The Rolex GMT-Master and its successor, the GMT-Master II, are arguably two of the most recognizable and coveted watches in the world. Their history is intertwined with aviation, exploration, and a relentless pursuit of horological excellence. While both models share a common lineage and fundamental function – displaying two time zones simultaneously – significant differences exist in their design, functionality, and overall character. This article will delve into the key distinctions between these iconic timepieces, exploring their histories, variations, and the experiences of owners.
A Brief History: The Genesis of the GMT-Master
The original Rolex GMT-Master, launched in the mid-1950s, was a direct response to the burgeoning needs of Pan Am pilots. These pilots needed a watch capable of displaying multiple time zones with ease and accuracy, a crucial requirement for navigating the increasingly complex global flight schedules. The result was a groundbreaking watch featuring a 24-hour hand, independent from the hour, minute, and second hands, allowing for the simultaneous display of two time zones. This innovative feature, coupled with Rolex's renowned reliability and robustness, quickly established the GMT-Master as an indispensable tool for professionals and adventurers alike. The early GMT-Masters, often referred to as "coke" (due to the red and black bezel) or "Pepsi" (with a red and blue bezel), are highly sought-after collector's items today, commanding significant premiums in the secondary market.
1983: The Birth of the GMT-Master II and its Significance
In 1983, Rolex made their most significant update to the model. That year, the GMT-Master II was born with a crucial improvement: a bi-directional rotating bezel with an independent 24-hour hand that could be independently adjusted. This was a game-changer. In the original GMT-Master, adjusting the 24-hour hand also affected the hour hand. The GMT-Master II's independent adjustment allowed for more flexibility and precision in setting multiple time zones. This seemingly small change drastically improved the watch's usability and cemented its place as a highly practical and versatile travel companion. The introduction of the GMT-Master II marked a clear evolution, not just a refinement, of the original design.
Rolex GMT-Master II Versions: A Diverse Lineage
The GMT-Master II boasts a rich history of variations, each with its own unique characteristics and appeal. Understanding these variations is crucial for appreciating the breadth of the model's evolution. Here are some key models and their notable features:
* Ref. 16710: This reference, produced from 1989 to 2007, is often considered a sweet spot for many collectors. Its combination of classic design elements and improved functionality makes it a highly sought-after model. The "Pepsi" bezel variant of the 16710 is particularly popular.
* Ref. 16700: Preceding the 16710, this reference featured a slightly different case design and movement. It represents a transitional phase in the GMT-Master II's evolution.
