Pepsi vs. Batman: Choosing Your GMT-Master II

We buy and sell both of these every week at our counter on 19 West 47th Street, so this is not a magazine comparison written from a press kit. This is how the two watches actually behave when a real buyer is standing in front of us deciding which one goes home, and how they behave when that same buyer walks back in two years later wanting to sell. The Rolex GMT-Master II "Pepsi" 126710BLRO and the "Batman" 126710BLNR are the two steel travel Rolexes most people cross-shop, they share the same case, the same movement, and the same 100 meter water resistance, and yet they sit in very different places on the price sheet. Here is the honest breakdown.

Same platform, two personalities

Both watches are the current-generation 40mm GMT-Master II in Oystersteel, both run the caliber 3285 automatic with a 70-hour power reserve, Chronergy escapement, and blue Parachrom hairspring, and both carry a bidirectional 24-hour Cerachrom ceramic bezel with an independently jumping local hour hand for true dual-time-zone travel. Screw-down Triplock crown, 100 meters of water resistance. Mechanically they are the same watch. What separates them is color and, more than most buyers expect, bracelet.

126710BLRO Pepsi: red and blue ceramic bezel, black dial. Introduced at Baselworld 2018. This is the reference that revived the classic red-and-blue GMT look in modern ceramic on a steel case, and it is the one with the deepest emotional pull. Pilots wore Pepsi bezels in the 1950s and 1960s. Collectors know that history, and it shows up in the price.

126710BLNR Batman: blue and black ceramic bezel, black dial, blue GMT hand. The blue-and-black ceramic bezel first arrived on the earlier 116710BLNR in 2013, and the updated 126710BLNR with the caliber 3285 landed in 2019. The nickname stuck because the two-tone blue-black reads like the character's color scheme in most light, and goes nearly all-black indoors.

The bracelet question is the real decision

This is where most first-time buyers get tripped up, so read this part twice.

The Pepsi 126710BLRO launched in 2018 on the five-link Jubilee bracelet only. That was the sole factory option for three years. In 2021 Rolex added the three-link Oyster bracelet as an alternative. So a Pepsi can come either way, and the bracelet materially changes the character of the watch. Jubilee is dressier, more articulated on the wrist, and closer to the refined look of the original 1950s GMT. Oyster is sportier and more tool-like. Both are Oystersteel with the Oysterlock safety clasp and Easylink 5mm comfort extension.

The Batman 126710BLNR comes two ways from the factory, and the nicknames get confusing:

126710BLNR-0002 is the Batman on the Jubilee bracelet. The Jubilee version picked up its own nickname, "Batgirl," early on.
126710BLNR-0003 is the Batman on the Oyster bracelet.

So "Batman on Jubilee" and "Batgirl" are the same watch. When someone quotes you a Batgirl price, they are quoting the Jubilee-braceleted BLNR. Keep that straight, because on the buy and sell side the bracelet is worth real money.

Dial and bezel contrast in the metal

The dial is identical black on both, so the bezel does all the talking. The Pepsi's red-and-blue split is high-contrast and loud in a good way. It reads instantly across a room and photographs bright. The Batman's blue-and-black is quieter. In direct sun the blue pops, and under indoor light the whole bezel collapses toward black and the watch becomes a stealthier object with a single blue GMT hand as the only tell. If you want the watch to be a statement, the Pepsi does that. If you want a GMT that disappears under a cuff and only rewards the person actually looking at it, the Batman is the more versatile daily piece. We see plenty of buyers who own one and come back for the other precisely because they scratch different itches.

Market premiums: what these actually cost right now

Here is where the two references separate hard, and where our buy side matters.

On April 14, 2026, at Watches and Wonders Geneva, Rolex discontinued the steel ceramic Pepsi 126710BLRO along with the white gold 126719BLRO. Discontinuation did exactly what discontinuation always does to a watch with this much history: it lit the secondary market. Pepsi examples that were trading in the low 20s jumped through Q1 and into the spring. As of this July, most steel 126710BLRO pieces are changing hands in roughly the $22,000 to $30,000 range depending on condition, bracelet, and whether the full set with box, papers, and tags is present. Unworn 2026-dated examples with everything intact have been pushing toward $40,000. The Jubilee Pepsi generally carries a slight premium over the Oyster Pepsi, but with this reference the bigger driver right now is simply that it is discontinued and everyone knows it.

The Batman 126710BLNR is a different story because it is still, as of this writing, a current-production reference on the price list. Rolex retail after the January 2026 adjustment sits around $11,800 to $12,000, but authorized dealer availability is effectively zero for a walk-in buyer, which is why the secondary market runs above retail. Pre-owned Batman examples are trading roughly in the $16,000 to $20,000+ band. The Jubilee "Batgirl" typically sits a touch above the Oyster Batman, driven by collector preference for the five-link bracelet. Batman pricing has also been calmer than Pepsi pricing: after the broad market peak in early 2022, the BLNR gave back a chunk of froth and then flattened out, holding fairly steady across 2023 and 2024 rather than swinging.

Put simply: as of today the Pepsi is the more expensive watch and the more volatile one, and the Batman is the more affordable entry into a ceramic steel GMT with more stable, more predictable pricing.

Resale behavior: how they act when you sell

We write the checks, so this is the part we care about most.

The Pepsi behaves like a trophy. Its price moves with sentiment and news. The 2026 discontinuation is a textbook example: nothing about the watch changed, but the secondary price moved several thousand dollars on the announcement alone. That cuts both ways. If you buy a Pepsi and the market runs, you look brilliant. If you buy at a discontinuation-fueled peak and sentiment cools, you can give some back. For a seller, a full-set Pepsi with box and papers is one of the easiest steel Rolexes to move quickly, and it commands the strongest offers we make on a modern GMT.

The Batman behaves like a workhorse with a floor. Because it is still in production and made in large numbers, it does not spike the way the Pepsi does, but it also does not fall out of bed. That stability is exactly what a lot of buyers want: a watch they can wear hard, enjoy, and sell in a couple of years without a nasty surprise. On the buy side, a clean Batman is a watch we can always price with confidence because the comparable sales are thick and current.

One rule holds for both: full set wins. Box, papers, hang tags, and an unpolished case with sharp lugs move our offer up meaningfully versus a watch-only piece with soft edges. If you still have the card and the accessories, keep them together.

So which one should you buy

If you want the historic, high-contrast, higher-ceiling watch and you are comfortable with a price that moves on news, buy the Pepsi 126710BLRO, and if you can find one on the bracelet you actually want, do not overthink Jubilee versus Oyster because both are correct factory configurations. If you want the more affordable, more discreet, more stable everyday GMT, buy the Batman 126710BLNR, and decide Jubilee ("Batgirl," the -0002) versus Oyster (the -0003) based on whether you lean dressy or sporty. There is no wrong answer here, only the right answer for your wrist and your budget.

Buy it, sell it, or trade it with us

We keep both references in stock and in motion because they are two of the most traded steel Rolexes in the market. Buying your first ceramic GMT, upgrading from a Batman to a Pepsi, or sitting on a full-set piece you are ready to cash out: we can price it accurately the same day, because we quote from the same numbers we use to write checks.

Call Ultimate Diamond or stop by the counter at 19 West 47th Street in New York City. We have been buying and selling watches on this block since 1959, and we would rather look at your Pepsi or Batman in person and give you a real number than have you guess from a chart.
