The iconic, rotating bezel of the Rolex GMT-Master and GMT-Master II is more than just a stylistic element; it's a crucial component of the watch's functionality, enabling the wearer to track a second time zone with remarkable ease. Largely popularized by these models, a standard GMT bezel, regardless of the specific model, comes in a few flavors, but the core functionality remains consistent: the ability to track a second time zone simultaneously with local time. This article will delve deep into the various aspects of the Rolex GMT bezel, exploring its function, different types, replacement options, and how to identify authentic components.
Understanding the Functionality of the Rolex GMT Bezel
The GMT bezel's primary function revolves around its 24-hour graduated scale. Unlike the typical 60-minute markings found on most bezels, this 24-hour scale allows for the tracking of a second time zone. The watch's independently adjustable GMT hand, often colored differently (typically red), points to the time in the second time zone. By rotating the bezel until the 24-hour marker aligns with the GMT hand, the wearer can quickly read the time in both their local time zone and the second time zone. This simple yet ingenious system makes the GMT-Master and GMT-Master II highly sought-after travel watches. The bidirectional rotation of the bezel adds to its practicality, allowing for quick adjustments without needing to remove the watch.
Different Types of Rolex GMT Bezels
While the core functionality remains consistent, Rolex offers variations in the materials and aesthetics of its GMT bezels. These variations contribute to the diverse appeal of the GMT-Master and GMT-Master II lines. Some of the most common types include:
* Aluminum Bezels: These are the most classic and widely recognized GMT bezels. They typically feature a matte finish and come in various colors, including black, blue, red-and-blue (Pepsi), and green-and-black (Batman). The aluminum bezels offer a lightweight feel and are relatively durable, although they are prone to scratches over time.
* Cerachrom Bezels: Introduced by Rolex, Cerachrom bezels are made from a high-tech ceramic material. This material offers exceptional scratch resistance, ensuring the bezel maintains its pristine appearance for years to come. They are available in various colors, including black, blue, and brown, often with contrasting numerals and markers. The Cerachrom bezel's superior durability and resistance to fading make it a significant upgrade over the aluminum version.
* Gold Bezels: Rolex also offers GMT bezels crafted from precious metals, such as yellow gold, white gold, or rose gold. These bezels exude luxury and sophistication, adding a touch of opulence to the watch. They are typically more expensive than their aluminum or ceramic counterparts.
* Diamond-Set Bezels: For those seeking ultimate luxury, Rolex offers GMT bezels adorned with diamonds. These bezels are meticulously crafted with high-quality diamonds, adding a dazzling sparkle to the already iconic design. These are, naturally, the most expensive option.
