What You'll Learn
Preventing damage to the watch movement
Changing a watch battery is a simple task, but it requires careful attention to avoid damaging the watch movement. The watch movement refers to the inner workings of the watch, which can be affected by dirt, oils, or grease from your fingers. Before attempting to remove or replace the battery, it is crucial to understand the potential risks and take the necessary precautions to protect the delicate components of the watch.
One important precaution is to use plastic finger cots or gloves when handling the watch movement. This creates a protective barrier, preventing any natural oils or dirt on your fingers from transferring to the watch and causing damage. It is also recommended to place the watch on a soft fabric with the face down to avoid scratching the surface during the process.
Additionally, it is essential to correctly identify the type of watch back your timepiece has—either a screw back or a snap back. This distinction is important because it determines how you will open the watch case. For a snap back, a tiny screwdriver is used to fit into the hole in the back case, and the case back is twisted out. For a screw back, the correct type and size of screwdriver must be used to avoid damaging the watch case.
When removing the old battery, it is crucial to pay attention to its orientation to ensure the new battery is installed in the same manner. Using a screwdriver, gently loosen the battery from its place and carefully lift it out with your fingers or a pair of tweezers. Be cautious not to let the screwdriver touch other parts of the watch, as this could affect the watch movement. Once the battery is removed, take note of the battery number or any markings to ensure you have the correct replacement.
After installing the new battery, ensure it is secured properly and positioned underneath the tiny flap or plastic movement ring designed to hold it in place. Finally, before closing the watch case, verify that the watch is functioning correctly. If the watch is working as expected, carefully replace the plastic components, such as the white plastic bracket or the rubber gasket, and close the case back according to its type, either by snapping or screwing it into place.

Protecting the watch from dirt, oils, and grease
When replacing a watch battery, it is important to protect the watch from dirt, oils, and grease. Before beginning the process, put plastic finger cots on your fingers to prevent any dirt, oils, or grease on your fingers from damaging the inner workings of the watch. Additionally, when removing the old battery, be careful not to let your screwdriver touch other parts of the watch as this could affect the watch movement.
The plastic components inside a watch case, such as the plastic movement ring and the white plastic bracket, serve a similar purpose in protecting the watch's inner workings. The plastic movement ring keeps the watch movement from moving within the watch case. This ring should be placed back in position after replacing the battery to ensure the watch functions properly.
The white plastic bracket, which sits above the battery, should be gently removed with a screwdriver when replacing the battery. Once the new battery is installed, the bracket is placed back in its original position to secure the battery in place. This bracket helps to protect the battery and the watch movement from damage and ensures the watch functions correctly.
By taking these precautions and carefully handling the watch's internal components, one can effectively protect the watch from dirt, oils, and grease during battery replacement and ensure the watch continues to operate accurately.

Locating the battery number
In some cases, the battery code is printed on the back of the watch, as seen in some Timex watches. However, if the code is not visible externally, you will need to open the watch case to locate the battery number. It is important to exercise caution during this process to avoid damaging the watch movement.
Once the back of the watch case is open, it is recommended to wear plastic finger cots to protect the inner workings of the watch from any dirt, oils, or grease on your fingers. With your fingers protected, you can then proceed to locate the battery number on the battery itself.
If you are unable to find the original battery or do not know the code, you can still identify the correct replacement by measuring the hole where the battery fits in the watch. Diameter or thickness measurements can be used to find the closest match for the required battery dimensions. Additionally, for waterproof watches, it is crucial to check the condition and correct seating of the case gasket before refitting the back.

Replacing the plastic movement ring
The plastic movement ring in a watch is an essential component that keeps the watch's internal components secure and prevents them from moving within the case. Removing and replacing this plastic ring requires careful handling to avoid damaging the delicate watch mechanism. Here is a step-by-step guide to replacing the plastic movement ring:
Step 1: Open the Watch Case
Before beginning any work on the watch, it is crucial to protect the watch movement from dirt, oils, or grease from your fingers. Put on plastic finger cots to cover your fingers, ensuring that you do not touch the watch movement directly with your bare fingers.
Step 2: Identify the Plastic Ring
Locate the plastic movement ring inside the watch case. It is typically placed around the watch movement to keep it in place. The ring may be black or coloured differently, depending on the watch model.
Step 3: Remove the Plastic Ring
To remove the plastic movement ring, you can use tweezers to gently pull and pry it away from the movement. Be cautious and gentle during this step, as plastic is brittle and can break easily. Focus on prying the plastic ring without stressing or damaging the date ring or other nearby components.
Step 4: Clean and Prepare the Area
Before installing the new plastic movement ring, ensure that the area is clean and free of any debris or residue. Use a clean, pointed tool, such as a small, precisely ground Phillips-head screwdriver, to gently remove any dirt or grime that may be present. Be careful not to damage any other components during this cleaning process.
Step 5: Install the New Plastic Ring
Obtain a new plastic movement ring that is specifically designed for your watch model. Carefully place the new ring around the watch movement, ensuring it is secure and properly aligned. Check that the ring is not obstructing any other components, such as the date dial or calendar system.
Step 6: Reassemble the Watch
Once the new plastic movement ring is in place, carefully reassemble the watch case. Ensure that all components are properly aligned and secured before closing the case. Be cautious not to sandwich any plastic components between plates or under/over jumpers during reassembly, as plastic can deform more easily than metal.
Step 7: Final Checks
After reassembling the watch, perform final checks to ensure that the watch is functioning correctly. Check the date display to ensure that the date ring is working properly. Test the watch for time accuracy and water resistance, if applicable.
By following these steps, you can successfully replace the plastic movement ring in your watch. Remember to work with caution and precision to avoid damaging the delicate watch mechanism during the replacement process.
