How to Replace Your Seiko Watch Battery

Step 1: Gather Your Tools To replace the battery in your Seiko watch, you will need:

• A small screwdriver (usually a Phillips or flathead, depending on the watch case)
• A pair of tweezers
• A new battery (refer to the chart above for the correct type)
• A case back remover tool (optional, but recommended for some models)

Step 2: Open the Watch Case

• If your Seiko watch has a screw-down case back, use the case back remover tool to unscrew it. If it's a snap-on case back, gently pry it off with a small flathead screwdriver.
• Be cautious not to scratch the case or damage any components.

Step 3: Remove the Old Battery

• Locate the battery compartment. Depending on the model, you may need to lift a small clip or lever to access the battery.
• Use tweezers to carefully remove the old battery. Avoid touching the new battery with your fingers to prevent oils from damaging it.

Step 4: Insert the New Battery

• Place the new battery in the compartment, making sure it's positioned correctly according to the positive (+) and negative (-) markings.
• If there is a clip or lever, secure it back in place.

Step 5: Close the Watch Case

• Carefully replace the case back, ensuring it is securely fastened. For screw-down backs, use the case back remover tool to screw it back on.
• Check that the case back is flush with the watch to prevent water damage.

Step 6: Test the Watch

• Set the time and date to ensure the watch is working correctly. If the watch does not start, double-check the battery placement and ensure the case back is properly secured.

Additional Tips

• Always use high-quality batteries from reputable brands to ensure longevity and performance.
• If you are unsure about replacing the battery yourself, consider taking your watch to a professional watchmaker or authorized Seiko service center.
• Regular maintenance can help extend the life of your watch and prevent future issues.
