One of the most celebrated timepieces in horological history is the Rolex GMT-Master. This iconic watch has a rich history filled with technological advancements, distinct features, and a host of celebrity wearers. Join us as we explore the evolution and enduring appeal of the Rolex GMT-Master among watch enthusiasts and collectors alike.
Introducing the Rolex GMT-Master
The Rolex GMT-Master was born from a collaboration between Rolex and Pan American World Airways (Pan Am) in the mid-1950s. As commercial air travel expanded, pilots and crew needed a reliable way to track multiple time zones during long-haul flights. Pan Am approached Rolex to create a watch specifically designed to meet this need.
In 1954, Rolex introduced the GMT-Master, reference 6542, at the Basel Watch Fair. The watch featured a groundbreaking design that allowed wearers to simultaneously read the time in two different time zones. This was achieved through a 24-hour hand and a bi-directional rotating bezel. The GMT-Master quickly became the go-to watch for pilots and travellers, solidifying its reputation as the ultimate tool watch for international jet-setters.
What are the Defining Features of the Rolex GMT-Master?
Several defining features set the Rolex GMT-Master apart from other timepieces, making it a favourite among professionals and collectors alike.
Dual Time Zone Functionality
The primary feature of the GMT-Master is its ability to display two time zones simultaneously. The 24-hour hand, paired with the rotatable bezel marked with 24-hour graduations, allows wearers to easily set and track a second time zone. This functionality was handy for pilots tracking local and home time.
Rotatable Bezel
The GMT-Master’s rotatable bezel is not just functional but also a key design element. Initially, the bezels were made from Bakelite, a type of early plastic. However, Bakelite proved to be fragile, and Rolex soon switched to more durable aluminium inserts. The bezel’s bi-colour design, with one colour representing daytime hours and the other representing nighttime hours, has become an iconic feature of the GMT-Master.
Robust Construction
As with all Rolex watches, the GMT-Master is built to last. The watch features a robust Oyster case, offering excellent water resistance and protection against dust. Early models were water-resistant, up to 50 metres, while modern versions can withstand depths of up to 100 metres. The watch is also fitted with a durable bracelet, usually the Jubilee or Oyster, ensuring both comfort and longevity.
Luminescent Markers
The GMT-Master’s dial features luminescent markers and hands, ensuring legibility in low-light conditions. Early models used radium and later tritium, while current models use Chromalight, emitting a long-lasting blue glow that enhances readability.
The Evolution of the Rolex GMT-Master
Over the decades, the Rolex GMT-Master has undergone numerous changes and improvements. Each iteration has added new features and refinements, enhancing both functionality and aesthetics.
1950s: The Bond Years
The original GMT-Master, reference 6542, was produced from 1954 to 1959. This model featured a Bakelite bezel insert with luminous numerals and a no-crown guard case. However, the fragility of the Bakelite led to its replacement with an aluminium bezel insert. The reference 6542 was famously worn by Honor Blackman’s character, Pussy Galore, in the James Bond film “Goldfinger.”
1960s: ‘Pepsi’
In 1959, Rolex introduced the reference 1675, a model that remained in production until 1980. The reference 1675 featured several significant updates, including crown guards to protect the winding crown and an aluminium bezel insert. The watch also saw the debut of the Jubilee bracelet as an option. The reference 1675 is often associated with its “Pepsi” bezel, named for its red and blue colour scheme.
1980s: White Gold Hour
The reference 16750, introduced in 1981, brought significant improvements, including the new calibre 3075 movement with a quickset date function. This allowed wearers to set the date independently of the time, enhancing convenience. The reference 16750 also featured an updated dial with a glossy finish, and white gold surrounds for the hour markers.
1990s: The GMT-Master II
The 1990s marked a transformative period for the GMT-Master line with the introduction of the GMT-Master II, reference 16710. The GMT-Master II featured a new calibre 3185 movement, allowing the hour hand to be adjusted independently of the 24-hour hand. This innovation enabled the tracking of three time zones — one with the traditional hour hand, one with the 24-hour hand, and one by rotating the bezel. The reference 16710 also saw the revival of the classic “Pepsi” bezel and the introduction of the “Coke” bezel with red and black colours.
2000s to Present: Modern Masterpieces
The GMT-Master II continued to evolve in the 21st century with further enhancements in materials and technology. In 2005, Rolex introduced the reference 116710LN, featuring a Cerachrom ceramic bezel insert, which is highly resistant to scratches and fading. The watch also included an upgraded calibre 3186 movement and a new Triplock crown for improved water resistance.
More recent updates include the reference 126710BLRO, introduced in 2018. This brought back the classic “Pepsi” bezel in ceramic and featured the new calibre 3285 movement with Rolex’s Chronergy escapement, providing enhanced precision and power reserve. The modern GMT-Master II models continue to uphold the collection’s legacy of innovation and reliability.
