How to change the battery in a Seiko watch

Battery maintenance is crucial for Seiko watches to ensure their longevity and accuracy. Seiko watches use a battery-powered quartz movement, which relies on a tiny battery to keep the watch ticking accurately. A dead battery can cause the watch to stop running, leading to inaccurate timekeeping and potential damage to the movement. Therefore, it is essential to replace the battery periodically to keep the watch running smoothly and prevent any damage to the movement.


Knowing how to change the battery in your Seiko watch is essential because it can save you time and money. Instead of taking your watch to a professional for a battery replacement, you can do it at home. Additionally, knowing how to change the battery allows you to do so promptly when needed, preventing any downtime for your watch. It also helps you to become more familiar with your watch and its maintenance, ensuring its longevity.


To change the battery in a Seiko watch, you will need a few essential tools, including a small Phillips head screwdriver, a pair of tweezers, and a replacement battery of the correct size. It is essential to use the correct battery size and type, as the watch’s manufacturer recommends, to ensure proper functioning. You may also need a soft cloth or mat to protect the watch from scratches during the battery replacement.

Preparing for the Task

If you’re planning to change the battery in your Seiko watch yourself, here are some steps to follow:

Removing the back case of the Seiko watch:

To access the battery compartment, you need to remove the back case of your Seiko watch. Use a small screwdriver to unscrew the screws holding the back case in place. If your Seiko watch has a snap-on back case, use a case opener tool to gently pry the case off. Be careful not to scratch the watch’s surface or damage the case’s back gasket, which keeps the watch water-resistant.

Identifying the type of battery your Seiko watch requires:

Before purchasing a replacement battery, you need to identify the type and size of the battery your Seiko watch requires. Look for the battery size and type printed on the old battery, or check the watch’s manual for this information. Buy a battery that matches the recommended specifications to ensure optimal performance.

Purchasing a compatible battery:

Purchase a compatible battery from a reputable supplier online or at a watch shop. Look for a high-quality battery from a reliable brand to ensure longevity and accuracy.

Tools required for the task:

In addition to the replacement battery, you will need a small Phillips head screwdriver, a pair of tweezers, and a soft cloth or mat to protect the watch’s surface during the battery replacement process.

Preparing your workspace:

Choose a clean, well-lit workspace with a flat surface to work on. Make sure you have all the necessary tools and materials within reach. Use a watch repair mat or cloth to prevent small parts from rolling away or getting lost during battery replacement. Take your time, be patient, and work carefully to avoid damaging your Seiko watch.
