Changing the Glass for a Replacement

One common issue with watches, including the Rolex Lady Datejust, is a broken or scratched crystal. The crystal is the transparent cover that protects the dial and hands of the watch while allowing you to read the time. Replacing the crystal requires careful handling and the use of specific tools.

To change the glass on a Rolex Lady Datejust, follow these steps:

1. Begin by removing the bracelet or strap from the watch to ensure easy access to the crystal.
2. Obtain a crystal replacement suitable for the Lady Datejust model. It is crucial to get the correct size and shape to ensure a proper fit.
3. Place the watch face down on a soft cloth or watch repair mat to protect its surface.
4. Use a case knife or a specialized crystal lift tool to gently pry off the old crystal. Apply even pressure around the edges until the crystal pops out.
5. Clean the area around the bezel and ensure there are no remnants of the old crystal.
6. Carefully align the replacement crystal with the bezel and press it into place using your thumbs. Make sure it sits flush and level.
7. Inspect the crystal for any gaps or misalignment. If necessary, repeat the process until the replacement crystal is perfectly fitted.

Using the Correct Tools for Removing the Bezel

Before you can access the crystal and replace it, you need to remove the bezel that holds it in place. The bezel is the ring-like component surrounding the crystal. To remove the bezel without causing damage, it is crucial to use the appropriate tools.

For Rolex Lady Datejust models, you will need the following tools:

1. A case-back opener: This tool, specifically designed for opening watch cases, helps you remove the back cover of the watch.
2. A bezel removal tool: A bezel removal tool allows you to safely and precisely lift the bezel without scratching or damaging the watch’s surface. There are various types of bezel removal tools available, so ensure you choose one suitable for your Lady Datejust model.
3. Tweezers: Tweezers are useful for holding small components such as screws or springs during the repair process. Use a pair with fine tips for delicate tasks.
4. A watch repair mat: A soft, non-slip mat helps protect the watch’s surface during repairs and prevents any small components from rolling away.

Removing the Old Crystal and Fitting the New Glass

Once you have removed the bezel, it is time to remove the old crystal and fit the new glass. This task requires patience and focus to ensure the watch’s integrity is maintained. Follow these steps:

1. With the bezel removed, gently lift the old crystal using your fingers or a crystal lift tool if required. Take care not to exert excessive force that could damage the watch.
2. Inspect the area around the bezel for any dirt or debris. Use a microfiber cloth or a brush specifically designed for watch cleaning to remove any particles.
3. Take the new replacement crystal and align it carefully with the bezel.
4. Apply even pressure around the edges of the crystal until it fits snugly into the bezel. Avoid using excessive force or tapping the crystal as it may crack or break.
5. Once the new crystal is securely in place, give the watch a gentle shake to ensure it is properly seated and does not move within the bezel.

Using a Glass Press to Put the Bezel Back On

After successfully fitting the new crystal, it is time to put the bezel back on. To ensure a secure fit, it is advisable to use a glass press tool. This tool exerts even pressure on the bezel, minimizing the risk of damage during installation.

Follow these steps to use a glass press:

1. Place the watch face down on a non-slip surface, ensuring the crystal is protected.
2. Position the bezel carefully on top of the crystal, aligning it with the watch case.
3. Gently apply downward pressure on the bezel using the glass press tool. Make sure the pressure is evenly distributed across the entire bezel to avoid misalignment or damage.
4. Inspect the watch and ensure the bezel is securely in place. Verify that it sits flush with the case and does not wiggle or move when pressed.

Regulating the Watch and Adjusting the Screws for Rate

Once the crystal and bezel are successfully replaced, it is crucial to regulate the movement of the watch to ensure accurate timekeeping. Regulating a watch involves adjusting the screws or weights on the balance wheel, which directly affects its rate and precision.

To regulate the Rolex Lady Datejust, follow these steps:

1. Open the case back using a case-back opener tool, taking care not to damage the watch’s finish.
2. Locate the balance wheel inside the watch. The balance wheel is a wheel-like component that oscillates back and forth, controlling the timekeeping accuracy.
3. Identify the regulating screws on the balance wheel. These screws control the balance wheel’s rotation speed and can be adjusted to fine-tune the watch’s accuracy.
4. Using a screwdriver or a specialized regulating tool, make small adjustments to the regulating screws. To increase the watch’s rate, turn the screws clockwise. To decrease the rate, turn them counterclockwise.
5. Make incremental adjustments and test the watch’s accuracy by wearing it or using a timegrapher, which measures the precise rate of a watch. Repeat the process until the desired accuracy is achieved.

Finalizing the Watch and Comparing its Size

After you have successfully replaced the crystal, fitted the new glass, and regulated the watch’s movement, it is essential to give the entire timepiece a thorough inspection. Ensure all components are securely fastened, and there are no signs of damage or misalignment.

Additionally, take the opportunity to compare the size of your Rolex Lady Datejust to other watches in your collection or watches you are considering purchasing. Compare the case diameter, thickness, and overall proportions to determine if it suits your personal preferences and style.
