Rolex Bezel & Dial Code Decoder
See ‘116610LV’ in a listing, or hear a watch called a ‘Batman’ or a ‘Pepsi’, and wonder exactly which Rolex that is? The suffix codes are abbreviations of the French bezel colour — and collectors layer nicknames on top. Enter a code or a nickname below to decode both at once.
Rolex Code & Nickname Decoder
Enter an official suffix (LN, LV, BLNR, BLRO…) or a collector nickname (Pepsi, Batman, Hulk, Smurf…). The decoder returns the meaning, the colours, and the model it belongs to.
The suffix is only part of the story — pair it with the numeric reference number to identify the exact watch.
Rolex references are made up of a numeric reference number plus, in many cases, a two-to-four letter colour suffix. Those letters are not random: they are the first letters of the French words for the bezel colour, because Rolex — though famously Swiss — has always used French, one of Switzerland’s national languages, for its internal descriptions. On top of this official system, the collector community has invented a rich set of nicknames — Pepsi, Batman, Hulk, Kermit, Smurf — that describe the same watches in plain slang. This guide decodes both layers so that any code or nickname you encounter resolves to a specific, unambiguous watch.
Why the codes are in French
Switzerland has four national languages, and French is the working language of the Suisse Romande region where much of the watch trade sits. Rolex adopted French colour terms for its bezels, and the suffix is simply the initials of those words. Once you know the vocabulary, most codes decode themselves:
- Lunette — French for “bezel”, giving the leading L in codes like LN, LV and LB.
- Noir(e) — black → N
- Vert(e) — green → V
- Bleu(e) — blue → B or BL
- Rouge — red → RO
- Chocolat — brown → CH
Two-colour bezels combine the initials in order: BLNR is BLeu + NoiR (blue-black), and BLRO is BLeu + ROuge (blue-red). The suffix always describes the bezel, not the dial — the exception being crystal codes like the Milgauss GV (Glace Verte, green sapphire crystal).
Official Rolex suffix codes
These are the colour suffixes Rolex actually uses at the end of a reference number:
- LN — Lunette Noire, black bezel (e.g. Submariner 116610LN)
- LV — Lunette Verte, green bezel (e.g. Submariner 116610LV “Hulk”)
- LB — Lunette Bleue, blue bezel (e.g. Submariner 116619LB “Smurf”)
- BLNR — Bleu-Noir, blue-and-black bezel (GMT-Master II “Batman”)
- BLRO — Bleu-Rouge, blue-and-red bezel (GMT-Master II “Pepsi”)
- CHNR — Chocolat-Noir, brown-and-black bezel (GMT-Master II “Root Beer”)
- GV — Glace Verte, green sapphire crystal (Milgauss 116400GV)
The pattern is consistent: read each pair of letters as the first letters of a French colour word, in the order the colours appear on the bezel.

Popular Rolex nicknames decoded
Collectors nickname watches by their look. Each nickname maps to one or more specific references:
- Batman / Batgirl — GMT-Master II with blue-black Cerachrom bezel, ref. 116710BLNR & 126710BLNR (Batgirl is the Jubilee-bracelet version)
- Pepsi — GMT-Master II with blue-red bezel, ref. 16710 (vintage) & 126710BLRO (modern)
- Root Beer — GMT-Master II with brown-black bezel, ref. 126711CHNR
- Coke — vintage GMT-Master with red-black bezel (ref. 16700 / 16760)
- Hulk — Submariner with green dial and green bezel, ref. 116610LV
- Kermit — Submariner with green bezel and black dial, ref. 16610LV (50th anniversary)
- Starbucks / Cermit — Submariner with green ceramic bezel and black dial, ref. 126610LV
- Smurf — white-gold Submariner with blue dial and blue bezel, ref. 116619LB
- Bluesy — two-tone (steel/gold) Submariner with blue dial and bezel, ref. 116613LB
- Panda — Daytona with white dial and black sub-dials
- John Mayer — Daytona ref. 116508 with green dial (named after the musician-collector)
- Milgauss GV — Milgauss with green-tinted sapphire crystal, ref. 116400GV
Important: these nicknames are collector and community slang — they are not official Rolex product names. Rolex only ever refers to a watch by its reference number and, where relevant, the French colour suffix. Treat a nickname as a helpful shorthand, never as proof of what a watch is.
Not sure the code matches the watch?
Upload photos of the dial, bezel, and caseback and let our AI confirm the reference, the bezel colour, and whether the watch is consistent with the code or nickname it’s being sold under. Results in under 60 seconds.

Does the suffix match the physical bezel?
The single most useful check is trivial: an LV reference must have a green bezel, a BLRO must be blue-red, a CHNR must be brown-black. If a caseback or paperwork says one suffix but the bezel is a different colour, the insert has been swapped or the papers do not belong to that watch. This is one of the fastest ways to catch a “franken” assembled from mixed parts.
Does the seller use the right nickname?
A seller who calls a blue-red GMT a “Batman” (which is blue-black), or advertises a green-dial-and-bezel Submariner as a “Kermit” (which has a black dial), either doesn’t know the product or is being careless. It is not proof of a fake on its own, but a mismatched nickname is a prompt to slow down and verify every other detail.
Swapped bezel inserts on vintage pieces
Because aluminium inserts on older GMT-Masters and Submariners were replaceable service parts, a “Pepsi” or “Coke” bezel can be fitted to a case that never left the factory with it. Faded, all-original inserts command large premiums, so verify that the insert’s wear, font, and colour are consistent with the watch’s claimed age. A crisp modern insert on an otherwise heavily-patinated watch is a red flag for value, if not for authenticity.
Cross-check the reference number
The suffix is meaningless without the numeric reference it attaches to. Confirm the full reference — for example that a “Hulk” is genuinely a 116610LV and not a 116610LN with a replaced dial and bezel — using our Rolex reference number lookup and serial number lookup.
Bezel & dial code red flags
- ✖ Suffix doesn’t match the bezel colour. An LV reference with a black bezel, or a BLNR with a blue-red bezel, means the insert has been swapped or the paperwork is wrong.
- ✖ Wrong nickname for the watch. Calling a blue-black GMT a “Pepsi”, or a black-dial green Submariner a “Hulk”, shows the seller doesn’t know the reference — verify everything else.
- ✖ Made-up suffix. Rolex suffixes follow the French-initials pattern (LN, LV, LB, BLNR, BLRO, CHNR, GV). An invented code like “GRN” or “BLK” is not Rolex nomenclature.
- ✖ Fresh insert on an aged watch. A crisp, unfaded bezel on a case with heavy wear suggests a replaced (or reproduction) insert — a value red flag on vintage GMT and Submariner models.
- ✖ Nickname used as “proof” of authenticity. Nicknames are slang. A listing that leans on “genuine Hulk” without the reference, serial, and matching paperwork is telling you nothing verifiable.
Common questions
Why does the same nickname cover several references?
Because the nickname describes the look, not a single production run. “Pepsi” has applied to the vintage 16710 with an aluminium insert and the modern 126710BLRO with a ceramic insert — both blue-red GMTs. Always pair the nickname with the full reference to know exactly which one is being discussed.
Is “Hulk” the same as “Kermit”?
No, and it’s a common mix-up. Both are green Submariners, but the Hulk (116610LV) has a green dial and green bezel, while the Kermit (16610LV) has a green bezel with a black dial. The ceramic-bezel black-dial successor (126610LV) is nicknamed Starbucks or Cermit.
What does GV mean — it isn’t a bezel code?
Correct. GV stands for Glace Verte — “green glass” — and refers to the green-tinted sapphire crystal of the Milgauss 116400GV, not a bezel. It is the main exception to the “suffix = bezel colour” rule.
Do all Rolex references have a colour suffix?
No. The suffix is only added when a colour needs disambiguating — typically on Submariner, GMT-Master and a few other sports models offered in multiple bezel colours. A Datejust or Day-Date reference generally has no colour suffix; its dial and bezel are encoded elsewhere in the reference and on the papers.
Important Note
Decoding a suffix or nickname tells you what a watch should be, not that a given watch actually is genuine. Combine the code check with reference and serial verification, dial and bezel finishing, and overall build quality. For a high-value Rolex, an in-person inspection by a certified watchmaker is always the gold standard.
