What We Buy
Every Sea-Dweller, Every Era
Double Red Sea-Dweller — All Marks
REF. 1665 · c.1967–1977 · MARK I THROUGH MARK V
The most intensely collected vintage Rolex sport reference. Two lines of red printing on the dial — "Sea-Dweller" above and "Submariner 2000" below, with additional red text — distinguish the DRSD from all later examples. Produced across five marks between 1967 and approximately 1977, each with its own dial text arrangement, case generation, and relative rarity. The Mark I is the most rare and valuable; every mark commands its own specific market position. We know all five and offer accordingly.
COMEX Sea-Dweller
REFS. 1665 · 16660 · 16600 · COMEX-ENGRAVED EXAMPLES
Rolex supplied Sea-Dwellers directly to COMEX — Compagnie Maritime d'Expertises, the French underwater engineering company — for use by their professional saturation divers. COMEX examples are identified by engravings on the caseback and, on some references, by unique dial printing. They represent the purest expression of what the Sea-Dweller was built for: actual professional deep-sea work. COMEX examples are among the most significant and valuable Sea-Dweller variants across every generation.
Sea-Dweller — Single Red & Ref. 1665
REF. 1665 SINGLE RED · c.1977–1980
The transitional generation between the Double Red and the fully redesigned 16660 — the single-line red "Sea-Dweller" text replaces the double red printing. The Single Red is less rare than the DRSD but shares the same ref. 1665 case and is a legitimate vintage collector reference in its own right. Acrylic crystal; gas escape valve; the final 1665 generation before the sapphire-crystal era.
Sea-Dweller — Ref. 16660
REF. 16660 · 1978–1988 · "TRIPLE SIX"
The first Sea-Dweller with a sapphire crystal — a significant departure from the acrylic-crystal DRSD era. The 16660 introduced the modern Sea-Dweller case proportions and the 1,220m / 4,000ft depth rating. Cal. 3035 transitioning to Cal. 3135. Known by collectors as the "Triple Six." The 16660 is a transitional reference — it bridges the deeply vintage DRSD era and the more modern 16600 — and has a dedicated following among Sea-Dweller specialists.
Sea-Dweller — Ref. 16600
REF. 16600 · 1988–2008 · 20-YEAR PRODUCTION
The longest-running single Sea-Dweller reference — 20 years of essentially unchanged production with Cal. 3135. The 16600 is the backbone of the modern Sea-Dweller secondary market: abundant enough to be accessible but deep enough in history to have real collector appeal, especially in unpolished condition with correct service history. Box and papers on a 16600 are more common than on vintage references but still add meaningfully to value.
Sea-Dweller — Ref. 116600
REF. 116600 · 2014–2017 · 3-YEAR PRODUCTION
The shortest-production modern Sea-Dweller — only three years before replacement by the 50th anniversary 126600. The 116600 updated the reference with Cal. 3136 (Paraflex shock absorbers) and Ringlock System for enhanced water resistance. Its brief production window of approximately three years gives it scarcity relative to the 16600 or 126600, and the secondary market reflects this. An underrated modern Sea-Dweller in terms of collector attention.
Sea-Dweller 50th Anniversary — Ref. 126600
REF. 126600 · 2017–PRESENT · 43MM · RED "SEA-DWELLER" TEXT
Introduced at Baselworld 2017 to celebrate the Sea-Dweller's 50th anniversary, the 126600 returned red printing to the dial for the first time since the 1970s — a deliberate nod to the Double Red heritage. Also grew to 43mm and introduced a date complication (absent from prior Sea-Dwellers). Cal. 3235. The 126600 is current production; purchased at full secondary market rates. Box and papers materially affect offers.
Sea-Dweller Deepsea — Refs. 116660 & 126660
REFS. 116660 · 126660 · 2008–PRESENT · 44MM · 3,900M RATED
The extreme variant — a dramatically larger 44mm case with the Ringlock System for a 3,900m / 12,800ft depth rating. The 116660 (2008–2018) runs Cal. 3135; the current 126660 runs Cal. 3235. The D-Blue "James Cameron" dial commands a premium over black in both generations. The 126660 also comes in two-tone Oystersteel and yellow gold Rolesor — a significant expansion from the all-steel original. All Deepsea configurations purchased actively.
Sea-Dweller Deepsea Challenge — Ref. 136660
REF. 136660 · 2023–PRESENT · 50MM · 11,000M RATED · RLX TITANIUM
The most extreme production Rolex ever made — introduced in 2023 as a tribute to the experimental Deepsea Special that accompanied the Mariana Trench dive in 1960. The 136660 is 50mm, constructed from Rolex's proprietary RLX titanium, and rated to 11,000m / 36,090ft — deeper than the Challenger Deep. Cal. 3230. Available in black and D-Blue gradient dials. A landmark reference in both engineering and collecting terms.
Collector Terminology
Sea-Dweller Nicknames & Key Variants
The Sea-Dweller — particularly the DRSD — has one of the most precise and demanding collector vocabularies in all of vintage Rolex. Knowing your mark is the first step to understanding what your watch is worth.
DRSD
Double Red Sea-Dweller
Ref. 1665, c.1967–1977 · Mark I through Mark V
The nickname that defines the most collectible Sea-Dweller generation — referring to the two lines of red-printed text on the dial. The specific arrangement, font, and content of that red text changed across five marks over a decade of production, and each mark is individually identified and valued by the collector community. "DRSD" alone is not sufficient description — the mark is what matters.
MK I
DRSD Mark I
Ref. 1665, c.1967–1969 · Rarest DRSD
The first and rarest Double Red configuration — featuring "SEA-DWELLER" in the upper red line and "SUBMARINER 2000" in the lower red line, with "ROLEX OYSTER" in white above. The Mark I dial lacks the "Super Case" text present on some later marks and has specific font characteristics that distinguish it from all subsequent marks. Low production numbers and immediate collector desirability make the Mark I the apex DRSD.
MK II
DRSD Mark II
Ref. 1665, c.1969–1971
The Mark II introduced the "SUBMARINER 2000" lower text with updated font characteristics and a transitional dial layout. Cal. 1570 continues. The Mark II is less rare than the Mark I but still a highly significant vintage Sea-Dweller — the second most collectible DRSD mark. Case condition and dial originality are primary value drivers; an unpolished Mark II in original condition commands a substantial premium.
MK III
DRSD Mark III — "Gas Escape Valve" Text
Ref. 1665, c.1971–1973
The Mark III introduced printed text referencing the helium escape valve on the dial — adding another line of information to the already text-dense Double Red face. Cal. 1570. The addition of the gas escape valve text is the primary distinguishing feature from Mark II. Mark III examples span a wide range of lume compound aging and case wear that creates significant variation within the mark.
MK IV
DRSD Mark IV
Ref. 1665, c.1973–1976
The Mark IV updated to Cal. 1575 and shows dial text refinements from the Mark III. The most widely produced of the five DRSD marks — making it the most accessible entry point into the DRSD canon, while still being a genuinely rare and valuable vintage Rolex. An honest, unpolished Mark IV with original tritium lume is a benchmark Sea-Dweller acquisition and the configuration most frequently encountered by serious collectors.
MK V
DRSD Mark V — Final Double Red
Ref. 1665, c.1976–1977
The last Double Red configuration — transitional toward the Single Red era. The Mark V is identified by specific dial text refinements and Cal. 1575. Produced for approximately one year before the transition to single-line red text. As the final expression of the Double Red's decade-long run, the Mark V carries its own distinct collector appeal and premium over the more common Mark IV.
CX
COMEX Sea-Dweller
Refs. 1665 · 16660 · 16600 · Professional issue
Sea-Dwellers supplied directly to COMEX — the French saturation diving company — for professional underwater operations. COMEX examples carry caseback engravings identifying them as COMEX-issued watches, sometimes with diver identification numbers. Some COMEX examples on the 1665 also show unique dial printing. COMEX provenance is the single most significant premium driver on any Sea-Dweller reference — a confirmed COMEX example commands multiples of a standard example's value.
SR
Single Red
Ref. 1665, c.1977–1980
The transitional generation where "SEA-DWELLER" appears in a single line of red text — replacing the double red arrangement but retaining the ref. 1665 case and acrylic crystal. The Single Red is less intensely collected than the DRSD but commands genuine vintage premiums, particularly in unpolished condition. It is the final acrylic-crystal Sea-Dweller generation and the last of the original 1665 reference.
TS
Triple Six
Ref. 16660, 1978–1988
The collector nickname for the ref. 16660 — three sixes in the reference number. The Triple Six is the first sapphire-crystal Sea-Dweller and the first with 4,000ft / 1,220m depth rating. Its 10-year production window is relatively short, and its position as a transitional reference between the deeply vintage DRSD era and the modern 16600 gives it a distinct identity in the Sea-Dweller lineage. Original, unpolished Triple Six examples are harder to find than their production numbers suggest.
DS
D-Blue "James Cameron" Dial
Deepsea Refs. 116660 · 126660 · 136660
The Deepsea's signature dial — jet black at the top transitioning to deep blue at the bottom, referencing the ocean's gradient from surface to abyss. Named for filmmaker and deep-sea explorer James Cameron, who wore a Deepsea during his 2012 solo descent to the Challenger Deep. The D-Blue commands a consistent and meaningful premium over the standard black dial across every Deepsea generation — in Oystersteel, in Rolesor two-tone, and on the Deepsea Challenge. Always the more desirable configuration.
CHAL
Deepsea Challenge
Ref. 136660, 2023–present · 50mm · 11,000m
The most extreme production Rolex in history — introduced in 2023 as a direct tribute to the Deepsea Special prototype worn on the exterior of the bathyscaphe Trieste during its 1960 descent to the bottom of the Mariana Trench. The 136660 is 50mm, made from RLX titanium, and rated to 11,000m / 36,090ft — the full depth of the Challenger Deep. It represents the pinnacle of Rolex's aquatic engineering lineage and is a landmark reference in both functional and collecting terms.
50TH
50th Anniversary Red Text (126600)
Ref. 126600, 2017–present
The 2017 reintroduction of red dial text on the Sea-Dweller for the reference's 50th anniversary was a deliberate, celebrated callback to the Double Red heritage. The 126600's red "SEA-DWELLER" text is the first red printing on a production Sea-Dweller since the 1970s. Early 2017 production examples are sometimes called "50th anniversary" by collectors; the red text configuration distinguishes the 126600 from all Sea-Dwellers produced between 1977 and 2017.
HEV
Helium Escape Valve
All Sea-Dweller references
The Sea-Dweller's defining functional feature — absent on all Submariners — is the helium escape valve built into the case at the 9 o'clock position. During saturation diving decompression in pressurized chambers, helium molecules penetrate the watch case; without the valve, the crystal can blow off during decompression. The HEV is the reason the Sea-Dweller exists as a separate reference from the Submariner, and its presence is the clearest single indicator that a watch is a Sea-Dweller and not a modified Sub.
Configuration Guide
Cases, Dials & Key Details
Double Red Dial Text — What to Look For
The DRSD's two lines of red text are the primary identification feature — but the specific text, font weight, line spacing, and character details change across all five marks. Mark I is identifiable by the absence of "Super Case" text and specific font proportions. Subsequent marks add, remove, or reformat text elements. Identifying a DRSD mark from photographs requires knowing exactly what to look for; we assess every submitted DRSD carefully before confirming an offer.
Acrylic vs. Sapphire Crystal
The 1665 (all DRSD and Single Red variants) uses an acrylic crystal — the same material as the vintage Submariner and Explorer of the same era. Sapphire crystal arrived with the 16660 in 1978. On the DRSD, an original unscratched acrylic crystal adds to the watch's originality; a replaced acrylic is disclosed and affects value less significantly than on a dial-critical reference. The flat acrylic profile of the DRSD is visually distinctive from the domed sapphire of later generations.
Tritium Lume on Vintage Sea-Dwellers
All 1665-era Sea-Dwellers use tritium lume on hands and indices — aging from white to cream, warm yellow, or deep brown over decades. On the DRSD, original naturally aged lume is exactly what collectors want. The large lume plots of the Sea-Dweller — necessary for deep-water visibility — age in ways that are visually dramatic on the best examples. Replaced or retouched lume significantly reduces value; we assess lume originality on every DRSD evaluation.
Unpolished Case Condition
As with all vintage Rolex sport references, case condition on the DRSD is primary. An unpolished 1665 with sharp lug edges, original brushed flanks, and crisp case geometry commands a very significant premium over a polished example. The Sea-Dweller's case is more complex than the Submariner's — with the helium escape valve housing, the screw-down crown, and the broader mid-case — and original condition across all these elements is what serious buyers prioritize.
COMEX Caseback Engravings
COMEX examples are identified by engravings on the caseback — typically "COMEX" plus a diver reference number. Authentication of COMEX engravings is critical: the engravings must be original factory or COMEX-applied markings, not aftermarket additions. Engraving depth, font, and patina relative to the caseback metal are the primary authentication indicators. A confirmed original COMEX Sea-Dweller is among the most significant professional-issue Rolex tool watches ever made.
Calibre Progression
1665 Mark I–II: Cal. 1570. 1665 Mark III–V and Single Red: Cal. 1575. 16660: Cal. 3035 transitioning to Cal. 3135. 16600: Cal. 3135. 116600: Cal. 3136 (Paraflex). 126600: Cal. 3235 (70-hr power reserve, Chronergy). Deepsea 116660: Cal. 3135. Deepsea 126660: Cal. 3235. Deepsea Challenge 136660: Cal. 3230. Movement calibre is a key dating and authentication tool on all vintage references.
Depth Rating History
The 1665 (DRSD and Single Red) is rated 2,000ft / 610m — printed on the dial in the "SUBMARINER 2000" text. The 16660 introduced 4,000ft / 1,220m. The 16600 and 116600 maintain 4,000ft. The 126600 is rated 4,000ft / 1,220m with the updated 3235 movement. The Deepsea 116660 and 126660 are rated 12,800ft / 3,900m. The Deepsea Challenge 136660 pushes to an extraordinary 11,000m / 36,090ft — the full depth of the Challenger Deep and the deepest rating of any production Rolex ever made. The depth rating printed on the dial is also a primary dating tool for identifying early 1665 marks.
Oyster Bracelet Originality
Original matching Oyster bracelets on vintage Sea-Dwellers (reference 93150 on the DRSD era; 78360/93160 on the 16660; 93160 on the 16600) contribute materially to value. A full-length original bracelet with correct end links and appropriate stretch for the watch's age is increasingly rare on vintage Sea-Dwellers. Non-original, replaced, or heavily stretched bracelets reduce offers. We identify correct bracelet references for every Sea-Dweller generation and assess accordingly.
Ringlock System (Deepsea)
The Sea-Dweller Deepsea's extraordinary depth rating is achieved through the Ringlock System — a nitrogen-alloyed steel ring inside the case that resists the crushing pressure at extreme depths. This engineering makes the Deepsea's case significantly thicker and heavier than any other production Rolex. The Ringlock System is a fundamental authenticating structural feature of the Deepsea — any case without it is not a genuine Deepsea, regardless of dial markings.

The Glenn Bradford Difference
Nearly Four Decades & Serious Rarity Collectors
Glenn Bradford Fine Jewelry has been a trusted name in fine jewelry and watches for nearly 40 years, with deep roots in the Hamptons and New York. We have built expertise across the full spectrum of fine watchmaking — Rolex, Patek Philippe, Vacheron Constantin, A. Lange & Söhne, Jaeger-LeCoultre, and beyond — and we bring a genuine collector's perspective to every evaluation.
The Sea-Dweller is a reference built for the rarest kind of work — saturation diving at depths that destroy ordinary instruments — and the rarest Sea-Dwellers are among the most significant watches in the entire Rolex catalog. The Double Red Sea-Dweller, across its five marks, requires a level of identification precision that is simply not found at most dealers. We know the difference between a Mark I and a Mark II, how to read the dial text configuration that determines which mark a given 1665 represents, and why that determination can mean tens of thousands of dollars to the person selling. We know what COMEX engravings should look like, how to assess their originality, and what they do to value across every generation of Sea-Dweller.
If you are considering selling a Double Red Sea-Dweller — at any mark — we are the right buyers. Bring us your DRSD with clear photographs of the dial, case, caseback, and bracelet, and we will tell you exactly what mark it is and exactly what it is worth. We deal in rarity. We understand it, and we pay for it.
How It Works
A Simple, Discreet Process
01
Submit Your Watch
Use the form above or contact us directly. For any DRSD, close-up photographs of the dial in natural light — specifically the red text lines and any white text above them — are essential to mark identification. For COMEX examples, a clear photograph of the caseback engraving is the first requirement. For all Sea-Dwellers, a photo of the helium escape valve at 9 o'clock helps confirm authenticity.

Common Questions
Frequently Asked Questions
It matters enormously. The five marks of the DRSD are not interchangeable in value — the Mark I is materially more valuable than the Mark IV, and identifying which mark you own requires knowing exactly what to look for on the dial. The key distinguishing features are: the presence or absence of the chapter ring, the arrangement and content of the red text lines, the font weight and character details of specific words, and whether the gas escape valve is referenced on the dial. To identify your mark, we need clear close-up photographs of the dial in natural daylight — specifically the text. Submit through the form above and we will identify your mark and provide a preliminary offer based on it.
Yes. We work with clients throughout the United States and internationally. Submit your piece through the form above with clear photographs of the case, dial, caseback, and any paperwork.
