Quick answer
The Rolex 126710BLNR is the GMT-Master II with a blue and black ceramic bezel, and its common synonyms are "BLNR," "Batman" (Oyster bracelet) and "Batgirl" (Jubilee bracelet). The word "replica" is a search modifier rather than a Rolex term: Rolex does not make or sell replicas, and no genuine watch is labeled that way.

What the reference number tells you
Rolex reference codes carry the configuration inside them. On the 126710BLNR, "126710" identifies the current 40 mm Oystersteel GMT-Master II case with a 24-hour bezel and the Caliber 3285 movement. The suffix "BLNR" comes from the French words for blue and black, a shorthand collectors use for the two-tone bezel insert. That Cerachrom insert is one piece of ceramic, so the blue and black halves meet in a clean line at the 6 and 18 positions.
Earlier BLNR watches used the 116710 reference, which shipped on an Oyster bracelet. When Rolex moved the blue and black bezel onto the 126710 case in 2019, the standard bracelet became a Jubilee, and the collector nickname shifted from Batman to Batgirl. An Oyster bracelet option followed, which is why you will see both names attached to the same reference number.

Why "replica synonym" searches appear
Shoppers sometimes search for a replica synonym because they want to find a specific counterfeit listing by nickname. Others are trying to work out whether a watch they saw online is genuine or a copy wearing a familiar nickname. Both searches land on the same pages, and that is the problem. A listing that leans on the Batman or Batgirl name without stating the reference number is a listing you cannot verify.
Risks that come with replica watches
- Counterfeit watches infringe trademarks, and importing, selling or trafficking them is illegal in the United States and most other markets.
- Customs officers seize counterfeit shipments, and the buyer usually loses the money.
- Rolex will not service or authenticate a counterfeit, so repairs fall to independent shops.
- Counterfeit cases often use plated brass or lower-grade steel, and the plating wears through.
- Payment methods favored by counterfeit sellers rarely offer a refund path.
How to check a BLNR for authenticity
- Look at the bezel seam. Genuine ceramic inserts have a sharp transition with no paint bleed.
- Check the date window and cyclops magnification. The lens should enlarge the date evenly across the aperture.
- Inspect the bracelet end links and clasp stamping. Engraving is crisp and consistent, not shallow or uneven.
- Confirm the reference on the case between the lugs matches the paperwork and the model name.
- Have the movement checked by a watchmaker. The Caliber 3285 has a 70-hour power reserve and a smooth sweeping seconds hand.
Better routes to the look you want
If the goal is the blue and black GMT look, there are honest options. Steinhart, Seiko and other brands build GMT watches with similar colorways at accessible prices, and they come with real warranties. If the goal is the actual 126710BLNR, buy pre-owned from a dealer who provides service history, or join an authorized retailer waiting list. A documented pre-owned watch holds value, while a counterfeit holds none.
Bottom line
BLNR, Batman and Batgirl are collector nicknames for one GMT-Master II family, and "replica" is a search term that counterfeit sellers use to catch buyers. Knowing the reference number, the bezel construction and the bracelet differences is the fastest way to tell a real 126710BLNR from a copy.
