Reference:16610
Submariner → 16610
The 16610 is the standard Submariner of its era, the reference most people picture when they say “Submariner.” It entered production around 1988, replacing the 16800, and ran until 2010 when the ceramic-bezel 116610LN took over. That is about 23 years on a single reference number, and no other Submariner Date reference comes close: the 16800 ran about eight years, the 116610LN ran ten. The 16610 ran for more than two decades while the rest of Rolex sports production moved around it, and it absorbed a long list of small changes along the way that reward careful attention.
Across those 23 years, the 16610 accumulated a full generational history within a single reference number. Three lume technologies, two bracelet systems, and a sequence of anti-counterfeiting measures that mark out the late examples all passed through without the reference being renumbered. Caliber 3135 never changed.

Where it sits in the line
The 16610 follows the transitional 16800 and precedes the 116610LN. Where the 16800 introduced sapphire crystal and the 300m rating to the date Submariner, the 16610 settled the platform — caliber 3135, definitive Triplock crown, Oyster case, graduated 60-click aluminum bezel insert — and kept it there for over two decades. The broader public associates the 16610 with the Submariner Date because it was in production for so long, in such volume, and looked so consistent.
It ran alongside the no-date 14060 and 14060M. Together, these references represent the five-digit Submariner era. The 16610 is the date version; the 14060 / 14060M is the no-date version. Same case, same bracelet architecture, many of the same specification milestones.
The 16610 also spawned the 16610LV anniversary variant (the “Kermit,” covered in its own article) in 2003. The relationship matters: the 16610LV uses the identical case and movement, differing only in its green aluminum bezel insert and Maxi dial.
Timeline of changes through the 23-year run
The 16610’s long production splits into five loosely-bounded phases. The transition points are approximate and do not align with calendar decades.
Phase 1 — Early production: tritium dials, drilled lugs, stamped end links (~1988–late 1990s)
Serial range: pre-X through X series.
The earliest 16610 examples sit closest in character to the preceding 16800. Dials carry tritium lume, marked T SWISS T or T<25 near 6 o’clock; tritium has a 12.3-year half-life, so after 20 to 30 years the lume on these dials ranges from lightly patinated to heavily aged, with the cream, tan, or orange tones collectors call tropical. Drilled lug holes run through the case, allowing strap changes without tools. The bracelet is ref.93150 with stamped hollow 501B end links and a stamped Fliplock clasp with wetsuit extension. The rehaut stays smooth and unengraved throughout the phase.
This is the 16610 at its most vintage-adjacent; the early watch feels like an update of the specification that started with the 5513, not a departure from it.
Phase 2 — Luminova transition (~1998–2001)
Serial range: A to P series (roughly 1998 to 2000).
A brief window exists between the full tritium era and the settled Luminova era. Dials marked SWISS only — without the T prefix — appear as the lume changeover happened. Collectors call these Swiss-only dials, a minor transitional variant.
Around 1998–1999, Rolex switched to Luminova lume on the 16610. Late dials drop the tritium markings and read SWISS MADE at 6 o’clock. Luminova glows green-white rather than the warm orange-yellow of aged tritium and does not patinate the same way. The visual character of the watch changes.
The transition was not instantaneous. Some P-series 16610s still have tritium and some A-series already carry Luminova. The 93150 bracelet with stamped end links remained in place through this period, keeping the overall feel of the early generation despite the lume change.
Phase 3 — SEL upgrade (~2001)
Serial range: Y series (roughly 2001 to 2002).
Around 2001, Rolex replaced the stamped 501B end links with solid Super End Links (SEL, code 93250). The change is tactile and structural. The SEL bracelet is heavier, more rigid, and sits differently against the case; it fills the lug gap more completely than the older stamped end links.
A 16610 with Y serial or later should carry SEL. A pre-Y serial fitted with SEL has probably had a bracelet upgrade; a Y-plus serial with 501B is unusual and worth verifying against the physical parts. Luminova was also upgraded to Super-Luminova around this period, improving brightness and longevity.
Y-serial examples (about 2001–2002) are prized for the overlap they capture. SEL had arrived but the drilled lug holes had not yet been removed (lugs were eliminated around the F serial in 2003). A Y-serial 16610 with both SEL and drilled lugs combines the upgraded bracelet with the heritage case detail, a configuration that existed for only a brief production window. Rolex Forum collectors track this combination as a distinct desirability tier within the reference.
The same change happened at about the same time on the 16610LV (launched 2003, arriving without stamped end links). The no-date sibling, the 14060M, retained stamped end links for somewhat longer before transitioning, one reason early 14060M examples are valued for their vintage specification.
Phase 4 — Lug holes removed and LEC crystal (~2003)
Serial range: F series (roughly 2003 to 2004).
Around 2003, Rolex plugged the lug holes on the 16610. From this point, the case is solid through the lug, so strap changes require tools. The Laser Etched Crown (LEC), a tiny Rolex coronet etched into the sapphire crystal at 6 o’clock (visible with loupe), was also introduced around 2003 as an anti-counterfeiting measure.
The 16610LV arrived in autumn 2003 already without drilled lug holes, meaning no production 16610LV ever had lug holes. The standard 16610 lost them at about the same time. From about the F serial band onward, lugs are solid on both references.
Phase 5 — Engraved rehaut and final spec (~2005–2010)
Serial range: D series (roughly 2005 to 2006) through V series (production end around 2010).
Around 2005, the 16610 received the engraved inner rehaut — repeating ROLEX ROLEX ROLEX text with the serial number at 6 o’clock. A further anti-counterfeiting measure that became standard across the Rolex sport line during this period. Late 16610 dials may also show slightly larger lume plots, approaching the Maxi dial format that became standard on the 116610LN successor.
By the final years of production (2008–2010), the watch carried the current-spec bracelet (ref.93250 with SEL and Oysterlock clasp), engraved rehaut, LEC crystal, and Super-Luminova dial. The last production runs (V, N, M series) represent the fully evolved version of the platform. This is what the 116610LN replaced with a new case and ceramic bezel.
All of the serial ranges above are collector approximations rather than Rolex-confirmed production records. Rolex produced in batches, and individual watches near any transition point may not match the expected specification. When authenticating a 16610, read the actual components — lug holes present or plugged, end link type, dial text, crystal etching — rather than relying on the serial band as a guarantee.
Movement notes
Caliber 3135 ran unchanged through the entire 23-year production. It is a 28,800-vph automatic with quick-set date and Microstella regulation, one of Rolex’s most important modern calibers and shared with the Datejust and other professional references. Power reserve is roughly 48 hours, and COSC certification appears on the dial from the start of the 16610 run.
Later 3135 specimens received the Parachrom blue hairspring, a paramagnetic alloy that resists magnetic fields and temperature variation better than the older Breguet overcoil spring. The exact transition point for Parachrom in the 16610 is not firmly pinned in this corpus.
Case, bezel, crystal, and crown
The case is the 40mm crown-guard Oyster carried over from the 16800. Sapphire crystal with a Cyclops magnifier sits over the date window, and a black aluminum insert with luminous pearl at 12 rides a serrated steel edge.
Four meaningful changes run across the production span. The drilled lug holes present from 1988 disappear around 2003. The Laser Etched Crown, a tiny coronet etched on the underside of the sapphire at 6 o'clock, arrives at roughly the same moment. The engraved rehaut with repeating ROLEX text and the serial number appears around 2005. And the bracelet evolves from stamped 501B end links on the 93150 to solid end links around 2001 and eventually the 93250 on an Oysterlock clasp.
Rotation is unidirectional with 120 clicks, each click worth half a minute of elapsed time. The insert is black anodized aluminum on the standard 16610; the 16610LV uses a green anodized insert.
Bezel material (aluminum), crystal type (sapphire with Cyclops), and crown type (Triplock) remained consistent across the 16610’s life. The 116610LN successor arrived with Cerachrom, a Maxi case with wider lugs, and the Glidelock bracelet: an entirely new platform carrying the same identity forward.
Bracelets, end links, clasps, and packaging notes
The bracelet evolution is detailed in the timeline above (Phases 1, 3, and 5). The exact serial cutover from ref.93150 to ref.93250 is not pinned in this corpus.
Clasp codes date the clasp, not the watch head. The clasp stamp is useful for establishing bracelet provenance but should not be used to date the head.
The early diver’s extension uses a fold-out design; later production refined this to a link-based system integrated into the Oysterlock clasp. The transition from hollow end links (HEL) to solid end links (SEL) is one of the most tracked collector milestones in the reference.
Packaging follows period-based logic. The 16610 spans several Rolex packaging generations, from older green boxes through the later presentation packaging. Box, papers, and warranty card completeness is a significant factor for collector pricing.
Special branches
Italian State Police
At least one documented 16610 carries the stamp of the Italian State Police Nautical Division. Institutional-issue Submariners from this era represent a collector branch analogous to the military MilSubs of the 5513/5517 era, though they are later, less rare, and less systematically documented.
COMEX
Rolex produced COMEX-marked 16610 Submariners between about 1986 and 1997, with an additional small batch around 2003–2004. The 16610 is the last Rolex model to feature the COMEX logo on its dial. With the exception of their dials and caseback engravings, COMEX 16610 watches are otherwise identical to standard-production 16610 examples: same caliber 3135, same case, same bracelet.
By the time of the 16610, diving technology had advanced past the point where COMEX divers relied on mechanical wristwatches. The COMEX 16610 watches became presentation and commemorative pieces rather than active diving tools, which means surviving examples tend to be in significantly better condition than older COMEX references (5513, 5514, 1680, 16800). These watches were never sold through stores, boutiques, or authorized dealers; they were issued directly to COMEX personnel.
The full lineage of COMEX-issued Rolex dive watches spans: Submariner 5513, 5514, 1680, 16800, 168000, 16610; Sea-Dweller 1665, 16660, 16600. The 16610 sits at the end of this lineage, as the Rolex-COMEX partnership ended before the next-generation Submariner was introduced.
COMEX 16610 examples are generally more affordable than older COMEX references (5514, 1680) but remain among the most collectible co-branded Rolex models. Watches with the COMEX logo on the dial command stronger premiums than those with caseback-only engravings.
16610LV variant
The 16610LV (“Kermit”) is a distinct reference, not a sub-variant. It uses the 16610 platform with a green aluminum bezel and Maxi dial. See the 16610LV article for coverage.
The name LV stands for Lunette Verte (French for green bezel). Within the 16610LV, collectors track the Flat 4 versus Sharp 4 bezel numerals, a subtle difference in how the numeral 4 at the 40 position on the insert is rendered. The 16610LV also introduced the Maxi dial (larger hour indices and broader hands) as a standard format, one that carried forward to the 116610LN.
Service dial warning and dial-text authentication
The tritium-to-Luminova transition created a short authentication shorthand that doubles as the fastest way to date a 16610. T SWISS T or SWISS T<25 at 6 o’clock indicates a tritium dial from the 1988 to roughly 1998 era. A bare SWISS reading places the dial in the short Luminova transition of 1998 to 2000. SWISS MADE covers the settled Super-LumiNova era from 2000 to the end of production.
Rolex servicing in the 2000s routinely fitted Luminova dials to tritium-era watches, since tritium dials were no longer manufactured. A pre-A serial (pre-1999) wearing a SWISS MADE dial has almost certainly had a service replacement. The Luminova dial is not incorrect, since Rolex fitted it, but it is not the original configuration, and collectors treat the swap as a significant deduction.
A tritium dial on a tritium-era serial carries a premium for the honest patina and the confidence that the watch has not been redialed. When buying a pre-Y serial 16610, read the dial text before anything else.
Historical market and auction record
The 16610 is one of the most available pre-ceramic Submariners on the secondary market, which keeps prices lower than the rarer 16800 or the shorter-production 16610LV. A 23-year production run means high absolute production numbers, and the reference was never limited or specialty. A Rolex salesman reportedly stated on Rolex Forum that the 16610 was produced at a ratio of about 5–6 units for every one 16610LV, a figure that, if accurate, underscores both the volume of the standard reference and the relative scarcity of the Kermit.
As the gap between aluminum-bezel and ceramic-bezel Submariners widens, the 16610 has moved into its own collecting tier. The most tracked points within the reference are tritium-dial examples, Swiss-only transitional dials, and early examples still carrying both lug holes and stamped end links.
