When your watch stops working, there can be several reasons, but the most common one is usually that your battery needs replacement.
As a brand established in 2012, NAVIFORCE has been committed to providing high-quality, feature-rich, and affordable watches to consumers worldwide.
Also as a watch manufacturer, we understand that battery replacement is a key part of keeping your watch running accurately.
Whether you prefer to replace a watch battery yourself or seek professional service, this comprehensive guide will walk you through how to change battery in a wrist watch from preparation to post-replacement inspection.
How to Determine When a Watch Battery Needs Replacement
Identifying when your watch batteries need replacement is the first step in watch maintenance. When your quartz watch shows the following symptoms, it usually means the battery needs to be replaced:
● The second hand begins to move irregularly, such as jumping only once every few seconds, which is an early sign of low battery power.
● When the watch completely stops running, or special functions (such as timing, backlight) do not work properly, it also indicates that the battery is depleted.
● Some watches are equipped with a low battery indicator, which will remind you to replace the battery through specific movement patterns.
Replacing the battery promptly not only restores normal watch function but also avoids potential leakage problems caused by long-term battery depletion, protecting the delicate movement from damage.
Choosing the Right Watch Battery and Where to Buy
Choosing the right watch batteries for your timepiece is crucial. Common watch battery models include SR626SW (377), SR621SW (364), CR2025, and others.
Battery specifications are usually printed on the old battery or can be found in the watch manual. Choosing a well-known brand battery can ensure stable performance and longer service life. If you are unsure which battery you need, consult the official customer service or refer to the watch manual for accurate information.
Where to buy watch batteries: You can purchase watch batteries at jewelry stores, watch repair shops, electronics stores, or online retailers like Amazon. For specialty batteries, dedicated watch parts suppliers often have the best selection.
Tip: For NAVIFORCE watches, you can find the battery information in the watch specifications from the download area of our official website by entering your watch model number.
Tools Needed for DIY Watch Battery Replacement
If you've decided to learn how to install a watch battery yourself, you may need the following tools:
● Watch case opener tool suitable for your watch type (blade-style opener or appropriately sized screwdriver)
● Anti-static tweezers (for handling the battery)
● Small precision screwdriver set (for removing fixing screws)
● New battery (ensure it matches the original battery specifications)
● Soft lint-free cloth (to protect the watch surface)
● Magnifying glass (to help observe small components)
Having the right tools not only improves operational efficiency but also effectively reduces the risk of damaging the watch.
Make sure to work on a clean, well-lit, and flat work surface, ideally with a soft cloth as a pad to prevent scratching the surface.
Detailed Steps for Watch Battery Replacement:
How to Replace Watch Battery
Step 1: Identify the Watch Case Back Type
First, you need to determine which type of case back your watch uses before attempting to open watch battery compartment. Common case back types include:
● Screw-type case back: Usually has grooves on the edge and requires special tools to unscrew
● Snap-on case back: Secured by clips, needs to be pried open from the edge
● Screw-fixed case back: Fixed by small screws, requires matching screwdriver for removal
Identifying the case back type will help you choose the correct tools and opening method when learning how to open watch battery compartment.
Step 2: Open the Watch Case Back
Based on your watch case back type, use the appropriate method to open it:
For snap-on case backs, insert the case opener or thin blade into the small gap at the edge of the case back and gently pry it up.
To avoid scratching the watch case back, it's recommended to place a layer of plastic film between the tool and the watch.
For screw-type case backs, use a specialized tool or needle-nose pliers (scissors can also work), position the tool in the grooves on the edge of the case back, and turn counterclockwise to open.
For case backs with screw , use an appropriately sized screwdriver to remove all fixing screws, then remove the case back.
Be gentle and careful during operation, avoiding excessive force that could damage the case or internal movement.
● Be careful not to injure yourself when using sharp knives or screwdrivers.
● If you've tried all methods and still cannot open the watch case back, you should find the nearest watch repair shop for professional assistance.
Step 3: Remove the Old Battery
After opening the case back, you will see the watch movement and battery. Learning how to remove watch battery safely is crucial. The battery is usually secured by a small metal clip or spring. Use anti-static tweezers to gently move the securing device and remove a watch battery without damaging other components.
Before removing a watch battery, carefully observe and note the installation direction and position of the battery, especially the positive and negative pole orientation, as this is crucial for correctly installing the new battery.
Also, note the battery model (usually printed on the battery surface) to ensure you purchase the correct replacement battery.
Tip: Watches with dual displays usually have two batteries.
Step 4: Install the New Battery
After you've learned how to remove a watch battery, the next step is understanding how to install a watch battery correctly. Obtain a new battery of exactly the same model as the old one. Before installing the battery, you can gently clean the battery contact points with a cotton swab or soft cloth to ensure there is no oxidation or dust affecting conductivity.
Use tweezers to pick up the new battery and place it according to the installation direction of the old battery, ensuring the correct orientation of the positive and negative poles.
The positive pole (+) of most watch batteries should face up. Gently press the battery into place and ensure that any securing devices (such as metal clips or springs) correctly secure the battery.
Step 5: Check Watch Functionality
Before replacing the case back, turn the watch over and check if the second hand has started running normally. If the watch doesn't start, check if the battery is installed correctly and if the contact points are making good contact.
For multi-function watches, test whether all functions are working normally. Only proceed to the next step after confirming everything is working properly.
Step 6: Reinstall the Case Back
After confirming the watch is working normally, check if the waterproof gasket (if any) is intact and properly positioned. If the waterproof gasket is damaged or deformed, it's recommended to replace it with a new one to maintain water resistance.
Based on the case back type, use the corresponding method to install the case back: snap-on case backs usually just need even pressure to click back into place; screw-type case backs need to be turned clockwise until tight; screw-fixed case backs require reinstallation and even tightening of all screws.
Ensure the case back is securely and evenly installed, which is particularly important for maintaining the watch's water resistance.
Watch Battery Replacement Cost
Although many people can learn how do you replace a watch battery at home,but if your watch has a high water resistance rating, it's recommended to search for the nearest watch repair shop rather than attempting DIY repairs that might void the warranty or reduce water resistance.
A common question is: how much does it cost to replace a watch battery professionally? The watch battery replacement cost varies by region, watch type, and service content. Generally, basic battery replacement services range from $5-25, with higher prices for high-end watches or models requiring special handling.
Common Issues After Battery Replacement and Solutions
Watch doesn't run after battery replacement: Check if the battery is installed in the correct direction, if the battery contact points are clean, and if you are using the correct battery model.
Some watches may require a specific reset procedure, such as pressing a specific button or briefly connecting the battery contact points.
Watch doesn't keep accurate time after battery replacement: It may need adjustment or calibration; consult a professional technician.
Reduced water resistance: Usually caused by damaged or improperly installed waterproof gaskets; replacement gaskets and professional water resistance testing are needed.

As a professional watch manufacturer, NAVIFORCE is committed to providing you with high-quality products and professional maintenance advice.
We hope this guide helps you better understand the watch battery replacement process, from learning how to open watch battery compartments to correctly installing new watch batteries.
