The Rolex GMT-Master, and its successor the GMT-Master II, are iconic timepieces renowned for their functionality, durability, and enduring style. These watches, instantly recognizable by their rotating bezel and GMT hand, have captivated collectors and enthusiasts for decades. Understanding the nuances of the GMT-Master series, from its intricate reference numbers to the variations in bezel materials and colors, is crucial for accurate dating, authentication, and valuation. This article will explore the complexities of the Rolex GMT-Master and GMT-Master II, focusing on key aspects to aid both seasoned collectors and those newly exploring this legendary watch.
Decoding the Reference Numbers: A Key to Authentication and Dating
The reference number is the cornerstone of identifying a specific Rolex GMT-Master model and its production year. These numbers, often subtly engraved on the case, provide a wealth of information. While the visual appearance of a watch can be deceiving, the reference number offers an objective means of verification. Understanding these codes is vital for accurate dating and authentication, helping to distinguish genuine Rolex watches from counterfeits.
The reference numbers for the GMT-Master and GMT-Master II follow a specific system, with slight variations throughout their history. Let's examine some key examples:
* GMT-Master (16xx series): The early GMT-Master models, predominantly from the 1950s to the 1980s, are identified by reference numbers beginning with "16". These include references like 1675, 16750, and 16710, each indicating specific variations in case size, movement, and features. For example, the 1675 is known for its acrylic crystal and Bakelite bezel insert, while the 16710 features a sapphire crystal and a more robust movement. Careful examination of the caseback and movement will further aid in accurate dating within this series.
* GMT-Master II (167x, 1167x, & 1267x series): The GMT-Master II, introduced in 1983, features a more advanced movement allowing for independent adjustment of the GMT hand. Its reference numbers generally start with "167," "1167," or "1267," again denoting specific model variations. The 16710, for instance, represents an early GMT-Master II, while the 116710LN and 126710BLRO represent more recent iterations. The "LN" and "BLRO" suffixes indicate bezel and dial configurations, which we will explore in detail below. The three-digit prefix reveals significant changes in the case size and movement technology over time.
Understanding these reference number variations is crucial for determining the age and specific features of a particular Rolex GMT-Master. Online resources and reputable dealers specializing in Rolex watches offer comprehensive reference guides to aid in this process. Cross-referencing the reference number with known production dates and features is the most reliable authentication method. Furthermore, examining the movement for hallmarks and serial numbers provides additional verification.
Bezel Types: A Spectrum of Style and Functionality
The bezel is a defining characteristic of the GMT-Master, playing both an aesthetic and functional role. Various bezel types have been used throughout the watch's history, each with its own unique characteristics:
