Reference:116610LN
In 2010, Rolex did something it had not done to the steel Submariner in decades: it changed the bezel material. The 116610LN became the first steel Submariner Date with a Cerachrom ceramic bezel insert, replacing the aluminum insert that had served every steel Submariner since the 1950s. That single change, more than any other detail in the specification, defines what the 116610LN is and why collectors treat it as a generational break.
Aluminum had accompanied the Submariner through fifty-plus years of production, but it came with a fundamental limitation: it faded. Collectors of the five-digit and earlier eras spent significant effort assessing bezel condition — a fresh insert versus a ghosted one could define whether a watch was pristine or worn. Cerachrom ended that calculus entirely. Ceramic does not fade, does not scratch easily, and will look in twenty years exactly as it looks today. Condition anxiety about the bezel disappeared.
A second headline upgrade arrived alongside: the Glidelock clasp. Where the outgoing 16610 used a Fliplock extension for over-wetsuit wear, Glidelock introduced approximately 20mm of micro-adjustment in 2mm increments, operable on the wrist without tools. Taken together — ceramic bezel, Glidelock clasp, Maxi Case, Chromalight lume — the 116610LN was not a minor refresh. It was a comprehensive modernization of the steel Submariner Date.
The precious-metal 116619LB had debuted the Cerachrom bezel two years earlier in 2008, serving as proof of concept. The 116610LN was the mass-market rollout. For most buyers, this was their first encounter with a ceramic-bezel Submariner, and it reset expectations for what a steel sport Rolex could be.

Where it sits in the line
The 116610LN directly succeeded the 16610, which had run for approximately 23 years. Both use caliber 3135. Both are 40mm steel Submariner Date watches with sapphire crystals. But the 116610LN is the generational break between the five-digit and six-digit eras.
The parallel green-bezel version is the 116610LV ("Hulk"), discussed in its own article. A white gold counterpart, the 116619LB, received the Cerachrom bezel two years earlier in 2008, making it the first Submariner of any material with a ceramic bezel — and the 116610LN the first in steel.
Precious-metal siblings in the same generation include the 116613 (Rolesor two-tone), the 116618 (full yellow gold), and the 116619LB (full white gold). All share caliber 3135, the Super Case architecture, Glidelock bracelet, and Cerachrom bezel. The 116610LN is the entry point of that family.
What changed from the 16610
The 116610LN represents the single biggest external redesign of the steel Submariner Date since the introduction of sapphire crystal and quickset date in the 16610 itself. The bezel material change alone is seismic by Submariner standards — aluminum had been the default since the 1950s, defining how collectors assessed condition. Cerachrom eliminated the bezel-fading problem entirely. A well-preserved aluminum bezel was a meaningful point of distinction; a ceramic bezel simply does not become one because it does not degrade.
| feature | 16610 | 116610LN |
|---|---|---|
| bezel insert | aluminum, fades over time | Cerachrom ceramic, fade-proof |
| lug width | slimmer | wider ("Super Case" / "Maxi Case") |
| lug holes | present | absent |
| lume | SuperLuminova (green glow) | Chromalight (blue glow) |
| markers | standard size | Maxi (larger) |
| bracelet clasp | Fliplock with divers extension | Glidelock (20mm micro-adjust) |
| crystal coating | none | anti-reflective inner coating |
| rehaut | plain (early) / engraved (late) | engraved throughout |
Case diameter remains 40mm and the movement remains caliber 3135, but the wrist presence is different. Wider lugs and a heavier bracelet make the 116610LN feel like a larger watch than the 16610, even at the same diameter.
Production outline
The 116610LN does not have the layered internal variation that defines vintage references. The ceramic bezel does not fade or patina. The movement stays as caliber 3135 for the full ten years. Forum-documented evidence of a dial font change (see Dial map) suggests the reference is not entirely invariant, but it remains a one-era reference in practical terms.
Rolex introduced the 116610LN at Baselworld 2010 alongside the green 116610LV. Both replaced the equivalent five-digit references (16610 and 16610LV) and carried the same set of upgrades: ceramic bezel, Maxi Case, Glidelock bracelet, and Chromalight lume.
Production ended in 2020 when Rolex introduced the 126610LN with caliber 3235 and a 41mm case. The transition was clean: one reference out, one reference in.
Movement notes
Caliber 3135 is a COSC-certified automatic with a date function, running at 28,800 bph with approximately 48 hours of power reserve. Rolex had been using this movement since the late 1980s in the 16610, and it continued unchanged into the 116610LN.
The Parachrom hairspring — antimagnetic and more shock-resistant than the older Elinvar-type springs — was introduced across the sport lines during this period.
The successor 126610LN moved to caliber 3235, which added a longer 70-hour power reserve and the Chronergy escapement. That upgrade is the single biggest functional change between the two references.
Dial map
Black dial with white gold applied Maxi markers. "Maxi" means the markers are physically larger than the markers on the outgoing 16610. Triangle at 12, rectangles at 3/6/9, round hour dots — all bigger.
Chromalight lume glows blue in the dark instead of the green glow from SuperLuminova on the late 16610. Rolex claims Chromalight lasts longer than conventional lume, and it is visually distinctive. In a dark room, a 116610LN glows blue while a 16610 glows green — the quickest way to distinguish the generations in low light.
Published reference guides have treated the 116610LN dial as consistent from 2010 to 2020 with no mid-run variants. But Rolex Forum members have documented at least one typographic change: the capital "A" in "SUBMARINER" exists in two forms. Earlier production examples carry an "A" with a flat top, while examples from approximately November 2016 onward show a pointed "A." The change is subtle and requires side-by-side comparison, but multiple forum threads with photographic evidence support the distinction. If confirmed across a larger sample, the 116610LN is slightly less uniform than previously assumed — though it remains far simpler than the variant-rich vintage references.
Case, bezel, crystal, and crown notes
Case
The case is 40mm in 904L Oystersteel. Collectors call it the "Maxi Case" or "Super Case" because the lugs are wider and more substantial than the outgoing 16610. Approximately 12.5mm thick with a lug-to-lug span of approximately 48mm. No lug holes. Solid, fluted screw-down caseback.
Wider lugs change the visual proportions. The 116610LN does not look like a 16610 with a ceramic bezel; it looks like a redesigned watch. This is the principal reason collectors who prefer the slimmer five-digit aesthetic do not automatically migrate to the 116610LN.
Bezel
The Cerachrom ceramic bezel is the defining external change — and the defining historical marker for the steel Submariner. Aluminum had been the bezel insert material since the earliest Submariners of the 1950s. Collectors of aluminum-bezel Submariners (from the 6200 through the 16610) always had to evaluate insert condition: fade level, ghost effect, chips, fading pattern. None of that applies here. Unidirectional with 60 clicks, numerals and graduation marks filled with platinum via PVD deposition, giving them a silver-grey appearance against the black ceramic.
Cerachrom does not fade, scratch easily, or develop the patina that collectors prize on vintage references. A practical improvement and a collector trade-off: the 116610LN bezel will look the same in twenty years.
Crystal
Sapphire with a Cyclops magnifier at 3 o'clock over the date window. The inner surface has an anti-reflective coating that gives the crystal a slight blue or purple tint when viewed at an angle. This coating was not present on the 16610 and is one of the less obvious generational differences.
Crown
Triplock screw-down crown with crown guards, rated to 300m / 1000ft.
Bracelets, end links, clasps, and packaging notes
Bracelet
Solid links throughout on the Oyster bracelet. The clasp is the Oysterlock with Glidelock extension system — approximately 20mm of on-the-fly length adjustment in 2mm increments without tools. New for the Submariner with the 116610 generation, replacing the older Fliplock system with its single-position divers extension.
Glidelock is the single most praised functional upgrade in the 116610 generation. Fine-tuning bracelet length without tools — in the pool, in warm weather, over a wetsuit — is the kind of practical improvement that changes daily wear.
The bracelet reference is likely 93250, consistent with six-digit Submariner fitment. Bracelet width is 20mm at the lugs. Solid end links are fitted.
Packaging
The 116610LN shipped in the standard Rolex green box of the 2010s era with warranty card, COSC tag, booklets, and hang tags. During the production run, Rolex transitioned from the older green warranty card format to the newer credit-card-style warranty card.
Rehaut
The inner rehaut ring is engraved with repeating "ROLEX ROLEX ROLEX" text around the circumference and the individual serial number engraved at the 6 o'clock position. Introduced on the late 16610 and carried over to the 116610LN from production start.
Production volume estimates
Industry estimates from the ~2010 era suggest Rolex produced approximately 35,000 steel Submariner Date watches per year. If those figures held roughly steady across the 116610LN's ten-year run, cumulative production could be substantial — though Rolex does not publish production numbers and these figures are approximations circulated among dealers and collectors.
Market and collector context
The 116610LN is a modern production reference, not a vintage piece. It does not attract the lot-level auction attention that vintage Submariners receive at Phillips or Sotheby's. Market activity is primarily dealer-to-dealer and secondary retail.
To anchor the market position: the successor 126610LN retails new at $11,350 USD. The no-date steel Submariner 114060 trades on the secondary market around $12,400. The 116610LN (date version) typically trades above the no-date, reflecting collector preference for the date complication within this generation.
Since discontinuation in 2020, the 116610LN has traded above its original retail price on the secondary market, though premiums have moved with the broader Rolex market cycle. It sits below its green sibling, the 116610LV "Hulk," in secondary market pricing — the Hulk commands a substantial premium that the 116610LN does not approach.
The market position is straightforward: the last 40mm ceramic Submariner Date in steel, sitting between the five-digit 16610 era and the current 41mm 126610LN. Collectors who prefer the 40mm case size have a fixed supply to draw from. The 126610LN's 41mm case is close enough that many buyers are satisfied with current production, which keeps the 116610LN premium moderate compared to the Hulk.
This is also the last steel Submariner Date where caliber 3135 was standard. The 126610LN's 3235 brings 70-hour power reserve and the Chronergy escapement — meaningful upgrades. But for collectors who consider the 3135 proven and sufficient, the 116610LN is the last entry in that chapter.
