a modified 5513, bracelet fitment follows the 5513 pattern for the period. The 93150 solid-link Oyster with 580 end links is the expected late-production configuration for bracelet examples. COMEX procurement governed delivery rather than Rolex retail policy, which is why the range of strap configurations is wider than on a comparable retail reference.
Special branches
The 16 ARA-engraved examples issued in 1977 combine COMEX diving specification, Argentine Navy provenance, and a confirmed run of just 16 pieces. The caseback carries "ARA" in Rolex block-letter format in place of "COMEX." See the ARA discussion under Production outline for the authentication picture in full.
COMEX diver provenance
Even standard COMEX-issue 5514 examples gain significant value from documented diver provenance. A 5514 with a named original diver, matching caseback engraving, and a service history sits well above an undocumented example in the market, and the engraving can in some cases be cross-checked against COMEX personnel records.
Historical market and auction record
The 5514 market runs on provenance rather than volume. The reference was never produced for catalog distribution, so the auction record is thin and every transaction depends on the quality of the documentation, the condition of the caseback engraving, and the originality of the case and dial.
A strong documented example offered by Watches of Distinction carried a 1972-engraved COMEX caseback with diver number, box, and Rolex service papers; that kind of complete chain is what the 5514 market rewards.
Tim Vaux's Hodinkee report on Mike Wood's For Exhibition Only show records a private 5514 in collector hands and provides public-facing context for the Rolex-COMEX programme. Rolex Forum research has documented a $50,000 auction result for a 5514 carrying both COMEX and military connections, the kind of dual-provenance framing that concentrates two of the strongest value drivers in vintage Submariner collecting onto a single watch. The ARA variant carries that same dual character by definition: Argentine Navy divers trained at the COMEX facility in Marseille, so the watches are simultaneously military-issued and COMEX-connected.
