Few luxury watches inspire as much passion, storytelling, and collector obsession as the Rolex GMT-Master II. Originally designed for Pan American Airways pilots in the 1950s, the GMT line has grown into one of the most recognizable travel watches on earth. But beyond its exceptional engineering and timeless aesthetics, what truly sets the GMT-Master II apart is the series of iconic nicknames enthusiasts have given its various bezel colorways.

These fan-coined nicknames not only help identify references quickly but also reflect the cultural impact of the GMT line itself. Below is a deep dive into the most legendary Rolex GMT-Master II nicknames and what makes each one so special.

 

Rolex GMT-Master II “Pepsi”

The Rolex Pepsi is arguably the most famous GMT of all time. With its bold blue-and-red bezel, the watch instantly evokes the look of a classic Pepsi cola can—hence the nickname. First introduced in the 1950s, the color combination was originally practical: red symbolized daylight hours and blue represented nighttime for easy reading of a second time zone.

In the modern era, the Pepsi exists primarily in stainless steel or white gold with a ceramic (Cerachrom) bezel, making it both visually striking and mechanically robust. For collectors, the Pepsi remains the quintessential GMT-Master II and a cornerstone of Rolex design heritage.

 

Rolex GMT-Master II “Batman”

Introduced in 2013, the Rolex Batman—reference 116710BLNR—features a black-and-blue bezel that immediately reminded the watch community of Gotham’s caped crusader. The cool-toned ceramic bezel, combined with Rolex’s sleek Oyster bracelet (later available on Jubilee), gave the Batman a distinctly modern and stylish feel.

Collectors love the Batman not only for its aesthetics but also because it was Rolex’s first two-tone ceramic bezel. It continues to be one of the most sought-after steel sports models in the brand’s lineup.

 

Rolex GMT-Master II “Batgirl”

When Rolex reintroduced the black-and-blue bezel in 2019 with a Jubilee bracelet, enthusiasts felt the more elegant and dress-forward design deserved its own name. Hence, the Batgirl was born. The watch retains the beloved BLNR ceramic bezel but appears visually softer and more refined compared to the original Batman.

Between the sleek case, Jubilee bracelet, and updated movement (Caliber 3285), the Batgirl has become a massive hit with collectors, offering a perfect blend of playfulness and sophistication.

 

Rolex GMT-Master II “Coke”

The Coke GMT, featuring a black-and-red aluminum bezel, is another beloved classic. Resembling the red and black tones of a Coca-Cola can, the Coke bezel was featured on several references (most famously 16710) before Rolex discontinued aluminum bezel inserts entirely in favor of ceramic.

Because a ceramic Coke GMT does not currently exist, collectors often speculate about whether Rolex will ever revive this colorway. Until then, vintage and neo-vintage Coke references continue to appreciate as collectors hunt for well-preserved examples.

 

Rolex GMT-Master II “Root Beer”

The deliciously nicknamed Root Beer GMT features a mix of brown and black (or brown and gold, depending on the era). The earliest Root Beer models from the 1970s used aluminum inserts and developed a cult following among vintage Rolex aficionados.

The modern Root Beer (reference 126711CHNR and 126715CHNR) brings the concept into the 21st century with Everose gold accents and a sleek ceramic bezel. The result is a warm, luxurious aesthetic that has made the Root Beer one of the most distinctive GMT-Master II variations today.

 

Rolex GMT-Master II “Sprite”

In 2022, Rolex shocked collectors by releasing a left-handed (destro) GMT-Master II with a green-and-black bezel—a first in the brand’s history. The watch quickly earned the nickname Sprite thanks to its bright green hue paired with the pop of black ceramic.

Whether you love or hate the unconventional crown placement, the Sprite has become one of the most buzz-worthy modern Rolex releases, offering an unexpected twist on the decades-old GMT formula.

 

Why These Nicknames Matter

Rolex has never officially endorsed these nicknames, yet they’ve become ingrained in watch culture. They serve three important purposes:

 

1. Easy Identification – Saying “Pepsi” or “Batman” is far easier than reciting reference numbers like 126710BLRO.

2. Community & Traditions – Nicknames create shared language among collectors, fostering discussion and connection.

3. Market Influence – A catchy nickname can significantly boost desirability and even resale value.

 

Final Thoughts

From the iconic Pepsi and Coke to the modern Batman, Batgirl, and Sprite, the Rolex GMT-Master II lineup is filled with colorways that collectors adore and instantly recognize. These nicknames have become part of horological history, symbolizing not just the watch’s visual appeal but also the culture and enthusiasm surrounding Rolex.

If you’re considering adding a GMT-Master II to your collection—or simply want to better understand the language of watch enthusiasts—these nicknames are essential knowledge.
