Rolex GMT-Master II Batman · Reference 126710BLNR
Rolex GMT-Master II Batman 126710BLNR
Known as Batman (on Oyster) / Batgirl (on Jubilee)
The 126710BLNR is the current-generation steel GMT-Master II with the blue-and-black Cerachrom bezel. Rolex introduced it in 2019 as the direct replacement for the 116710BLNR, which had run from 2013. The letters BLNR come from the French bleu noir, blue black, which is exactly what the bezel gives you: blue for the daylight half of the 24-hour scale, black for the night half. It ships in a 40mm Oystersteel case, and the bracelet decides the nickname. On the three-link Oyster bracelet it is the Batman. On the five-link Jubilee it is the Batgirl. Same reference number, same watch, two personalities depending on how you strap it to your wrist. This is the traveler's Rolex: a true GMT with an independently jumpable local hour hand, so you land, pull the crown, and reset your home time without stopping the seconds.
Produced: 2019 to present. Launched in 2019 on the Jubilee bracelet as the Batgirl, with the Oyster bracelet option (the Batman configuration) added to the lineup in 2021. Still in current production and catalogued by Rolex.

Market & Value
MSRP after Rolex's January 2026 adjustment sits around $11,800 to $12,000 in steel. Authorized-dealer supply at that price is effectively nonexistent for a walk-in buyer, which is why the secondary market runs well above retail. Unworn and lightly worn 126710BLNR trade in roughly the $16,000 to $20,000 range as of mid-2026, with the Jubilee (Batgirl) usually carrying a small premium over the Oyster (Batman). Two market forces matter right now. First, the steel Pepsi GMT (126710BLRO) was discontinued in 2026, which leaves the Batman as the most attainable two-color-bezel steel GMT still in the Rolex catalog and puts more attention on this reference. Second, full sets with box, papers, and a fresh card date carry the strongest bids; a naked head or a mismatched card knocks real money off. Values are firm but not frothy, and the spread between a clean full set and a bare watch is wide enough to matter when you sell.
What to Know Before You Buy
The bezel is the whole story and it is genuinely hard to make. When the blue-and-black Cerachrom insert debuted on the 116710BLNR in 2013, a single-piece ceramic bezel in two colors had never been done. Rolex builds it as one component and chemically alters half of it to shift from blue to black, so the color break is baked into the ceramic, not painted on. That bezel will not fade or scratch. Movement-wise, the 3285 inside this reference is the big upgrade over the older 116710BLNR's caliber 3186: roughly 70 hours of reserve versus about 48, the Chronergy escapement, and stronger antimagnetic performance. On the wrist, the case is 40mm with 20mm lugs and wears like a proper tool watch, not a dress piece. If you are choosing between the two bracelets, the Oyster is the sportier, more robust feel and the Jubilee is dressier and more supple; the reference number is identical, so buy the wrist feel you actually want. When authenticating, check that the card, warranty date, and serial line up, confirm the bezel color transition is crisp, and make sure the movement is a 3285 and not a swapped older caliber. On a genuine current example the Chromalight lume glows blue and the rehaut engraving is clean.
