Replacing a Rolex Submariner crystal, whether it's the acrylic (plastic) version found on vintage models or the more modern sapphire crystal, is a delicate procedure best left to experienced watchmakers. However, understanding the process can help you appreciate the complexity involved and make informed decisions about repairs. This detailed guide explores the steps involved in replacing both acrylic and sapphire crystals, highlighting the key differences and challenges. We'll also delve into the costs associated with professional repairs and provide insights into finding reputable watchmakers.
Understanding the Rolex Submariner Crystal
The crystal, or watch glass, is a crucial component of any watch, protecting the delicate movement from damage. The Rolex Submariner, famed for its ruggedness and water resistance, utilizes a crystal specifically designed to withstand the pressures encountered during diving. The type of crystal used varies depending on the age and model of the Submariner.
* Acrylic (Plastic) Crystals: Found in vintage Submariners, these crystals are relatively softer and more prone to scratching than sapphire. However, they are generally less expensive to replace. Their flexibility also makes them slightly more forgiving in impacts, although severe damage can still necessitate replacement.
* Sapphire Crystals: Modern Submariners predominantly feature sapphire crystals, renowned for their exceptional scratch resistance and durability. Sapphire is significantly harder than acrylic, making it highly resistant to scratches. However, while less susceptible to scratches, a sufficiently strong impact can still cause chipping or fracturing. The superior hardness also means it's more challenging to work with during replacement.
The Rolex sapphire crystal, in particular, is a precision-engineered component. As mentioned, it often features a subtle groove cut into its edge, which is crucial for proper sealing and water resistance. This groove, along with the precise fit within the watch case, makes replacement a technically demanding task. Improper installation can compromise the watch's water resistance, leading to potentially costly internal damage.
The Process of Replacing a Rolex Submariner Crystal: A Step-by-Step Overview
While the exact steps may vary slightly depending on the specific model and crystal type, the general process involves the following:
1. Case Opening: This is the most critical and potentially risky step. The watch case must be carefully opened without damaging the case itself or the movement inside. This usually requires specialized tools, including a case opener designed for the specific Rolex case construction. Improper technique can easily lead to scratches or dents on the case.
2. Crystal Removal: The old crystal needs to be carefully removed. For acrylic crystals, this might involve using a specialized crystal press or a combination of tools to gently lift the crystal from its bezel. Sapphire crystals, due to their tighter fit and often the presence of the aforementioned groove, typically require even more precision and specialized tools. Excessive force can easily lead to damage.
3. Bezel Removal (if necessary): Depending on the watch model and the method employed by the watchmaker, the bezel might need to be removed to provide easier access to the crystal. This requires specialized tools and careful handling to avoid scratching the bezel or damaging the bezel insert.
4. Crystal Installation: The new crystal must be precisely aligned and seated. For sapphire crystals, this is particularly crucial due to the groove and the need for a perfect seal. The groove needs to align properly with the case, and the crystal must be seated evenly to ensure proper water resistance.
