Short answer
A replica Rolex black Sub is a copy of the Submariner with a black dial and black bezel, usually modeled on the 116610LN or the newer 126610LN. Under the "first copy" label you will find everything from a $50 quartz knockoff to a $500 super clone with a cloned automatic movement. It is the most copied watch shape in the world, so the spread between the cheapest and the best is wider here than on any other model. Two listings that look identical in photos can differ by a movement, a bezel insert, and a bracelet that rattles.
What "black sub" actually covers
The phrase gets used for several references, and they are not the same watch.
- Submariner Date: 116610LN (40 mm, 2010 to 2020) and 126610LN (41 mm, current). Black dial, black ceramic bezel, date at 3 under a cyclops.
- No-date Submariner: 114060 and 124060. Same black dial and bezel, no date window, cleaner symmetry.
- Older references: 16610 and 14060 with aluminum bezel inserts. These show up in replica form too, though less often.
If a listing never says which reference it copies, that is the first sign you are looking at a generic shape rather than a specific model.
The tier words, and what they are worth
"First copy," "AAA," "1:1," and "super clone" are vendor language, not standards. Nobody certifies them. One seller's "1:1" is another seller's mid tier. The useful question is never the label, it is which parts went into the build. I skip the tier names and read the spec list instead.
Parts that decide quality
Bezel insert
Modern Subs use a ceramic insert with engraved, filled numerals. On good copies you can see and feel the depth of the numbers. On cheap ones they are printed on aluminum or coated steel, and they go dull and scratched within months. The bezel should turn in 120 clicks with no mush and land centered on the 12 marker.
Crystal
Sapphire with an anti-reflective coating under the cyclops is the baseline for anything calling itself a super clone. Mineral glass is common at entry tier. Look at the crystal edge-on: cheap ones look hazy, and the cyclops either magnifies too little or throws a blue glare that does not belong there. Magnification on the real thing is about 2.5x.
Movement
This is where most of the money goes. You will run into Seiko NH35 and ETA 2824 clones at the mid tier, and decorated clones of the 3135 or 3235 at the top. The tell is the seconds hand. A genuine-spec movement beats at 28,800 vph and sweeps smoothly, a 21,600 movement looks slightly slower, and quartz ticks. Date change is the second tell: instant at midnight on a good movement, a slow crawl on a cheap one.
Case and bracelet
Check the lugs, the crown guards, and whether the end links sit flush against the case with no gap. Solid links, a proper glide-lock style clasp, and screwed links instead of friction pins are what separate the top tier from the rest. A full steel Submariner on a complete bracelet weighs roughly 155 to 160 grams, so a copy that feels like a feather is telling you what the case is made of.
Dial and lume
Print weight and spacing matter more than most people expect. The crown at 12, the text lines, and the "Swiss made" at the bottom should all sit correctly. Modern black Subs use a blue-glowing lume. Charge it under a light and watch whether it fades evenly or goes patchy after ten minutes.
A five minute check routine
- Wind and set the watch, then watch the seconds hand through a full sweep.
- Advance the date and confirm it flips cleanly at midnight.
- Turn the bezel through a full rotation and check the 12 alignment.
- Look at the crystal straight on and at an angle for haze or a wrong-tint cyclops.
- Flex the bracelet and listen. Rattles and loose end links show up right away.
- Weigh it if you can. Under about 120 grams on a steel bracelet means a hollow case or a folded-link bracelet.
Fit and sizing
The current 126610 is 41 mm with a lug-to-lug around 47.6 mm, which wears larger than the number suggests. The older 116610 at 40 mm sits closer to the wrist. If you are between sizes, the bracelet matters as much as the case: half links and a proper micro-adjust clasp will do more for comfort than 1 mm of case diameter.
The legal side, plainly
In the United States, counterfeit watches are illegal to import and to sell. Customs can seize shipments, and trademark owners can bring civil claims against sellers. Personal use is a gray area in practice, but resale is not. There is a practical side too: no replica holds value, no Rolex service center will touch it, and there is no warranty behind it. A copy is a copy, priced as a copy, and it is worth buying with that clear in your head.
Bottom line
If you are reading about a replica Rolex black sub, decide what you are actually buying. A cheap first copy gets you the silhouette and nothing else. The money at the higher tiers goes into the movement, the ceramic insert, the sapphire crystal, and the bracelet. Those four things are worth asking about before anything else in the listing.
