Rolex GMT-Master II “Batgirl” 40mm Black Dial Black & Blue Cerachrom Bezel Jubilee Bracelet 126710BLNR | 2024 Full Set

The Dark Knight of the GMT-Master Family — Batgirl on Jubilee

The Rolex GMT-Master II 126710BLNR holds a distinction earned in the most unambiguous way possible: it is one of the most waitlisted, most discussed, and most consistently above-retail watches in the entire current Rolex catalog. Its nickname — “Batgirl” — has a specific and meaningful origin. When the predecessor reference 116710BLNR introduced the first-ever black and blue Cerachrom ceramic bezel to the GMT-Master II lineup at Baselworld 2013, collectors immediately dubbed it “Batman” for its dark knight color palette. When Rolex upgraded the reference to the 126710BLNR in 2019, it launched exclusively on the Jubilee bracelet — and for the first two years of its production run, from 2019 through 2021, the Jubilee was the only bracelet option available. The collector community immediately distinguished it from its Oyster-bracelet sibling with a new name: Batgirl — acknowledging that Rolex had handed the established Batman a more refined, more elegant counterpart. This 2024 full-set example in new condition represents the most current production of the reference, with all the refinements of the post-2019 generation and the most desirable bracelet configuration in the 126710BLNR family.

904L Oystersteel Case — The Definitive Modern GMT Profile

The 40mm Oyster case is crafted from Rolex’s proprietary 904L stainless steel — a high-performance, high-corrosion-resistant alloy that delivers a deeper, more reflective polish than the 316L steel used by most competing manufacturers. The case features sharp edges with a brushed finish on flat surfaces and a high polish finish on the sides, creating a dynamic interplay of textures that communicates both the watch’s professional tool-watch heritage and its refined aesthetic character. The monobloc middle case is fitted with a screw-down solid caseback and a screw-down Triplock triple-waterproofness crown — the same three-gasket crown system used on the Submariner — delivering water resistance to 100 meters and a level of environmental sealing that far exceeds what the vast majority of owners will ever put to the test. A scratch-resistant sapphire crystal with Cyclops magnifying lens protects the black dial and date window, and the case measures 12mm in thickness — slim enough to clear a shirt cuff comfortably while still conveying the substantial presence appropriate to a professional dual-timezone instrument.

The Black and Blue Cerachrom Bezel — “BLNR”: Bleu-Noir

The model designation suffix tells the full story: BLNR stands for Bleu-Noir — French for blue-black — the two-colour Cerachrom ceramic bezel that defines the reference and gives it both its nicknames. Producing a two-colour ceramic bezel insert requires manufacturing two separate pieces — one black, one blue — bonding them precisely at the midpoint, and then firing them together at extremely high temperatures to create a seamless, flawless single-piece insert with no visible joint, adhesive, or mechanical fastening anywhere along the colour transition line. The result is a bezel that is pure ceramic throughout, in two perfectly matched and permanently saturated colours that will never fade, scratch, or discolour regardless of UV exposure, saltwater contact, or decades of daily wear. The bezel’s 24-hour scale numerals and graduation marks are moulded directly into the ceramic surface and filled via Physical Vapour Deposition — etched into the material itself rather than applied on top, making them as permanent as the bezel. The bezel rotates bidirectionally — distinguishing the GMT-Master II from the unidirectional Submariner bezel — because for a travel complication, measuring elapsed time in either direction is equally useful. It clicks precisely through its 60-position rotation and locks securely between positions for accurate second time zone reading at a glance.

The Black Chromalight Dial with Blue GMT Hand

The black lacquered dial features applied white gold hour markers filled with Chromalight luminescent material — Rolex’s proprietary long-lasting luminescent compound that emits a distinctive, intense blue glow in darkness, significantly brighter and more sustained than standard Super-LumiNova. The matching Mercedes-style hands in steel are also Chromalight-filled, and the signature arrow-tipped 24-hour GMT hand is finished in blue — a deliberate design choice that ties the GMT hand directly to the blue half of the ceramic bezel, making it immediately visually distinguishable from the regular hour hand at a glance, even in low-light conditions. The blue GMT hand circles the dial once every 24 hours and is read against the 24-hour scale on the rotating bezel to display a reference or home time zone. The date is displayed at 3 o’clock beneath the Cyclops magnifying lens, and the Rolex-engraved rehaut runs the full inner circumference of the bezel, providing an additional layer of authentication detail visible only at close inspection. The blue GMT hand adds a pop of color while complementing the bezel’s iconic design, and the black lacquered dial is both functional and elegant, featuring Chromalight-filled markers and hands for optimal legibility in any lighting condition.

The GMT Complication — Three Time Zones Simultaneously

The GMT-Master II complication remains one of the most practically useful features in all of watchmaking. In addition to the conventional hour, minute, and seconds hands, the blue GMT hand displays a reference or home time zone by completing one full revolution every 24 hours while the local time is tracked by the standard hour hand. The local hour hand can be advanced or retarded by one-hour increments independently of the minute and seconds hands — meaning crossing a time zone requires nothing more than pulling the crown and rotating the hour hand forward or back, without stopping the movement, disrupting the seconds accuracy, or affecting the GMT hand’s reference time display. The result is a watch capable of displaying three time zones simultaneously: local time on the hour and minute hands, reference time on the GMT hand and bezel, and the date at 3 o’clock — covering the complete information needs of any international traveler with a single, instantaneous glance at the wrist.

The Five-Link Jubilee Bracelet — The Batgirl’s Defining Characteristic

The Jubilee bracelet is the single detail that distinguishes the Batgirl from the Batman, and for a meaningful segment of collectors it is also the reason they prefer the Batgirl. The five-piece-link Jubilee bracelet delivers a fluid, articulated wrist feel that the three-link Oyster bracelet cannot match — its smaller, more closely spaced links drape across the wrist with a softness and natural movement that makes it significantly more comfortable for extended wear, particularly through long-haul flights and full working days. The bracelet closes with a folding Oysterlock safety clasp and includes the Easylink 5mm comfort extension link for quick tool-free adjustment. When the 126710BLNR first launched in 2019, Rolex made a deliberate decision to pair it exclusively with the Jubilee — a configuration that has since become the most consistently requested in the reference. The Jubilee bracelet has historically been associated with the Rolex Pepsi GMT-Master since the earliest generations of the model in the 1950s, making its pairing with the Batgirl a nod to that heritage while delivering a distinctly contemporary result.

Powered by Caliber 3285 — Rolex’s Most Advanced GMT Movement

The 126710BLNR is powered by the Caliber 3285, the most technically advanced movement Rolex has ever produced for the GMT-Master II lineup. The Chronergy escapement — machined from nickel-phosphorus — delivers approximately 15% greater energy efficiency than a conventional Swiss lever escapement while providing outstanding resistance to magnetic fields. The blue Parachrom hairspring made from a proprietary zirconium-niobium alloy is virtually unaffected by temperature fluctuations, shocks, or magnetic interference, and Paraflex shock absorbers provide additional structural resilience. The movement runs on 31 jewels at 28,800 vibrations per hour, with a 70-hour power reserve — a significant increase from the 48 hours delivered by the previous generation. Stop-seconds for precise time setting is included, with the local hour hand adjustable independently of the minute and seconds hands via the crown’s rapid-setting mechanism. The movement carries Rolex’s Superlative Chronometer certification, regulated to an incredible +2/-2 seconds per day and a standard twice as exacting as standard COSC chronometer requirements.

Why This Reference Stands Out

The current retail price from Rolex after the January 2026 price adjustment sits around $11,800 to $12,000 for the 126710BLNR, but authorized dealer availability is effectively zero for most buyers, which is why secondary-market pricing runs consistently above retail. Secondary market data confirms the Batgirl trading between $16,000 and $20,000 for current full-set examples, making this $16,000 new-condition listing the most competitive entry point currently available for the reference. The Jubilee bracelet configuration commands collector preference among buyers who prioritize daily wearability and the historical GMT-on-Jubilee aesthetic, while the black-and-blue BLNR bezel gives this watch an instantly recognizable identity shared by no other reference in the GMT-Master II family. For the buyer who wants the most complete, most comfortable, and most historically connected expression of the current black-and-blue GMT-Master II, the Batgirl on Jubilee is the definitive answer — and this 2024 new full-set example is the ideal way to own it.
