Rolex GMT-Master II Guide: Pepsi, Batman & Root Beer Explained

Published September 10, 2026 · Last updated October 20, 2026 · By Lume Wrist Watches

The Rolex GMT-Master II stands as a titan in the world of luxury travel watches, revered for its robust functionality and iconic dual-color bezels. This guide delves into the most celebrated iterations – the Pepsi, Batman, and Root Beer – offering an expert perspective on their distinct characteristics, historical significance, and current market standing to inform your acquisition.

Why the Rolex GMT-Master II Matters: A Beacon of Global Travel

The GMT-Master II is more than just a timepiece; it's a horological instrument designed for the demands of intercontinental travel, conceived originally for airline pilots. Its ability to display three time zones simultaneously – two concurrently – has made it indispensable for jet-setters and professionals alike. The collection's iconic bi-color bezels, particularly the red and blue 'Pepsi', the blue and black 'Batman', and the brown and black 'Root Beer', are not merely aesthetic choices but functional indicators, distinguishing day from night in a second time zone. This blend of precision engineering, enduring design, and practical utility positions the GMT-Master II as a cornerstone of Rolex’s professional watch lineup, appealing to collectors and discerning individuals who value both form and function.

Brand History and Defining Milestones of the GMT-Master II

The story of the GMT-Master II begins with its predecessor, the original GMT-Master, which Rolex developed in close collaboration with Pan American World Airways (Pan Am) in the early 1950s. Pan Am pilots required a reliable watch to track multiple time zones during their long-haul flights.

• 1955: Rolex introduces the GMT-Master ref. 6542. This pioneering model featured a fourth hand that completed a rotation every 24 hours, paired with a rotating 24-hour bezel. The original bezel was made of Plexiglas with radium luminous material beneath. The famous red and blue "Pepsi" bezel, denoting day and night, debuted with this reference.
• 1959: The GMT-Master ref. 1675 arrives, marking a significant evolution. It introduced crown guards, a larger case, and a redesigned bezel that transitioned from Bakelite to aluminum, offering increased durability. This reference enjoyed a long production run, seeing various dial and hand variations.
• 1982: The GMT-Master II ref. 16760, nicknamed "Fat Lady" or "Sophia Loren" due to its thicker case, is launched. This model was revolutionary for allowing the independent adjustment of the 24-hour hand, meaning the wearer could track a third time zone simultaneously without disturbing the main time display. It debuted with a red and black bezel, the "Coke" bezel. This marked the official birth of the GMT-Master II series, which coexisted with the original GMT-Master for a period.
• 1989: The GMT-Master II ref. 16710 replaces the "Fat Lady," featuring a slimmer profile and new caliber 3185. It offered the "Pepsi" (red/blue), "Coke" (red/black), and all-black bezel options.
• 2005: Rolex ushers in the ceramic era with the GMT-Master II ref. 116710LN. This model introduced the virtually scratchproof Cerachrom bezel, a new bracelet with Easylink extension, and the improved caliber 3186. Initially, only an all-black ceramic bezel was available.
• 2013: The iconic GMT-Master II ref. 116710BLNR, the "Batman," makes its debut, featuring the innovative blue and black Cerachrom bezel – a technical feat previously deemed impossible for Rolex due to the challenge of creating a perfect two-tone ceramic.
• 2014: The beloved "Pepsi" bezel returns in ceramic for the GMT-Master II. Initially offered exclusively on the white gold ref. 116719BLRO, it quickly became one of the most sought-after watches.
• 2018: A pivotal year for the GMT-Master II. Rolex introduces the "Root Beer" in Cerachrom with the ref. 126711CHNR (Everose gold and Oystersteel) and ref. 126715CHNR (full Everose gold), marking the first two-tone ceramic bezel in brown and black. Crucially, the stainless steel "Pepsi" ref. 126710BLRO is released, but exclusively on the Jubilee bracelet, moving away from the Oyster bracelet found on the white gold version. The "Batman" also received an update to ref. 126710BLNR, transitioning to the Jubilee bracelet.
• 2019: Rolex continues to refine the collection, including the "Batman" and "Pepsi" references, solidifying their place as modern icons, now primarily offered on the five-link Jubilee bracelet, enhancing their comfort and distinctive aesthetic. A new caliber, 3285, is also introduced across the line.

Every Current GMT-Master II Collection Explained, with Signature References

The modern GMT-Master II collection showcases Rolex's mastery of materials and design, offering a compelling range of options, each defined by its distinctive Cerachrom bezel. The common thread among these contemporary models is the 40mm Oyster case, the bidirectional rotatable 24-hour graduated bezel, and the choice between an Oyster or Jubilee bracelet, varying by reference.

The "Pepsi" (Red and Blue Bezel)

The "Pepsi" is arguably the most recognizable and historically significant GMT-Master II. Its red and blue bezel harks back to the original 1955 GMT-Master, instantly conjuring images of aviation and global adventure. In its modern ceramic form, the red half signifies daytime hours, and the blue half signifies nighttime hours in the second time zone.

• Reference 126710BLRO (Oystersteel): This is the stainless steel version of the modern ceramic Pepsi, introduced in 2018. It comes exclusively on a five-link Jubilee bracelet, a departure from earlier stainless steel GMT-Masters. The combination of Oystersteel and the vibrant ceramic bezel makes it a highly coveted piece. Its 40mm Oyster case houses the advanced Caliber 3285.
• Reference 116719BLRO (18K White Gold): Introduced in 2014, this was the first ceramic Pepsi and was initially exclusive to 18K white gold. It featured the Oyster bracelet. While the steel version gained popularity, the white gold offers a more understated luxury with the same iconic bezel.

The "Batman" (Blue and Black Bezel)

The "Batman" is a modern icon, recognized by its striking blue and black Cerachrom bezel. Introduced in 2013 as a world-first bi-color ceramic for Rolex, it quickly gained immense popularity. The black portion of the bezel indicates nighttime hours, while the blue denotes daytime, offering a sophisticated and slightly more subdued alternative to the Pepsi.

• Reference 126710BLNR (Oystersteel): The current stainless steel Batman model, updated in 2019, features the Jubilee bracelet, much like its Pepsi counterpart. This iteration built upon the legacy of the original 116710BLNR, retaining the same mesmerizing blue and black bezel but enhancing wearability with the more flexible Jubilee. This reference also houses the Caliber 3285.
• Reference 116710BLNR (Oystersteel): The original "Batman," introduced in 2013, came exclusively on the Oyster bracelet. This reference, with its Caliber 3186, remains highly sought after on the pre-owned market due to its iconic status as the first blue and black Cerachrom GMT-Master II.

The "Root Beer" (Brown and Black Bezel)

The "Root Beer" GMT-Master II is a revival of a vintage aesthetic, updated with modern materials. Its brown and black Cerachrom bezel, combined with Everose gold, offers a warm, distinctive, and luxurious appeal. The brown often signifies the daylight hours, transitioning to black for the night.

• Reference 126711CHNR (Oystersteel and Everose Gold – Rolesor): Introduced in 2018, this two-tone "Root Beer" combines Oystersteel for the case and outer links of the Oyster bracelet with 18K Everose gold for the crown, bezel, and center links. This blend of robustness and luxury is a signature of Rolex's Rolesor watches. The chocolate and black bezel perfectly complements the Everose gold accents, creating a truly unique presence.
• Reference 126715CHNR (18K Everose Gold): Also launched in 2018, this full 18K Everose gold version of the "Root Beer" represents the pinnacle of luxury within the collection. Paired with the same brown and black bezel, it offers a substantial feel and an unparalleled warmth, catering to those who desire the ultimate in precious metal expression.

Each of these models, whether steel or gold, on Oyster or Jubilee, embodies the spirit of global exploration and Rolex's unwavering commitment to excellence. For other notable Rolex sports watches, consider our Rolex Submariner Reference Guide: Models, History & Buying Advice.

Movements and In-House Calibers Used Across the Range

Rolex’s reputation for precision and reliability is inextricably linked to its in-house movements. The GMT-Master II has been powered by a lineage of highly sophisticated self-winding mechanical calibers, all developed and manufactured entirely by Rolex.

• Caliber 3185 (1989-2005): This movement powered the ref. 16710. It was a certified Swiss chronometer (COSC) with a 48-hour power reserve and featured the independently adjustable 24-hour hand, a hallmark of the GMT-Master II.
• Caliber 3186 (2005-2019 for specific references): An evolution of the 3185, this caliber was introduced with the ceramic bezel models (e.g., ref. 116710LN, 116710BLNR, and 116719BLRO). It maintained the 48-hour power reserve but incorporated Rolex's patented Parachrom hairspring, offering enhanced resistance to shocks and temperature variations for improved accuracy and stability. Its jump-hour mechanism for the local time hand was also refined, making the "jump" more precise.
• Caliber 3285 (2018-Present): The latest generation movement, introduced with the 1267xx references (e.g., 126710BLRO, 126710BLNR, 126711CHNR). This movement represents a significant leap forward, boasting 10 new patents. Its key innovation is the Chronergy escapement, which improves energy efficiency by 15%, extending the power reserve to approximately 70 hours. This "superlative chronometer" also features a larger mainspring barrel and an optimized gear train, all contributing to superior precision and reliability. The Caliber 3285 is Rolex's current standard for the GMT-Master II, reflecting their continuous pursuit of horological perfection.

All Rolex movements undergo rigorous testing by COSC and then further in-house testing by Rolex to ensure they meet their "Superlative Chronometer" standard of -2/+2 seconds per day accuracy after casing – exceeding industry norms.

Price Tiers Today: Entry, Core and Grail, with Realistic Ranges

Acquiring a Rolex GMT-Master II involves navigating a complex market, particularly for popular references. Prices are highly dependent on condition, age, complete set (box and papers), and current market demand. The ranges below are approximate observations for the pre-owned market as of 2026.

What to Check Before Buying Pre-Owned from this Maison

Buying a pre-owned Rolex GMT-Master II, especially models like the Pepsi, Batman, or Root Beer, requires careful scrutiny to ensure authenticity and value. Lume Wrist Watches prides itself on our inspection process process, but here's what discerning buyers should generally consider:

• Authenticity: This is paramount. Verify all engravings, serial numbers, and hallmarks. Ensure the movement is original to the watch and hasn't been replaced with non-Rolex parts. Bezel colors, luminosity of hands and markers, and dial fonts are crucial indicators. Ensure the Cerachrom bezel colors are distinct and not faded or improperly colored, as these are complex to produce.
• Condition: Examine the case, bezel, crystal, and bracelet for scratches, dents, or signs of over-polishing. Over-polishing can erode the case's original lines and reduce its value. The ceramic bezel inserts should be free of cracks or significant chips. Assess the tightness of the bracelet; excessive stretch can be costly to repair.
• Movement Health: Request service history if available. A watch that hasn't been serviced in many years may require immediate attention, which can add significant cost. Listen for a smooth rotor winding. Ensure all functions, particularly the independent GMT hand, operate correctly.
• Originality: Confirm that the dial, hands, bezel insert, and bracelet are original to the reference and period. "Service dials" or non-original parts can affect value. For example, ensuring a ref. 116710BLNR has an Oyster bracelet and a 126710BLNR has a Jubilee is critical.
• These documents verify the watch's serial number, purchase date, and authenticity from the point of sale.
• Source: Always buy from a reputable and authenticated dealer like Lume Wrist Watches. Our concierge sourcing service ensures you receive exactly what you expect.

Frequently Asked Questions

### What is the difference between the Rolex GMT-Master and GMT-Master II? The primary difference lies in the movement's functionality. The GMT-Master II allows the wearer to independently adjust the local hour hand without stopping the watch or affecting the 24-hour hand, enabling the display of a third time zone. The original GMT-Master's 24-hour hand was synchronized with the local hour hand, allowing only two time zones to be read.

### Why are the Rolex Pepsi, Batman, and Root Beer so popular and sought-after? Their popularity stems from a combination of factors: historical significance (Pepsi), groundbreaking technical achievement (Batman's first two-tone ceramic), unique aesthetic appeal (Root Beer's warmth), strong brand recognition, robust movements, and perceived scarcity. These factors, combined with Rolex's market strategy, drive high demand and often command premiums on the secondary market.

### Can I put an Oyster bracelet on a modern stainless steel GMT-Master II Pepsi (126710BLRO)? While technically possible for some references to swap bracelets, the current stainless steel GMT-Master II Pepsi (126710BLRO) is factory-issued exclusively on the Jubilee bracelet. The stainless steel Batman (126710BLNR) also comes solely on Jubilee. For the most part, Rolex designs its bracelets to fit specific references, and altering them might affect authenticity or fit, although some enthusiasts do pursue these modifications.

### How does the GMT-Master II bezel work to track multiple time zones? The bidirectional rotatable 24-hour graduated bezel works in conjunction with the dedicated 24-hour hand. To read a second time zone, align the 24-hour hand with the time on the bezel for that zone. To track a third, you can rotate the bezel by the difference in hours from your home time (e.g., rotate 3 clicks clockwise for 3 hours ahead) and read the third time zone directly from the bezel scale using the 24-hour hand.

### What does "Rolesor" mean in the context of the GMT-Master II Root Beer? "Rolesor" is Rolex's term for watches that combine Oystersteel and gold. In the case of the "Root Beer" ref. 126711CHNR, it refers to the watch being crafted from a combination of Oystersteel and 18K Everose gold. The case and outer links of the bracelet are steel, while the bezel, winding crown, and center links of the bracelet are Everose gold.

### What is the typical power reserve of a modern GMT-Master II? Modern Rolex GMT-Master II models featuring the Caliber 3285 (references 1267xx) boast an impressive power reserve of approximately 70 hours. Older models with the Caliber 3186 typically offered around 48 hours of power reserve.
