Gather the necessary tools

Before you begin, gather all the necessary tools to ensure a smooth and efficient repair process. Follow the steps below:

  1. Obtain a small screwdriver: This tool will be used to remove the screws holding the watch’s back cover in place. Ensure that the screwdriver is small enough to fit into the screws without causing damage.
  2. Acquire a soft cloth: The soft cloth will be used for cleaning and wiping any dust or debris that may have accumulated inside the watch. It is important to use a soft cloth to avoid scratching or damaging the watch’s surface.
  3. Get a replacement battery: Make sure you have a replacement battery that is compatible with your watch model. Check the specifications of your watch or consult the manufacturer to ensure you have the correct battery type.

By gathering these essential tools before you begin the repair process, you will be fully prepared to make the necessary adjustments to your watch.


Prepare your workspace

  • Choose a clean and well-lit area for your watch workspace.
  • Ensure that you have a stable surface where you can work comfortably.
  • Find a spot with good lighting to avoid any potential damage or loss of small watch parts.

Remember, a clean and well-lit workspace will help you work efficiently and prevent any unnecessary mishaps when working on your watch.


Remove the watch band

To remove the watch band, start by locating the small spring bars or screws that connect the band to the watch case. Carefully examine the sides of the band to find these attachment points. Once you have identified them, grab a spring bar tool or a small screwdriver. Use the tool to gently remove the bars or screws by inserting the tool into the small holes or notches provided. Apply slight pressure while twisting the tool, allowing the bars or screws to come loose. Once they are fully detached, you can easily separate the watch band from the watch case.


Open the watch case

To open the watch case, follow these steps:

  • Unscrew the case back: If your watch has a screw-down case back, look for notches or grooves on the case back. Use a case opening tool with the correct size to fit into these notches, and turn it counterclockwise to unscrew the case back. Examples of watches that may require unscrewing the case back include diving watches like the Rolex Submariner or the Omega Seamaster.
  • Use a case opener tool: Some watches have a case back that is pressed or snapped onto the case. In this case, you will need a case opener tool to pry open the case back. Place the case opener blade or knife under the lip of the case back and gently apply pressure to lift it. Be careful not to scratch or damage the watch. Examples of watches that may require a case opener tool include certain Seiko models or Timex watches.

Remember, it is crucial to follow the manufacturer’s instructions or consult the watch manual for your specific watch model if you are unsure about the opening mechanism. Opening the watch case incorrectly can lead to damage or voiding the warranty.


Remove the old battery

  1. Open the case. Gently pry open the case using a tool or your fingers, being careful not to damage any parts. Once the case is open, you will have access to the internal components.
  2. Locate the old battery. Inside the case, you will find the old battery positioned in a designated compartment. Take a moment to identify its location, ensuring you can easily access it.
  3. Carefully remove the battery. Using a pair of tweezers or a small tool, grip the old battery firmly but gently. Pull it out of its compartment, making sure to avoid any excessive force that could potentially damage the battery or surrounding components.
  4. Take note of the battery details. As you remove the old battery, observe its model or reference number. This information is crucial for identifying the correct replacement battery, ensuring compatibility and optimal performance.

Remember to handle the old battery with care, following proper disposal procedures to protect the environment and prevent any potential hazards.


Clean the battery compartment

To clean the battery compartment before inserting a new battery, follow these steps:

  • Gather a soft cloth or a cotton swab and the new battery.
  • Open the battery compartment by removing the cover or sliding it open.
  • Carefully inspect the compartment for any dust, dirt, or corrosion.
  • If there is dust or dirt, gently wipe the inside of the compartment using the soft cloth.
  • If there is corrosion, dip the cotton swab in vinegar or lemon juice and gently scrub the affected area.
  • Make sure to remove any residue from the compartment.
  • Once the compartment is clean, insert the new battery according to the correct polarity.
  • Close the battery compartment securely.Example: Before inserting the new battery into your TV remote, use a soft cloth to wipe away any dust or dirt that may have accumulated inside the battery compartment. This will ensure proper contact between the battery and the device, prolonging its lifespan and improving performance.

Insert the new battery

Take the replacement battery and carefully insert it into the battery compartment, ensuring that the positive and negative terminals align correctly with the watch’s contacts. To do this, follow these steps:

  1. Hold the replacement battery by its edges, making sure not to touch the terminals.
  2. Locate the battery compartment on the back of the watch.
  3. Orient the replacement battery so that the positive (+) and negative (-) terminals match the corresponding markings inside the battery compartment.
  4. Gently place the replacement battery into the compartment, making sure it sits securely in its designated space.
  5. Press down lightly on the battery to ensure proper contact between the terminals and the watch’s contacts.
  6. Once the battery is in place, carefully close the battery compartment cover, making sure it is securely fastened.

For example, if the positive terminal on the replacement battery has a “+ ” symbol, make sure it matches the “+” marking in the battery compartment. Similarly, if the negative terminal has a “- ” symbol, align it with the corresponding “-” marking inside the compartment. By following these instructions, you will successfully insert the new battery into your watch.


Close the watch case

If you had to unscrew the case back, grab a case opener tool or use your fingers to tightly screw it back into place. Ensure that the case is securely closed and properly fastened to prevent any water or dust from entering the watch. For example, if you used a case opener tool, insert the tool into the slots on the case back, apply gentle pressure, and rotate it counterclockwise to remove the back. To close the case, place the case back onto the watch case, aligning the notches or grooves, and use the case opener tool to rotate it clockwise until it is tightly closed.


Reattach the watch band

To reattach the watch band, first line up the spring bars or screws with the holes on the watch case. Then, carefully position the watch band over the bars or screws. Use a spring bar tool or a small screwdriver to secure the bars or screws in place. Ensure that the band is securely fastened and test it by gently tugging on it to make sure it is properly attached.

Step-by-Step Guide to Operating Your Waterproof Watch

  • Make sure the watch is properly sealed: Before using a waterproof watch, ensure that the crown (the small knob used to set the time) is pushed in and screwed down tightly. This ensures that the watch is properly sealed and prevents water from entering
  • Check the water resistance rating: Different waterproof watches have varying degrees of water resistance. It is important to check the water resistance rating of your watch to understand the depth and pressure it can withstand. This information is usually provided by the manufacturer
  • Avoid extreme temperature changes: Temperature changes can cause the metal parts of a watch to expand or contract, potentially compromising the water resistance. To prevent this, avoid exposing your waterproof watch to drastic temperature changes, such as jumping into a hot tub or showering with very cold water
  • Clean and rinse after exposure to saltwater: If you plan on using your waterproof watch while swimming in saltwater, it is important to clean it thoroughly afterwards. Rinse the watch under cool, running water to remove any salt residue that may cause corrosion
  • Regular maintenance and battery changes: Like any other watch, a waterproof watch requires regular maintenance. Ensure the gaskets and seals are inspected periodically to ensure they are in good condition. Also, keep an eye on the battery life and have it changed by a professional when needed to maintain water resistance
