Crystal Clarity: How to Replace the Glass of Your Audemars Piguet Royal Oak

Over time, your Audemars Piguet Royal Oak's glass may become scratched or damaged, affecting its overall appearance. Replacing the glass is essential to restore its crystal clarity and keep your timepiece looking its best. In this guide, we will walk you through the step-by-step process of replacing the glass of your Audemars Piguet Royal Oak.

1. Gather the Required Tools

Before you begin, ensure you have the necessary tools for the glass replacement:

  • A soft cloth or watch bracelet holder to protect the watch's finish.
  • A watch case opener or a case back removal tool.
  • A case knife or a case back press.
  • A glass crystal specifically designed for your Audemars Piguet Royal Oak model.

2. Safety Precautions

Working on your watch requires care and precision. Ensure you work on a clean and clutter-free surface to avoid losing small parts during the process. Additionally, handle your Royal Oak with care to prevent any accidental damage.

3. Opening the Case Back

To access the glass, you need to remove the case back. Use a watch case opener or a case back removal tool to gently open the case back. Be cautious not to scratch or damage the case back or the surrounding area.

4. Removing the Old Glass

Once the case back is removed, carefully examine the old glass and identify how it is secured in place. Most watch glasses are held by a plastic gasket or a metal ring. Use a case knife or a case back press to carefully remove the gasket or ring.

5. Inserting the New Glass

Place the new glass crystal into the designated area, ensuring it fits securely. For watches with a plastic gasket, gently press the gasket into place around the glass. For watches with a metal ring, use the case back press to apply even pressure and secure the glass.

6. Closing the Case Back

Once the new glass is in place, reattach the case back by carefully aligning it with the case and using the case back press or a case back removal tool to close it securely. Ensure that the case back is properly sealed to maintain the watch's water resistance.

7. Polishing and Cleaning

To achieve a flawless finish, carefully polish the exterior of the watch using a soft cloth. Be gentle to avoid scratching the case or the newly replaced glass. Clean the watch thoroughly to remove any dust or fingerprints.


Replacing the glass of your Audemars Piguet Royal Oak requires attention to detail and precision. By following this step-by-step guide and using the appropriate tools, you can achieve crystal clarity and restore the flawless appearance of your iconic timepiece.

If you are unsure about performing the glass replacement yourself, it is recommended to seek assistance from an authorized Audemars Piguet service center or a professional watchmaker to ensure a successful and safe glass replacement. With the glass replaced, your Audemars Piguet Royal Oak will once again shine as an enduring symbol of elegance and horological excellence.
