This comprehensive guide details the process of replacing a bezel insert on a Rolex GMT Master II (specifically referencing the 16710, but applicable to other models with similar designs) and a Rolex Submariner (specifically referencing the 16610, again applicable to similar models). While seemingly straightforward, this task requires precision and the right tools to avoid damaging your valuable timepiece. We'll cover everything from sourcing the correct insert to the meticulous steps involved in the replacement. This guide is intended for informational purposes only; attempting this repair without proper experience carries the risk of damaging your watch. Professional service is always recommended.
Understanding the Components: Rolex Replacement Bezel Insert
Before diving into the process, let's clarify the terminology and components involved. We're focusing on the bezel *insert*, which is the colored ring on the bezel itself. The bezel is the rotating outer ring, and the insert is the part that provides color and markings (e.g., numerals, markers, GMT graduations). This guide focuses on replacing the insert, not the entire bezel assembly.
There are several types of bezel inserts available:
* Genuine Rolex Bezel Insert: These are original Rolex parts, guaranteeing perfect fit and quality. They are usually more expensive but offer superior durability and authenticity. Finding genuine inserts, especially for older models like the 1675, can sometimes be challenging, requiring searches through authorized dealers or reputable watch parts suppliers.
* Aftermarket Rolex Bezel Insert: These inserts are manufactured by third-party companies and are generally cheaper than genuine Rolex parts. The quality can vary significantly, and some aftermarket inserts may not fit perfectly or have inferior materials. Careful research and selection are crucial when considering aftermarket options. Pay close attention to reviews and ensure the seller specifies compatibility with your specific Rolex model (e.g., 16710, 16610, 1675).
* Rolex GMT Bezel Replacement: This term refers specifically to the replacement of the bezel insert on a Rolex GMT Master model. The process is generally similar across different GMT models, but slight variations may exist depending on the reference number (e.g., 16710, 1675, 116710LN).
* Rolex 1675 Bezel Insert: The Rolex GMT Master 1675 is a vintage model with a unique bezel insert design. Finding a genuine replacement for this model can be particularly difficult and expensive. Aftermarket options are more readily available but require careful consideration of quality and fit.
* Rolex GMT Master Bezel Insert: This is a general term encompassing bezel inserts for all Rolex GMT Master models. The process of replacement is similar, but the specific insert design will vary based on the model and year.
* Rolex GMT 1675 Bezel: This refers to the entire bezel assembly, including the insert, on the Rolex GMT Master 1675. This guide focuses only on replacing the insert, not the entire bezel.
Rolex Bezel Size Chart
While a precise Rolex bezel size chart isn't publicly available, understanding that bezel inserts are model-specific is crucial. An insert from a Submariner will *not* fit a GMT Master, and vice versa. Even within the same model line (e.g., GMT Master II), variations exist between reference numbers and years of production. Always verify compatibility before purchasing a replacement insert. Reputable sellers will typically specify the compatible model numbers.
