Every Rolex sports watch has a nickname, but few have two. The GMT-Master II 126710BLNR is the "Batman" on its Oyster bracelet and the "Batgirl" on its Jubilee — one reference, two personalities, and a fan base that treats the black-and-blue bezel like a flag. It's the most accessible steel GMT in current production and one of the most faked. Here's the full picture: the history, the market, and the details counterfeits consistently get wrong.

A brief history of the black-and-blue bezel

The Batman story starts in 2013, when Rolex launched the 116710BLNR — the first GMT-Master II with a two-color Cerachrom ceramic bezel, on the sporty three-link Oyster bracelet. It was an instant hit. In 2019, Rolex replaced it with the 126710BLNR, switching to the five-link Jubilee bracelet and upgrading to the calibre 3285 with a 70-hour power reserve. Collectors, missing the Oyster look, dubbed the Jubilee version "Batgirl."

Then in 2021, Rolex did something unusual: it brought back the Oyster bracelet as a factory option on the same 126710BLNR reference. So today, one reference number covers both bracelets — Batman (Oyster) and Batgirl (Jubilee) — and buyers choose their personality at the counter. Assuming they can get to the counter; like all steel Rolex sports watches, this one lives on waitlists.

The watch itself

The 126710BLNR is a 40mm Oystersteel GMT-Master II: black dial, bidirectional 24-hour Cerachrom bezel split between black (night hours) and blue (day hours), and the signature blue 24-hour hand. The calibre 3285 drives an independently adjustable local hour hand — the defining GMT-Master II function — with Rolex's Chronergy escapement and Parachrom hairspring. Water resistance is 100 meters, and the bracelet (whichever you choose) carries the Easylink 5mm comfort extension.

The bezel deserves a note: Rolex's Cerachrom process produces the two colors in a single ceramic piece, with a razor-sharp transition at the 6 and 18 markers. That crisp color split is one of the hardest things in the watch to manufacture — and one of the first things fakes get wrong.

Oyster vs. Jubilee: does it matter for value?

Both bracelets are factory-correct on the 126710BLNR, so neither is "wrong." But the market has opinions:

• The Jubilee ("Batgirl") version is the one Rolex launched first on this reference, and it remains the more common configuration. It dresses the watch up slightly — the five-link bracelet catches light in a way the Oyster doesn't.

• The Oyster ("Batman") version, reintroduced in 2021, leans sportier and, in most markets, commands a small premium on the secondary market — buyers tend to prefer the tool-watch look, and fewer were made in the early years.

The gap is modest — typically a few hundred to around a thousand dollars on comparable examples — not a different price tier. Buy the bracelet you like; both are correct, and both will resell well. One practical note: bracelets are swappable by Rolex service, but a swapped bracelet without documentation can raise questions at resale. Factory-original configuration, matching the warranty card era, is always cleanest.

What it costs (as of late 2026)

Retail on the 126710BLNR is approximately $11,800–$12,000 depending on bracelet, after Rolex's periodic price adjustments. As with all steel sports Rolex, retail availability is the constraint — expect a waitlist measured in months to years at most authorized dealers.

Pre-owned, full-set examples in good condition typically trade between $18,000 and $21,000, with unworn 2026-dated pieces at the top end. (For context, dealer transaction data through mid-2026 put the average pre-owned BLNR around $19,700.) That's a substantial premium over retail, but notably steadier than the wilder swings of the Pepsi or the hype peaks of 2022 — the Batman's premium has been remarkably durable, which is exactly why dealers call it one of the safest buys in the catalog.

Market trajectory: why the Batman endures

The BLNR has never been the scarcest GMT or the flashiest, and that's its strength. The Pepsi (126710BLRO) gets the collector headlines — and its 2026 discontinuation only intensified that. The "Bruce Wayne" (126710GRNR, grey-black bezel) is the current darling. Through all of it, the Batman has held a steady premium with deep buyer demand at every price point. It's the GMT people actually wear daily: legible, versatile, and recognizable without shouting.

For a dealer, that steadiness is gold. A Batman bought right can be turned in days, in any market condition. Hype references spike and correct; the Batman just sells.

Spotting a fake: the details that matter

The 126710BLNR is one of the most counterfeited watches in the world, and modern fakes are good enough to fool a casual glance. The tells that still catch them:

• The bezel color split. Genuine Cerachrom has a perfectly crisp transition between blue and black at 6 and 18, with rich, deep color. Fakes often show a blurry or gradual transition, or blue that's too bright or too purple.

• The rehaut engraving. "ROLEX" repeated around the inner bezel ring, with the serial at 6 o'clock. On genuine pieces it's laser-crisp; on fakes it's often shallow or unevenly spaced.

• The GMT hand. The blue 24-hour hand should be a deep, even blue with a perfectly formed arrow tip. Fakes frequently get the shade or the tip geometry slightly off.

• The cyclops. The date magnifier should enlarge 2.5x with no distortion and sit perfectly centered over the date window. Weak magnification or off-center placement is a classic fake tell.

• The movement. A genuine 3285 is beautifully finished and beats at 28,800 vph with a smooth seconds sweep. Most fakes use a decorated generic movement — if a seller won't show the watch running, or the seconds hand stutters, walk away.

• The warranty card. Serial on the card must match the rehaut. Full stop.

None of these replaces professional authentication on a five-figure purchase — but together, they're how you avoid the obvious traps before you ever get to that step.

The bottom line

The Batman is the thinking person's steel Rolex: all of the GMT-Master II's capability, a design that works with everything, and a market position built on steady demand rather than hype cycles. Whether you take it on Oyster or Jubilee, you're buying the most liquid dual-time-zone watch on the planet.
