When it comes to modern luxury horology, few debates are as passionately contested as the battle of the bezels. In the red corner, we have the legendary Rolex GMT-Master II “Pepsi.” In the blue and black corner, the sleek and contemporary “Batgirl.”
While both belong to the esteemed 126710 generation and share the sophisticated five-link Jubilee bracelet, they project entirely different personalities on the wrist. As we navigate the luxury watch market in 2026, which of these Oystersteel titans deserves the top spot in your collection? Let’s break down the details.
The Heritage Heavyweight: GMT-Master II “Pepsi” (Ref. 126710BLRO)
The “Pepsi” is the undisputed patriarch of the GMT family. Tracing its lineage back to the original 1954 model designed for Pan American World Airways pilots, the red and blue colorway isn’t just an aesthetic choice; it’s a piece of aviation history.
When Rolex brought the Pepsi back in Oystersteel on a Jubilee bracelet in 2018, it created a waitlist phenomenon that continues to endure.
The Bezel: The bi-color red and blue Cerachrom bezel is notoriously difficult to manufacture. Rolex has to fire the ceramic to create the red half first, then chemically treat the other half before firing it again to turn it blue. This results in subtle, unique color shifts depending on the lighting.
The Vibe: Classic, unmistakable, and undeniably Rolex. The Pepsi is for the purist who wants their wristwear to tell a story of mid-century jet-setting glamour.
See It in Action: Still photos can only capture so much of the Pepsi’s charm. The true magic of the red and blue Cerachrom bezel lies in how it interacts with natural light. Check out our quick wrist roll below to see exactly how the 126710BLRO commands attention in motion, and notice the brilliant light play across the five-link Jubilee bracelet.
The Modern Masterpiece: GMT-Master II “Batgirl” (Ref. 126710BLNR)
While the Pepsi looks to the past, the “Batgirl” represents the modern era of the GMT-Master II. Born from the “Batman” (which originally debuted on the Oyster bracelet), the Batgirl emerged when Rolex updated the blue and black bezel model with the Caliber 3285 movement and paired it with the dressier Jubilee bracelet.
The Bezel: The black and blue Cerachrom insert offers a more subdued, versatile contrast compared to the Pepsi. The black seamlessly transitions into the dial, while the blue provides a striking pop of color that pairs perfectly with a navy suit or casual weekend wear.
The Vibe: Stealthy, contemporary, and incredibly versatile. The Batgirl is the choice for collectors who want a high-functioning travel watch that flies slightly more under the radar but still commands respect in horological circles.
See It in Action: To fully appreciate the stealthy elegance of the Batgirl, you need to see it on the wrist. In the short clip below, watch how the seamless transition between the black and blue ceramic bezel creates a dynamic, modern profile that shifts beautifully as it catches the light.

Under the Hood: A Perfect Tie
Mechanically, the 2026 playing field is perfectly level. Both the Batgirl and the Pepsi are powered by Rolex’s superlative Caliber 3285 movement.
Power Reserve: 70 hours, meaning you can take it off on Friday evening and it will still be ticking on Monday morning.
Technology: Equipped with the highly efficient Chronergy escapement and a blue Parachrom hairspring, making both watches highly resistant to magnetic fields and temperature variations.
Precision: Superlative Chronometer certified, guaranteeing an accuracy of -2/+2 seconds per day.
The Jubilee Factor: Why the Bracelet Matters
Historically, the GMT-Master was a pure tool watch, firmly married to the sporty, three-link Oyster bracelet. The reintroduction of the five-link Jubilee bracelet to the modern steel GMT lineup was a masterstroke by Rolex.
The Jubilee elevates the 126710 references from utilitarian travel tools to luxury statement pieces. It catches the light brilliantly, drapes over the wrist with unmatched comfort, and completely changes the center of gravity of the watch. Whether you choose the Batgirl or the Pepsi, the Jubilee bracelet ensures the watch slides effortlessly under a cuff while standing out in a crowded room.
The 2026 Verdict: Which Should You Choose?
In the current luxury market, both models hold their value exceptionally well, acting as both reliable timekeepers and solid asset allocations.
If you are a traditionalist who values heritage and the instantly recognizable “golden era” of Rolex design, the Pepsi remains the ultimate grail. However, if your wardrobe leans modern and you prefer a cooler, more contemporary color palette that transitions seamlessly from the boardroom to the departure lounge, the Batgirl is the undisputed winner.
Whichever side of the debate you fall on, securing one of these Jubilee icons is a milestone for any collector.
