A fake Rolex 126612LB is a replica of the two-tone blue Submariner Date, the steel and yellow gold model collectors call the Bluesy. Rolex catalogs that watch as reference 126613LB, and 126612LB is a listing code used on replica and some grey-market storefronts for the same 41 mm, blue-dial, blue-bezel configuration. Since the number is a seller convention and not a factory specification, build quality, not the reference on the page, is the only thing worth judging.

Is 126612LB a real Rolex reference number?

No. Rolex's published two-tone blue Submariner Date is reference 126613LB, and the full two-tone family uses the 126613 prefix. The 126612LB code appears because sellers group the blue Rolesor variant into one searchable listing tag.

If a listing presents 126612LB as a genuine Rolex catalog number, treat that as a warning sign. Check any reference against Rolex's own product pages before you trust a spec sheet.

What specs should a 126612LB replica match?

  • 41 mm Oyster case, roughly 47.6 mm lug to lug, about 12.5 mm thick.
  • Rolesor construction: Oystersteel case and bracelet with 18k yellow gold bezel, crown, and center links.
  • Blue Cerachrom bezel insert with gold-tone numerals and a 120-click unidirectional action.
  • Blue sunray dial with Chromalight luminescent markers and hands.
  • Oyster bracelet with a Glidelock-style clasp and a total weight near 155 to 165 grams.
  • A clone of the calibre 3235, running at 4 Hz with about a 70-hour power reserve.

What are the replica grade tiers?

  • Entry tier: painted metal bezel inserts, 316L steel, gold-tone plating, cheap automatic movements, loose tolerances.
  • Mid tier: ceramic insert, better dial printing, 316L or 904L steel, improved bracelets, still noticeable flaws up close.
  • High tier: 904L steel, correct gold hue, sapphire with anti-reflective cyclops, smoother bezel action and tighter end links.
  • Super clone: near 1:1 case geometry, engraved rehaut and serial, cloned 3235 movement, best dial and lume accuracy, highest price and the most scrutiny needed.

How do you inspect a 126612LB replica before buying?

  1. Check the bezel insert material. Real ceramic has depth and clean numerals; painted metal looks flat and scratches.
  2. Study the dial. Sunray brushing should shift light evenly, and printing should be crisp with no bleeding on the coronet.
  3. Look through the cyclops. Magnification near 2.5x with a clear date and light distortion at the edges is correct.
  4. Read the rehaut. Engraving should sit at 6 o'clock and wrap cleanly around the flange.
  5. Test the bracelet. Solid end links should sit flush with no gaps or rattle, and the clasp should snap shut with resistance.
  6. Ask for timegrapher numbers. Rate within about plus or minus 10 seconds a day and a healthy amplitude point to a decent movement.

What are the most common flaws?

  • Gold that reads too orange or too pale next to genuine 18k yellow gold.
  • Bezel inserts that fade or turn purple under sunlight.
  • Lume that glows the wrong shade or dies within minutes.
  • A gritty crown, sticky date change, or a date font that is too bold.
  • Bracelet stretch and uneven gaps between links after light wear.

Is a 126612LB replica water resistant?

Most replicas claim 300 m but realistically handle splashes only. Factory gaskets and caseback seals are rarely pressure tested, so swimming is a risk.

If you plan to wear it near water, have a watchmaker pressure test it and reseal the caseback first. Even then, do not treat a replica as a dive watch.

Is buying or selling one legal?

Counterfeit watches infringe trademarks, and in the United States they are illegal to import and to sell. U.S. Customs and Border Protection can seize shipments of counterfeit goods, and sellers face civil liability.

That does not change how the watches are built, but it does shape where they ship from and what recourse you have if a parcel is stopped.

Quick answers

What does the LB suffix mean on Rolex references?

LB is Rolex shorthand for a blue bezel and dial combination, which is why the two-tone blue Submariner Date carries it.

How much should a good 126612LB replica cost?

Expect roughly 250 to 400 dollars for a solid mid tier build and 450 to 800 dollars or more for a high tier or super clone example. Anything far below that usually shows in the bezel, dial, and bracelet.

Can a watchmaker tell instantly?

Often yes, through the movement, caseback threads, and bracelet finishing. The dial and bezel are usually the parts that fool the eye first and the movement that gives it away last.
