Complete Guide to Opening Screw-Down (Notched) and Clip-On Back Watches
Opening a watch can seem like a daunting task, especially when it comes to models with a notched or clipped back. However, with the right tools and a little precision, you can easily do it yourself. In this detailed guide, we explain how to open a watch with a notched and clipped back, step by step.
1. Understanding the types of funds: Notched and Clipped
-
Watch with notched screw-down back : The back of the watch has notches all around it, which can be gripped with a special tool. This type of back is often used for waterproof watches, as it ensures good water resistance.
-
Clip-on back watch : In this case, the back is held in place by a clip-on mechanism. There are no screws or notches to manipulate, but a small space to lever and pop the back off without damaging the watch.
2. Necessary tools
Before you begin, you will need some specific tools to avoid damaging the watch or its internal components:
- A notched back opening tool : A tool with jaws, key or case opener with jaws specially designed to grip the notches and unscrew the back.
- A small pry tool (for clip-on cases) : A plastic or soft metal tool to pry open the watch without scratching the case.
- A flat or cross-head screwdriver : If screws are present (less common for notched or clipped bottoms).
- Anti-magnetic tweezers : For handling internal components without risk.
- A soft cloth : To clean the watch before and after opening.

3. Prepare a clean and stable work space
Choose a flat, clean, well-lit surface to work on. You can use a watch mat or small box to rest the watch on, which will prevent scratches and loss of small parts.
4. How to open a watch with a notched back
Steps:
-
Place the watch face down : Position the watch with the back facing you. Make sure the dial and hands are protected from accidental pressure.
-
Insert the opening tool into the notches : Use a suitable opening tool, designed specifically to grip the notches of the notched back. Insert it into the notches of the case, making sure it is snug.
-
Turn counterclockwise : Holding the opening tool firmly, gently turn it counterclockwise. This will loosen the bottom. Be patient and avoid forcing if you encounter excessive resistance.
-
Remove the case back : Once loosened, you can remove the case back by hand. Be gentle so as not to scratch or damage the case. You should have direct access to the internal components.
5. How to open a watch with a clipped back
Steps:
-
Locate the pry point : The clipped back is held in place by internal hooks or clips. You should see a small gap where you can insert a pry tool to open the watch.
-
Insert the pry tool : Use a small plastic or soft metal tool to insert into the pry gap. Be careful not to damage the case by forcing too hard. Light, even pressure should be enough to pop the case back out.
-
Pry gently : As you insert the tool and apply light pressure, you should hear a small “click” indicating that the bottom is free. Be patient and work slowly.
-
Remove the clipped bottom : Once the bottom is open, you can carefully remove it by hand. Be careful not to lose the small clips that hold the bottom in place.
6. Handling the battery and internal components
Once the back is open, you have access to the inside of the watch. If you are replacing the battery, use anti-magnetic tweezers to remove the old battery. Make sure to place the new battery in the correct orientation and check that it is making good contact with the connectors.
7. Close the watch after the procedure
For a watch with a notched back :
- Position the Back Cover : Once you have replaced the battery or made your repairs, carefully replace the notched back cover onto the case.
- Use the opening tool : Turn the tool clockwise to lock the bottom in place. Make sure it is secure without forcing.
For a watch with a clip-on back :
- Replace the bottom : Align the bottom properly with the internal hooks or clips.
- Press firmly : Apply even pressure to properly clip the bottom onto the case.
8. Test the watch
After replacing the case back and reconditioning the watch, check that it is working properly. If you have changed the battery, make sure that the watch restarts properly and that the hand movement is smooth.
9. Cleaning and maintenance
Once the opening and repair are complete, clean the watch to remove any dust, fingerprints, or residue. Use a soft cloth to wipe the case and dial. If you opened a waterproof watch, check the water resistance carefully before wearing it in water.
Additional tips:
- Be gentle and precise : Handling the internal components of a watch requires delicacy. Never force when opening.
- Check the gaskets : If your watch is water-resistant, inspect the gaskets before closing the case. If the gasket is damaged, it is important to replace it to maintain water resistance.
- Test the water resistance : For waterproof watches, after closing the case back, it is recommended to test the water resistance before exposing it to water.
Conclusion
Opening a watch with a notched or clipped back requires the right tools, patience, and a certain amount of precision. If you follow these steps, you can perform maintenance on your watch yourself, such as replacing the battery, while ensuring the safety and functionality of the entire mechanism.
