I. The Spec Sheet: Rolex GMT-Master II 126710BLRO “Pepsi”

Let’s begin with the technical specifications that define the Rolex GMT-Master II 126710BLRO “Pepsi.” This timepiece features a 40mm Oyster case made of Rolex’s signature 904L stainless steel. Its automatic movement, the Caliber 3285, ensures precise timekeeping and boasts a power reserve of approximately 70 hours. The most striking feature, the bi-color bezel in red and blue, is crafted from Rolex’s patented Cerachrom ceramic material, rendering it virtually scratchproof and fade-resistant. These specifications not only contribute to the watch’s exceptional durability but also its timeless allure.


The Rolex GMT-Master II 126710BLRO “Pepsi” sets a high bar with its exceptional specifications. Its 40mm Oyster case, known for its robustness and corrosion resistance, is crafted from Rolex’s own 904L stainless steel. This specific steel type is not only durable but also highly resistant to wear and tear. The choice of steel ensures that the watch can withstand the test of time and maintain its luster for generations.


At the heart of the “Pepsi” beats the Caliber 3285, an automatic movement developed and manufactured by Rolex. This movement is renowned for its precision and reliability. It features a Parachrom hairspring that is resistant to magnetic fields and shocks, ensuring that the watch maintains its accuracy in various conditions. The Caliber 3285 also boasts a power reserve of approximately 70 hours, meaning you can set it aside for a weekend, and it will still keep ticking.


The most iconic element of the Rolex GMT-Master II 126710BLRO is undoubtedly its bi-color Cerachrom ceramic bezel. The choice of ceramic not only ensures the bezel’s resilience to scratches but also provides an exceptional, long-lasting vibrancy to the red and blue colors. This particular “Pepsi” bezel pays homage to the original GMT-Master from the 1950s and has become synonymous with the model.

II. Comparison of the Old and New Rolex GMT Master II Pepsi

To truly appreciate the GMT-Master II “Pepsi,” it’s essential to compare it to its predecessors. We’ll explore the evolution of this iconic watch, examining the key differences between vintage models and the modern 126710BLRO. From the transition from aluminum to ceramic bezels to improvements in movement and case materials, this section highlights the innovations that have propelled the “Pepsi” to new heights.

The evolution of the Rolex GMT-Master II “Pepsi” is a fascinating journey through horological history. The earlier models, such as the GMT-Master 1675, featured aluminum bezels with red and blue inserts. While these bezels were iconic, they were more susceptible to fading and scratching compared to the modern Cerachrom ceramic bezel of the 126710BLRO.

One of the most significant advancements is the transition to ceramic bezels. Rolex introduced the Cerachrom bezel in the GMT-Master II collection in the mid-2000s. This material is not only highly resistant to fading and scratching but also possesses a vibrant and enduring color scheme. The Cerachrom “Pepsi” bezel of the 126710BLRO pays homage to the original GMT-Master’s iconic look while incorporating modern materials and technology.

In terms of movement, the older GMT-Master models, including the GMT-Master 1675, were powered by Rolex’s Caliber 1575, a reliable workhorse movement. However, the newer GMT-Master II 126710BLRO boasts the advanced Caliber 3285, which offers enhanced accuracy, resistance to shocks and magnetic fields, and a longer power reserve. This technological evolution is a testament to Rolex’s commitment to pushing the boundaries of watchmaking excellence.

The case materials have also seen improvements over the years. Vintage GMT-Master models featured stainless steel cases, while the GMT-Master II 126710BLRO benefits from Rolex’s proprietary 904L stainless steel, known for its superior corrosion resistance. This upgrade ensures that the watch remains pristine, even in harsh conditions.

III. Rolex GMT Master II Pepsi vs. Root Beer

While the “Pepsi” is celebrated for its red and blue bezel, Rolex offers another enticing option—the GMT-Master II “Root Beer.” We’ll delve into the distinctions between these two iconic models, from their color schemes to their historical significance. Whether you prefer the classic “Pepsi” or the warm tones of the “Root Beer,” this section will help you make an informed choice.

The Rolex GMT-Master II “Root Beer” is a timepiece that exudes sophistication and warmth. Its bezel features a unique combination of brown and black, evoking the rich hues of a root beer float. This distinct color scheme sets it apart from the classic “Pepsi” bezel, which combines red and blue.

The “Root Beer” bezel was first introduced in the 1960s and has undergone several iterations over the years. Early models featured an aluminum bezel insert with brown and gold tones. In the 1980s, Rolex introduced the GMT-Master II “Root Beer” with a two-tone brown and gold bezel, often referred to as the “Nipple Dial” due to the raised hour markers on the dial. These vintage “Root Beer” models have become highly sought after by collectors.

In recent years, Rolex reintroduced the “Root Beer” bezel in the GMT-Master II collection, this time in Cerachrom ceramic. The modern “Root Beer” bezel retains the warm, earthy tones of its predecessors while benefiting from the durability and scratch resistance of ceramic.

Choosing between the GMT-Master II “Pepsi” and “Root Beer” ultimately comes down to personal preference. The “Pepsi” offers a bold and iconic look with its red and blue bezel, reminiscent of the brand’s heritage. On the other hand, the “Root Beer” exudes a sense of elegance and warmth, making it a unique and versatile choice for those who appreciate its distinctive color scheme.

IV. What is the difference between the GMT-Master II “Pepsi” and “Coke”?

The “Pepsi” and “Coke” are two of Rolex’s most renowned GMT-Master II variants, known for their contrasting bezel colors. We’ll dissect the differences between these two models, exploring the allure of the “Coke” and how it stands apart from the “Pepsi.” Whether you’re drawn to the fiery red of the “Coke” or the cool elegance of the “Pepsi,” this section will provide valuable insights.

The GMT-Master II “Coke” is distinguished by its black and red bezel, reminiscent of the classic Coca-Cola color scheme. This bold and vibrant color combination sets it apart from the “Pepsi” with its red and blue bezel. While both models offer a striking visual contrast, the “Coke” exudes a sense of intensity and energy.

Rolex introduced the “Coke” bezel in the GMT-Master II collection in the 1980s, providing an alternative to the classic “Pepsi” for those who preferred a different color scheme. The “Coke” quickly gained popularity among collectors and enthusiasts, becoming an iconic choice in its own right.

In terms of historical significance, both the “Pepsi” and “Coke” have their own unique stories to tell. The “Pepsi” bezel, with its red and blue colors, was originally designed to distinguish between day and night hours during long-haul flights. The “Coke” bezel, with its black and red colors, offers a bold and dynamic look that has captured the imagination of many.

Choosing between the two ultimately comes down to personal style and preference. The “Pepsi” exudes a classic and timeless appeal, while the “Coke” offers a more contemporary and energetic aesthetic. Whichever model you choose, both the “Pepsi” and “Coke” are emblematic of Rolex’s commitment to excellence and innovation.
