The Rolex GMT-Master II Root Beer: A Complete Guide to an Icon

There are watches, and then there are watches that stop conversations. The Rolex GMT-Master II Root Beer is very much the latter. Named informally for its warm blend of brown and gold tones that resemble the classic American soft drink, this particular reference has earned a reputation that stretches well beyond the collector community. It is sophisticated without being loud, rare without being inaccessible to understand, and historical without feeling dated. If you have been curious about what makes the Root Beer so compelling, this guide walks through everything you need to know, from its origins to what sets it apart in the secondary market today.

A Brief History of the GMT-Master Line

To appreciate the Root Beer, you first need to understand the line it comes from. Rolex introduced the GMT-Master in 1955, originally developed in partnership with Pan American World Airways. Pilots needed a reliable way to track two time zones simultaneously during transatlantic flights, and the GMT-Master delivered exactly that. The rotating bezel, paired with a 24-hour hand, allowed wearers to read a second time zone at a glance. It was a tool watch in the truest sense, built for professionals operating at altitude. Over the following decades, Rolex refined the concept, eventually launching the GMT-Master II in 1983 with an independently adjustable hour hand, which allowed wearers to set local time without disrupting the GMT reference hand. That upgrade made it significantly more practical for frequent travelers and cemented the GMT-Master II as a modern standard for dual-timezone watches.

Where the Root Beer Name Comes From

Collectors have a long tradition of giving Rolex references informal nicknames based on their dial or bezel color combinations. The Pepsi, the Batman, the Sprite, the Coke. The Root Beer earned its nickname from the distinctive brown and gold color pairing of its bezel insert. Depending on the reference year and material, the tones can range from a deep espresso brown to warmer caramel hues, all set against the richness of yellow gold or Everose gold case materials. The combination has a warmth that feels distinctly different from the cooler, more sporty colorways in the GMT-Master II family, which is part of why it has attracted such devoted admirers.

Key References You Should Know

Not all Root Beers are created equal, and understanding the different references helps when evaluating a purchase or simply educating yourself on what exists in the market. Here is a quick breakdown of the most significant iterations:

Reference 16753 introduced the brown and gold bezel in the 1980s on a steel and yellow gold case, often called the two-tone version. Reference 16713 continued the tradition through the 1980s and 1990s, featuring a Jubilee bracelet option and tritium or luminova dial variations depending on production year. Reference 126711CHNR, released in 2019, marked the return of the Root Beer on an Everose gold and Oystersteel case with a ceramic bezel insert, representing the modern interpretation of the colorway. Reference 126715CHNR features a full 18k Everose gold case with a matching ceramic bezel and is considered the flagship of the current Root Beer lineup.

Each reference carries different market values, wearability considerations, and collector appeal. The vintage references tend to attract purists, while the modern ceramic bezel versions appeal to buyers seeking durability and a polished contemporary finish.

What Makes the Ceramic Bezel a Game Changer

For years, the GMT-Master II bezel inserts were made from aluminum, which was functional but susceptible to fading and scratching over time. Rolex transitioned to Cerachrom ceramic inserts, and it changed the conversation around longevity. Ceramic is extraordinarily resistant to UV exposure, meaning the colors do not fade the way aluminum inserts do. It is also significantly harder to scratch, which matters on a watch that is meant to be worn. The modern Root Beer references use a brown and black Cerachrom insert, which is technically a departure from the all-brown aluminum of the vintage models, but the result is a bezel that maintains its appearance indefinitely under normal conditions. For buyers who intend to wear the watch regularly rather than store it in a collection, this is a meaningful practical consideration.

Movement and Technical Specifications

The current GMT-Master II Root Beer references are powered by the Rolex Caliber 3285, an in-house movement that represents one of the more capable automatic movements in production watchmaking today. It features a Chronergy escapement, which improves energy efficiency, along with a power reserve of approximately 70 hours. The movement is also certified as a Superlative Chronometer by Rolex, which means it has been tested to an accuracy of plus or minus two seconds per day, exceeding the standard COSC certification requirements. The case measures 40mm in diameter, which has become the benchmark size for this line, offering a proportionate fit across a wide range of wrist sizes. Water resistance is rated to 100 meters, which is appropriate for everyday wear though not designed for serious diving.

The Root Beer in the Collector Market

Market behavior around the Root Beer has remained consistently strong. Vintage references in good condition with original dials and intact bracelets command significant premiums, particularly those from the 1980s with original tropical dials or well-preserved aluminum bezels showing minimal fading. The modern references, particularly the two-tone Everose versions, have maintained robust secondary market values since their 2019 introduction. Buyers in the pre-owned space should pay close attention to the condition of the dial, the completeness of the original documentation, and the service history. A Root Beer with its original box and papers from a reputable dealer carries substantially more value than one sold without provenance.

How to Authenticate and What to Look For

Given the value attached to Root Beer references, authentication is a non-negotiable part of the buying process. A few areas deserve careful attention:

Examine the case finishing, which should feature a precise combination of brushed and polished surfaces with no signs of uneven grinding or refinishing. Inspect the dial closely for correct fonts, proper spacing on the text, and original lume that has aged consistently across all indices. Verify the serial number, which can place the watch within a specific production year and confirm whether the components match that era. Confirm the movement through a trusted watchmaker, particularly on vintage references where parts substitution is a known concern.

Buying from established, reputable sources remains the most reliable safeguard against counterfeits or misrepresented examples in this category.
