The arrow on a Rolex GMT-Master, often referred to as the 24-hour hand, is far more than just a stylistic element. It's a crucial component that defines the watch's core functionality and contributes significantly to its iconic status. This guide will delve into the intricacies of the GMT-Master's arrow hand, exploring its history, purpose, and significance within the broader context of Rolex's legendary GMT line. We'll also explore the various models, nicknames, and the overall history of this remarkable timepiece.
The Genesis of the GMT-Master and its Defining Arrow:
The story of the Rolex GMT-Master is intrinsically linked to the burgeoning era of transatlantic air travel. In the 1950s, Pan American World Airways (Pan Am) approached Rolex with a need for a watch that could accurately display time in multiple time zones simultaneously. The result was the groundbreaking Rolex GMT-Master, reference 6542, launched in 1955. This inaugural model featured a distinctive feature—a fourth hand, the 24-hour hand, often described as an arrow due to its shape in many iterations. This arrow hand, usually painted in a contrasting color, circled the dial once every 24 hours, indicating a second time zone independent of the standard hour, minute, and seconds hands.
This simple yet ingenious addition revolutionized the world of travel watches. Pilots and navigators could now effortlessly track their local time and a second time zone, typically their home base or a significant destination. The arrow hand, therefore, wasn't merely an aesthetic choice; it was the functional heart of the GMT-Master's groundbreaking design. Its distinct shape and contrasting color ensured immediate readability, even under challenging conditions.
A Deep Dive into Rolex GMT-Master Reference Numbers and Their Evolution:
The Rolex GMT-Master's journey has been marked by a succession of reference numbers, each reflecting refinements in design, materials, and movement. A complete list would be extensive, but some key models and their arrow hand variations warrant attention:
* Reference 6542 (1955-1959): The very first GMT-Master, featuring a relatively simple arrow hand design, often in a contrasting color like red. This model laid the foundation for all future iterations.
* Reference 1675 (1959-1980): This reference saw several variations, notably the introduction of different bezel materials and colors. The arrow hand design continued to evolve subtly, with variations in shape and color becoming more pronounced in later sub-references.
* Reference 16750 (1980-1989): This model introduced improvements to the movement, but the overall design remained consistent with the previous generation. The arrow hand remained a key identifying feature.
* Reference 16700 (1983-1999): This saw some changes in the movement and a slightly more refined aesthetic. Again, the arrow hand continued to play its vital role.
* Rolex GMT-Master II (1983 - Present): The introduction of the GMT-Master II marked a significant leap forward. The most notable difference was the independently adjustable 24-hour hand, allowing for greater flexibility in setting a second time zone. The arrow hand design continued to be refined, with variations in color and shape across different models. This model solidified the arrow's role as a critical identifying feature of the GMT-Master line.
