Replacing the mirror (or crystal) of an Omega watch requires both technical skill and precision. Whether your Omega has sustained damage from a scratch, crack, or other form of wear, or you simply want to upgrade the crystal to a higher-quality material, it’s important to follow a structured process. This guide provides step-by-step instructions, along with helpful tips, tools, and techniques, for replacing the watch mirror of your Omega watch.
Introduction: Understanding Watch Crystals
A watch crystal, often referred to as the “mirror,” is the transparent cover that protects the dial of the watch. It plays an essential role in shielding the movement of the watch from dust, water, and physical damage. Omega watches typically feature either sapphire crystal, hesalite, or mineral glass, each with distinct properties and benefits.
Types of Watch Crystals
Sapphire Crystal: Known for its hardness and scratch resistance, sapphire is one of the most durable materials used in watch crystals today. It is a synthetic crystal made from a specially engineered form of aluminum oxide.
Hesalite Crystal: A type of acrylic, hesalite is more common in vintage models and is often chosen for its lightweight nature and resistance to shattering. It is more prone to scratching but can be polished easily to restore clarity.
Mineral Glass: This is another commonly used material for watch crystals. While it is harder than acrylic, it doesn’t have the scratch resistance of sapphire. However, it is still a good choice for durability.
Step 1: Assessing the Damage to the Crystal
Before proceeding with replacing the crystal, carefully assess the damage to your Omega watch. Cracks, chips, deep scratches, or hazy areas are the most common signs that your crystal may need replacing.
Cracks or Breaks: If the crystal is cracked or broken, it will need to be replaced for both functional and aesthetic reasons. A cracked crystal can compromise the water resistance of the watch and may also lead to further damage to the movement inside.
Scratches: If the scratches are light, they might be able to be polished out (for materials like hesalite). However, deep scratches or scuff marks usually require replacement.
Haze or Cloudiness: Over time, some materials (especially hesalite) may develop a hazy appearance due to exposure to sunlight, chemicals, or environmental elements. This issue is more aesthetic than functional but still warrants replacing the crystal if it bothers you.
Step 2: Gathering the Necessary Tools and Materials
Replacing the watch mirror of an Omega watch requires several specialized tools. It is important to gather the necessary equipment before beginning the replacement process. Here’s a list of tools you will need:
Tools Needed:
Case Back Opener: If your Omega watch has a screw-down case back, a case back opener is essential for removing the back cover.
Watch Crystal Press: This tool is used to install the new crystal, ensuring it sits properly in place without damaging the case.
Screwdrivers: A set of precision screwdrivers will be necessary to remove any screws holding the crystal in place.
Crystal Lift: This tool is useful for removing the damaged crystal safely from the watch case.
Tweezers: Fine-tipped tweezers are helpful when handling small parts like gaskets or the new crystal.
Replacement Crystal: Ensure you select the correct replacement crystal for your specific Omega model. You can consult Omega’s official parts catalog or an authorized dealer for the correct part number.
Gasket: A new gasket may be required to ensure water resistance. It is best to replace the gasket whenever you are replacing the crystal.
Microfiber Cloth: Use a microfiber cloth to keep the watch clean and free from scratches during the process.
Watch Holder: A watch holder or stand is recommended to keep the watch secure while you work on it.
Step 3: Removing the Damaged Crystal
This is one of the most delicate steps in the process, as removing the old crystal requires careful handling to avoid damaging the watch case. Below is a detailed procedure for removing the old crystal:
Procedure for Removing the Old Crystal:
Prepare Your Workspace: Set up a clean, well-lit workspace with all tools laid out. Ensure that you have a soft, cushioned surface to place your watch on during the process.
Remove the Case Back: Use the case back opener to carefully remove the back of the watch. Omega watches can have different types of case backs, such as screw-down backs or snap-on backs. Take extra care when removing the back so as not to scratch the watch.
Remove the Movement: In most cases, you will need to remove the movement from the case. Use a precision screwdriver to unscrew any screws holding the movement in place. Gently lift the movement out of the case, taking care to avoid damaging the hands or dial.
Remove the Crystal: To remove the damaged crystal, you will use a crystal lift or a similar tool to pry it off. Apply gentle but firm pressure to lift the crystal out of its seating. Be careful not to damage the bezel or the case during this step.
Step 4: Installing the New Crystal
Once the old crystal is removed, it’s time to install the new one. This process requires careful alignment to ensure that the crystal fits securely and correctly.
Procedure for Installing the New Crystal:
Check the Fit of the New Crystal: Before proceeding, ensure that the new crystal matches the size and shape of the original. Place the new crystal into the bezel, and make sure it fits snugly.
Insert the Gasket: Apply a new gasket (if necessary) around the perimeter of the crystal. The gasket ensures a secure fit and helps maintain water resistance.
Press the New Crystal into Place: Using a crystal press, carefully press the new crystal into the case. Ensure that the crystal is seated evenly and securely. It should be flush with the bezel, with no gaps or irregularities.
Step 5: Reassembling the Watch
With the new crystal in place, it’s time to reassemble your Omega watch. This involves carefully placing the movement back into the case, securing the case back, and ensuring everything is properly aligned.
Procedure for Reassembling the Watch:
Insert the Movement: Place the movement back into the watch case. Make sure it is aligned properly with the case and the dial.
Secure the Movement: Use the precision screwdrivers to secure any screws that hold the movement in place.
Replace the Case Back: Carefully screw the case back onto the watch. Make sure the case back is tightly sealed to maintain the water resistance of the watch.
Step 6: Testing the Watch
Once your Omega watch is reassembled, it’s important to test its functionality. Here are a few tests you should perform:
Visual Inspection: Check that the crystal is properly seated and that there are no gaps between the crystal and the case.
Water Resistance Test: If your Omega is water-resistant, test the seal to ensure that it maintains its ability to resist water. You may want to have this done professionally if you’re unsure.
Movement Check: Test the movement of the watch to ensure it is functioning properly.
Conclusion
Replacing the watch mirror of an Omega watch is a task that requires patience, precision, and the right tools. By following the steps outlined in this guide, you can replace the damaged crystal and restore your watch to its original beauty. If you’re not confident in your ability to complete the replacement, consider consulting a professional watchmaker to ensure the job is done correctly.
