The Complete History of the Rolex GMT-Master: From Pan Am to the Stars
The Rolex GMT-Master is far more than a luxury timepiece — it is a symbol of adventure, precision, and human progress. From the cockpit of Pan Am airliners in the 1950s to the astronauts orbiting the Moon, this watch has accompanied travelers who defined an era. Its evolution tells the story of how one of Rolex’s most iconic sports watches became a global legend, admired for its dual-time functionality and unmistakable design.
1. The Birth of a Legend: The 1955 Rolex GMT-Master
In the mid-1950s, as commercial aviation expanded across continents, Pan American World Airways sought a tool for its pilots to track two time zones simultaneously — home base and destination. Rolex responded with an ingenious design: a rotating 24-hour bezel combined with an additional hand completing one rotation per day. The result was the first Rolex GMT-Master, reference 6542, introduced in 1955.
The model’s red-and-blue “Pepsi” bezel became instantly recognizable. The colors weren’t just aesthetic — red indicated daylight hours, blue night-time. The earliest bezels were made of luminous Bakelite, allowing pilots to read them in the dark. Though fragile, this innovation marked the birth of a horological icon.
Just four years later, the GMT-Master proved its reliability during the first non-stop Pan Am flight from New York to Moscow in 1959. Captain C. N. Warren, at the controls of the Boeing 707, famously stated that “the flight itself was navigated by Rolex.” In the midst of the Cold War, the watch not only guided time but symbolized a rare connection between East and West.
2. The Evolution of the GMT-Master I: From Bakelite to Aluminum
Real-world use quickly revealed that Bakelite was too fragile for a pilot’s watch, leading Rolex to replace it with aluminum on the GMT-Master Ref. 1675 introduced in 1959. The case grew from 38 mm to 40 mm and gained crown guards for added robustness. The reference 1675 remained in production for more than two decades — a testament to its timeless design.
Through the 1960s and 1970s, Rolex offered multiple versions in stainless steel, yellow gold, and two-tone configurations. Bezel colors multiplied: the classic “Pepsi”, the brown-and-gold “Root Beer,” and the understated all-black. Inside, calibers evolved from 1565 to 1575 and 3075, improving precision and reliability.
During this era, the Rolex GMT-Master accompanied explorers on extraordinary journeys. One of the most notable was the Pegasus Overland Expedition in 1959, where eight British Army adventurers drove around the world through 34 countries over 51 weeks — each equipped with a GMT-Master. Their journey showcased the watch as a symbol of endurance and discovery.
3. The GMT-Master II: The Next Generation for the Jet Age
In 1982, Rolex unveiled a major innovation: the GMT-Master II. Externally similar to its predecessor, it introduced a mechanically independent 12-hour hand. This meant travelers could adjust local time without affecting the 24-hour hand — a true advancement for global pilots.
The debut model, Ref. 16760, earned the nickname “Fat Lady” for its thicker case. It came only in stainless steel with a red-and-black “Coke” bezel. A few years later, the slimmer Ref. 16710 offered more variations — from the classic Pepsi to all-black bezels — as well as gold and two-tone versions. The GMT-Master II became not just a pilot’s instrument but a lifestyle statement.
Throughout the 1980s and 1990s, Rolex refined the model’s movements (Caliber 3085, 3185, and 3186) and strengthened its Oyster case to 100 meters water-resistance. By the time of the 2000s, the GMT-Master II had become an icon for world travelers and collectors alike.
4. Innovation in Material: The Cerachrom Era
A new chapter began in 2005 when Rolex introduced the Cerachrom bezel, a proprietary ceramic alloy virtually impervious to fading and scratches. The GMT-Master II Ref. 116718, crafted in 18 k yellow gold, was the first to showcase this cutting-edge material. The following year saw a two-tone 116713, and 2007 brought the stainless-steel 116710 — all featuring sleek black Cerachrom bezels.
Initially, Rolex declared a two-tone ceramic bezel impossible to manufacture. But in 2013, the brand accomplished the unimaginable: the GMT-Master II Ref. 116710BLNR, nicknamed the “Batman,” with a black-and-blue Cerachrom bezel. One year later came the white-gold Ref. 116719BLRO “Pepsi,” bringing the beloved red-and-blue combination back in brilliant ceramic.
Each innovation reaffirmed the GMT-Master’s blend of tradition and technology. The case and bracelet designs became more refined, and the collection introduced the Jubilee bracelet option alongside the traditional Oyster, appealing to both vintage enthusiasts and modern collectors.
5. The Modern GMT-Master II: Caliber 3285 and New Horizons
In 2018, Rolex equipped the GMT-Master II with the revolutionary Caliber 3285 movement. Featuring 70 hours of power reserve, improved precision, and greater energy efficiency, this marked a new standard in Rolex engineering.
Several stunning references were launched:
126710BLRO – Oystersteel with red/blue “Pepsi” Cerachrom bezel on Jubilee bracelet.
126711CHNR – Everose Rolesor (two-tone steel and Everose gold) with brown/black “Root Beer” bezel.
126715CHNR – Solid Everose gold version.
126719BLRO – White gold Pepsi edition.
A year later came the 126710BLNR “Batman” on Jubilee, and in 2021 both the Pepsi and Batman models were offered with a choice between Oyster and Jubilee bracelets.
Then in 2022, Rolex stunned the industry with the 126720VTNR — a left-handed “Destro” model featuring a green-and-black Cerachrom bezel and the crown on the left side. It was the first Rolex sports watch specifically designed for left-hand wearers.
6. The Rolex GMT-Master in Aviation and Space
The Rolex GMT-Master’s story doesn’t end with civil aviation. Its legacy extended into some of humanity’s most daring frontiers.
From 1959 to 1968, NASA and the U.S. Air Force conducted the X-15 rocket-plane program, pushing flight to Mach 6.7. Pilot William J. Knight wore a GMT-Master during his record-breaking mission in 1967 — proof of the watch’s ability to endure extreme conditions.
In 1970, Apollo 13 astronaut Jack Swigert relied on his Rolex GMT-Master throughout the disastrous mission that nearly cost three lives. Swigert used precise timing to adjust the module’s trajectory and ensure the crew’s safe return to Earth.
Two years later, during Apollo 17, the final manned lunar mission, Captain Ronald Evans wore his GMT-Master while orbiting the Moon and performing a spacewalk. The watch had literally traveled beyond our planet — a fitting testament to its engineering excellence.
7. The Rolex GMT-Master Today: A Modern Icon
More than sixty years after its debut, the Rolex GMT-Master remains a symbol of sophisticated travel and technical mastery. Its ability to track multiple time zones, paired with timeless design and unmatched craftsmanship, keeps it at the top of collectors’ wish lists worldwide.

FAQ
What is the Rolex GMT-Master and what was it originally designed for?
The Rolex GMT-Master is a professional pilot’s watch created in the 1950s to help airline crews track multiple time zones at once. It combines a 24-hour hand with a rotating bezel, allowing the wearer to read local time and a second reference time simultaneously – a crucial feature for early long-haul aviation.
What is the difference between the Rolex GMT-Master and GMT-Master II?
Both models look similar, but the Rolex GMT-Master II features an independently adjustable 12-hour hand. That means you can change local time in one-hour jumps without stopping the movement or disturbing the 24-hour hand, making it even more practical for frequent travelers. The original GMT-Master keeps the 12- and 24-hour hands mechanically linked.
What do the Rolex GMT-Master bezel colors mean (Pepsi, Coke, Batman, Sprite)?
The colored bezels on the Rolex GMT-Master and GMT-Master II started as a functional day/night indicator: typically red for daytime hours and blue for night on the classic “Pepsi” bezel. Over time, nicknames emerged – “Pepsi” (red/blue), “Coke” (red/black), “Batman” (black/blue) and “Sprite” (green/black) – and each color combination has become a collectible aesthetic in its own right.
When was the Rolex GMT-Master first released?
The first Rolex GMT-Master (reference 6542) was introduced in 1955 for Pan Am pilots flying intercontinental routes. It used a bakelite bezel with a 24-hour scale and a red-and-blue colour split to help crews quickly distinguish between day and night hours in a second time zone.
Why is the Rolex GMT-Master so expensive and desirable?
The Rolex GMT-Master is expensive because it combines high-end materials, in-house movements, strict quality control and strong brand prestige. Steel sports models in particular are produced in limited quantities relative to demand, which pushes secondary-market prices above retail. Its history with commercial aviation and space exploration adds to its status among collectors.
Is the Rolex GMT-Master a good investment watch?
No watch is guaranteed to increase in value, but historically, steel sports models like the Rolex GMT-Master and GMT-Master II have held value well and often trade above their original retail price on the pre-owned market. Rarity, condition, original parts and desirable references or bezel colours all play a major role in long-term value.
How much does a Rolex GMT-Master cost on the pre-owned market?
Pre-owned Rolex GMT-Master prices vary widely depending on reference, age, condition, box and papers, and bezel variant. While some well-used or older pieces may start below the price of a new model, popular or rare references can reach many tens of thousands of dollars and exceptional vintage examples can achieve six-figure auction results.
How often should I service a Rolex GMT-Master?
Rolex generally recommends having a watch inspected and serviced roughly every 10 years, though actual intervals depend on how and where it’s worn. Vintage Rolex GMT-Master models or heavily used watches may benefit from more frequent servicing (for example every 5–7 years) to maintain water resistance, lubrication and accuracy.
How accurate is a Rolex GMT-Master supposed to be?
Modern Rolex GMT-Master and GMT-Master II models are certified as Superlative Chronometers, which means Rolex regulates them to within −2/+2 seconds per day after casing – a stricter standard than the usual COSC chronometer certification. Older models might not match this exact spec but are still built for high everyday accuracy.
Is the Rolex GMT-Master water resistant?
Yes. Most Rolex GMT-Master and GMT-Master II models are rated to 100 meters (330 feet) of water resistance, thanks to the Oyster case and screw-down crown. That’s more than enough for daily wear, rain, and swimming, though they’re not designed as dedicated professional dive watches.
How can I tell if a Rolex GMT-Master is authentic?
Checking authenticity of a Rolex GMT-Master involves examining case and bracelet quality, the engraving and logo details, the smoothness of the movement, the serial and reference numbers, and the alignment and finishing of the dial and bezel. Because counterfeiters are increasingly sophisticated, serious buyers usually rely on trusted dealers or independent watchmakers to verify authenticity.
What are the most important reference numbers in Rolex GMT-Master history?
Some of the key Rolex GMT-Master and GMT-Master II references include:
6542 – the original 1955 GMT-Master with bakelite bezel
1675 – long-running classic Pepsi model
16750 / 16700 – transitional GMT-Master references with upgraded movements
16760 / 16710 – early GMT-Master II references (including “Fat Lady” and classic Coke/Pepsi variants)
116710 / 116710BLNR / 116719BLRO – early Cerachrom bezel generation
126710, 126719, 126720VTNR – latest generation with Caliber 3285 and new bezel colours, including the left-handed “Sprite”.
Why is it so hard to buy a Rolex GMT-Master II at retail?
Demand for the Rolex GMT-Master II far exceeds the number of watches allocated to authorized dealers. Many clients join waiting lists, and some boutiques prioritise established customers with purchase history. As a result, the model is often easier to find on the secondary market than at an official retailer, but usually at a premium over list price.
Can you wear a Rolex GMT-Master every day?
Yes. The Rolex GMT-Master was originally built as a professional tool watch, so it’s robust enough for daily wear. Its combination of water resistance, shock resistance and scratch-resistant materials on modern models makes it suitable for travel, office, and casual use – while still elegant enough for more formal occasions.
