In recent years, two models have captured the imagination of collectors and enthusiasts around the world: the GMT-Master II “Pepsi” (ref. 126710BLRO) and the GMT-Master II “Batman” (ref. 116710BLNR).

Both timepieces represent milestones in Rolex’s technical mastery and aesthetic evolution, yet they tell different stories-one grounded in history and nostalgia, the other in modern innovation and contemporary cool. As we look at them side by side, we not only see a comparison of design and mechanics but also a reflection of Rolex’s unique ability to bridge past and present, heritage and progress.

The Rolex GMT-Master II “Pepsi”

In 2018, Rolex unveiled what would become one of its most celebrated modern creations-the GMT-Master II “Pepsi” in stainless steel, reference 126710BLRO. Its debut sent shockwaves through the imitation watches community. For years, collectors had pleaded for a steel version of the beloved red-and-blue bezel, a design first seen on the original GMT-Master in 1955.

Until that point, the “Pepsi” bezel had been reserved for precious-metal versions, particularly in white gold. So when Rolex finally released it in Oystersteel (stainless steel), the response was electric. Here was a watch that blended modern Rolex engineering with one of the most recognizable color combinations in horological history.

The “Pepsi” name, of course, comes from its vivid red and blue Cerachrom bezel-colors that once served a practical function for airline pilots. The red half denoted daylight hours, and the blue half represented night, making it easy to track two time zones at a glance. For modern wearers, however, these colors have come to symbolize more than utility-they evoke a sense of adventure, of crossing boundaries, of flight and freedom.

Rolex paired the 126710BLRO with a Jubilee bracelet, a choice that divided opinions among enthusiasts. The five-link bracelet, traditionally seen as more elegant and dress-oriented, gave the “Pepsi” a refined aesthetic that contrasted with its sporty origins. Some longed for the robustness of the three-link Oyster bracelet, which had accompanied previous GMT models. Yet in retrospect, the decision seems deliberate-Rolex wanted to distinguish the new steel “Pepsi” from its white gold predecessor and to celebrate its reintroduction with a touch of classic sophistication.

Beneath its surface, the “Pepsi” was powered by Rolex’s new-generation Caliber 3285 movement, featuring improved precision, a longer 70-hour power reserve, and enhanced resistance to shocks and magnetic fields. It was a masterpiece of mechanical engineering concealed beneath the familiar design of an icon.

The Rolex GMT-Master II “Batman”

Five years before the rebirth of the steel “Pepsi,” Rolex had already redefined modern watchmaking with another colorful creation-the GMT-Master II “Batman,” reference 116710BLNR. When it debuted in 2013, the “Batman” was groundbreaking for a simple reason: it was the first Rolex to feature a two-tone Cerachrom ceramic bezel.

For years, Rolex had publicly stated that creating a dual-colored ceramic bezel was impossible. Ceramic, while extremely durable, was notoriously difficult to manipulate in multiple colors. Yet, true to its nature, Rolex solved the problem through years of research and innovation. The “Batman’s” black-and-blue bezel-subtle, modern, and bold-became an instant success.

Collectors adored its contemporary aesthetic. The color combination gave the watch a sleek, stealthy look that appealed to a new generation of enthusiasts who wanted a Rolex that felt both classic and forward-thinking. It was also highly versatile-the “Batman” looked equally at home with a suit as it did with a T-shirt.

The “Batman” came fitted exclusively with an Oyster bracelet, which gave it a sportier and more rugged profile compared to the Jubilee-equipped “Pepsi.” Its movement, the Caliber 3186, was an earlier generation than the 3285 found in the “Pepsi,” but still a robust, chronometer-certified engine that upheld Rolex’s reputation for precision and reliability.

The “Batman” also carried a certain quiet strength-it wasn’t just a colorful fake luxury watches; it was a technological triumph, a demonstration of Rolex’s ability to push material science forward while maintaining aesthetic harmony.

Comparing Two Legends: Design, Mechanics, and Meaning

When placed side by side, the “Pepsi” and the “Batman” reveal how Rolex has mastered the art of evolution rather than revolution. The differences are subtle yet significant, the result of a brand that values refinement over radical change.

Design:
Both watches share the same 40mm Oyster case, screw-down crown, and black “Maxi” dial with Chromalight-filled hour markers. Yet, their personalities couldn’t be more distinct. The “Pepsi” is vibrant and nostalgic-its colors echo the golden age of aviation and Rolex’s pioneering spirit. The “Batman,” on the other hand, is cool and contemporary-its black and blue hues mirror the modern traveler’s aesthetic, understated yet unmistakably bold.

Bracelet:
The bracelet choice plays a key role in defining each model’s character. The “Batman” wears its Oyster bracelet like a badge of sportiness, a reminder of the GMT’s tool-watch origins. The “Pepsi,” on its Jubilee bracelet, feels slightly more elegant, perhaps even sentimental-a tribute to Rolex’s mid-century legacy.

Movement:
Mechanically, the newer “Pepsi” (126710BLRO) holds the advantage, boasting the Caliber 3285 with its improved Chronergy escapement and 70-hour power reserve. The “Batman” (116710BLNR), though slightly older, is no less dependable, powered by the tried-and-tested Caliber 3186.

But perhaps the most interesting comparison lies not in their specifications, but in what they represent. The “Batman” marked a turning point for Rolex innovation-it broke the barrier of material limitations and brought a new color language to the GMT line. The “Pepsi,” by contrast, marked a return to tradition-it reconnected modern Rolex enthusiasts with the brand’s roots in aviation and exploration.

The GMT-Master was originally conceived in the 1950s for Pan Am pilots navigating the dawn of intercontinental flight. Its defining feature-the ability to track multiple time zones-reflected a world becoming increasingly connected. Decades later, that same function feels more symbolic than ever.

When you look at a “Pepsi” or a “Batman” today, you’re not just seeing two time zones-you’re seeing the convergence of eras. One hand points to the present, the other to history. The red and blue bezel reminds us of Rolex’s pioneering past; the black and blue one whispers of its forward momentum.

In a way, these top replica watches embody two sides of modern identity: nostalgia and progress. The “Pepsi” appeals to those who cherish heritage and the romanticism of early air travel. The “Batman” speaks to those who live in the digital age-fast-paced, connected, and global. Both remind us that, despite the changing world, craftsmanship and precision never go out of style.

The “Pepsi,” with its bright bezel, feels like sunlight breaking through the clouds-a symbol of optimism, of color, of history reborn. The “Batman,” with its darker tones, evokes night flights and city skylines-a vision of the modern traveler navigating a world of endless horizons.

The desirability of both models is undeniable. Waiting lists stretch for years, and pre-owned prices often exceed retail. But beyond their scarcity lies a deeper truth: people want these watches because they mean something.

They represent achievement, craftsmanship, and continuity. They connect their owners to Rolex’s enduring pursuit of perfection-a pursuit that has remained unchanged for more than a century. Whether you prefer the nostalgic warmth of the “Pepsi” or the sleek sophistication of the “Batman,” both models capture the essence of Rolex’s magic: evolution without compromise.

The GMT-Master II “Pepsi” and “Batman” are not rivals-they are reflections of each other, two expressions of the same enduring philosophy. One celebrates the past, the other embraces the future. Together, they tell a complete story of Rolex’s mastery: its respect for tradition, its commitment to innovation, and its unshakable grasp of what makes time meaningful.
