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 roughly 23 years on a single reference number. No other Submariner Date reference comes close: the 16800 lasted about eight years, the 116610LN ten. The 16610 ran for more than two decades while the rest of the Rolex sports line moved around it, accumulating small specification changes that reward careful inspection.
Across that span the 16610 worked through three lume technologies, two bracelet systems, and a sequence of anti-counterfeiting measures, all without a new reference number. Caliber 3135 stayed put.

Where it sits in the line
The 16610 follows the transitional 16800 and precedes the 116610LN. The 16800 had introduced sapphire crystal and the 300m rating to the date Submariner; the 16610 settled the platform around caliber 3135, the definitive Triplock crown, the 40mm Oyster case, and the graduated 60-click aluminum bezel insert, and held that specification for over two decades. The broader public associates the Submariner Date with the 16610 because it ran for so long, in such volume, and looked so consistent.
It ran alongside the no-date 14060 and 14060M. Together those references make up the five-digit Submariner era. Same case, same bracelet architecture, many of the same specification milestones; the 16610 carries the date, the 14060 / 14060M does not.
The 16610 also spawned the 16610LV anniversary variant, the "Kermit," in 2003. The Kermit uses an 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. 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 on a 20- to 30-year-old dial the lume runs from light patination to the deep cream, tan, and orange tones collectors call tropical. Lug holes drill straight 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 reads as an update of the specification that started with the 5513 rather than a departure from it.
Phase 2 — Luminova transition (~1998–2001)
Serial range: A to P series (roughly 1998 to 2000).
A short window sits between the full tritium era and the settled Luminova era. Dials marked SWISS only, without the T prefix, appear during the lume changeover. Collectors call these Swiss-only dials, and they are a minor but tracked transitional variant.
Around 1998–1999 Rolex switched to Luminova on the 16610. Late dials drop the tritium markings entirely 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, which gives the late watch a different visual character on the wrist.
The transition was not instantaneous. Some P-series 16610s still carry tritium and some A-series already wear 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 as much as visual: the SEL bracelet is heavier, more rigid, and fills the lug gap more completely than the older stamped end links. Luminova was upgraded to Super-Luminova at about the same time, improving brightness and longevity.
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.
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. A Y-serial 16610 with both SEL and drilled lug holes combines the upgraded bracelet with the heritage case detail, a configuration that existed for only a brief production window and that long-time collectors treat as a distinct desirability point within the reference.
The same end-link 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 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, a tiny Rolex coronet etched into the underside of the sapphire at 6 o'clock and visible with a loupe, was added at roughly the same time as an anti-counterfeiting measure.
The 16610LV launched in autumn 2003 already without drilled lug holes, so no production 16610LV ever carried them. The standard 16610 lost its lug holes at about the same point, and from the F serial band onward both references run with solid lugs.
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, with repeating ROLEX ROLEX ROLEX text and the serial number at 6 o'clock. The engraving became standard across the Rolex sport line during this period as a further anti-counterfeiting step. 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, and that is what the 116610LN replaced with a new case and ceramic bezel.
The serial ranges above are collector approximations rather than Rolex-confirmed production records. Rolex produced in batches, and individual watches near a 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, shared with the Datejust and other professional Rolex references of the era. 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 established.
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 a 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, 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. The bracelet evolves alongside, 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 a Cerachrom bezel, a Maxi case with wider lugs, and the Glidelock bracelet, a new platform under the same name.
Bracelets, end links, clasps, and packaging notes
The 16610 bracelet runs through three configurations across the production span: ref.93150 with stamped 501B end links and Fliplock clasp from 1988, the SEL upgrade around 2001, and ref.93250 with Oysterlock clasp on later production. The exact serial cutover from ref.93150 to ref.93250 has not been firmly established.
A clasp code dates the clasp, not the watch head. The stamp is useful for establishing bracelet provenance but cannot 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 among the most closely 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 form 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 approximately 1989 and 1997, with an additional small batch around 2003–2004. The Rolex-COMEX partnership itself ran earlier across the 5513 / 5514 / 1680 / 16800 generation; the 1989–1997 window is specifically the 16610 portion. The 16610 is the last Rolex model to carry the COMEX logo on its dial. With the exception of dial and caseback engravings, COMEX 16610s are otherwise identical to standard production: same caliber 3135, same case, same bracelet.
By the time of the 16610, diving technology had moved past the point where COMEX divers relied on mechanical wristwatches. The COMEX 16610s functioned as 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). They 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, and 16610, plus Sea-Dweller 1665, 16660, and 16600. The 16610 sits at the end of this lineage; the Rolex-COMEX partnership ended before the next-generation Submariner was introduced.
COMEX 16610s 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 its own reference rather than a sub-variant of the 16610. It uses the 16610 platform with a green aluminum bezel and Maxi dial.
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, with larger hour indices and broader hands, as a standard format, a layout that carried forward to the 116610LN.
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 because tritium dials were no longer being 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 no longer 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 below the rarer 16800 and the shorter-production 16610LV. A 23-year production run means high absolute production numbers, and the reference was never limited or specialty. The 16610-to-16610LV production ratio is widely reported on collector forums at roughly five or six to one in favour of the standard reference, but no published source confirms that figure.
As the gap between aluminum-bezel and ceramic-bezel Submariners widens, attention within the 16610 has concentrated on tritium dials, the Swiss-only transitional dials, and early examples still carrying both lug holes and stamped end links.
