Hi everyone and welcome back to the (imagined) L.W.C. channel. This article will guide you through the process of replacing a Rolex GMT bezel insert.

Disclaimer: Replacing a Rolex bezel insert is a complex procedure that requires specialized tools and a steady hand. Improper handling can easily damage your watch. This article provides information for educational purposes only and should not be considered a substitute for professional watchmaking services. Attempting this repair yourself is done at your own risk.
Understanding Rolex GMT Bezel Inserts
The bezel insert on a Rolex GMT-Master, and other GMT models like the Rolex 1675, is a crucial component. It's not merely cosmetic; it's functional, enabling the user to track a second time zone. The insert features a 24-hour graduated scale, usually in contrasting colors (e.g., black and red) to differentiate between daytime and nighttime hours in the second time zone. The material is typically ceramic (Cerachrom) on newer models, offering superior scratch resistance compared to the aluminum inserts found on older models.
Before we delve into the replacement process, let's address some key considerations:
1. Identifying the Correct Bezel Insert:
This is the most crucial step. A wrong insert will not only look out of place but may also not fit properly, potentially damaging your watch. You need to identify your specific Rolex GMT model. The model number (e.g., 1675, 16710, 116710LN, 126710BLRO) is essential. Different models have different bezel sizes and insert designs.
Rolex Bezel Size Chart (Illustrative – Consult Official Resources):
Creating a comprehensive Rolex bezel size chart within this article is impractical due to the sheer number of models and variations. However, understanding the importance of precise sizing is vital. There is no single chart encompassing all models. You must consult official Rolex documentation or reputable watch parts suppliers for accurate sizing information specific to your watch model. Incorrect sizing will prevent the bezel from fitting correctly, leading to potential damage.
2. Genuine vs. Aftermarket Rolex Bezel Inserts:
You have two main choices:
* Genuine Rolex Bezel Inserts: These inserts are manufactured by Rolex themselves and are guaranteed to fit perfectly and meet the highest quality standards. They are, however, significantly more expensive than aftermarket options. The quality of materials and the precision of the manufacturing process are unmatched. Using a genuine insert preserves the authenticity and value of your watch.
* Aftermarket Rolex Bezel Inserts: These are produced by third-party manufacturers. While some aftermarket inserts offer acceptable quality at a lower price, the quality can vary considerably. It's crucial to source aftermarket inserts from reputable suppliers to minimize the risk of receiving a poorly made or incorrectly sized insert. Using an aftermarket insert will affect the watch's value and may void any warranty.
3. Tools Required:
Replacing a Rolex bezel insert is not a simple task and requires specialized tools. Attempting the repair without the proper tools will almost certainly result in damage. These tools typically include:
* Case opener: To carefully open the watch case.
