Tools You’ll Need
Before you begin replacing a battery in a watch, you first need to gather these essential tools:
-
A small flat-head screwdriver or watch case opener
-
Tweezers
-
Watchmaker’s knife for snap-off case backs
-
Miniature Phillips screwdriver for screw-down backs
-
Clean microfiber cloth
-
Replacement battery that matches the correct model number
-
Optional: magnifying glass, rubber ball
How to Identify Your Watch Case Back Type (And Open Them)
It is important to know your case back type for safe watch battery replacement. Here are the main types:
-
Snap-off case back
These backs pop open with just slight pressure. You can use a case knife or thin blade to gently lift the back from the notch. It's mostly common in fashion and dress watches. Make sure that you always place the blade in the groove and twist lightly, because forcing it can damage the case.
-
Twist-off case back
These round backs twist off and are typically found on waterproof or sport watches. You’ll need a rubber ball or case wrench for grip. Turn it counterclockwise to loosen. Avoid using any pliers or makeshift tools as they can scratch the watch.
-
Case backs with screws
These are held down by 4-6 tiny screws. You can use a precision Phillips-head screwdriver to remove them carefully. Keep screws in a safe place, as they’re easy to lose. This type is common in watches that have higher water resistance that are used for better sealing.
Step-by-Step Guide to Changing a Watch Battery
Step 1: Prepare your workspace and tools
Lay a soft microfiber cloth on a flat surface and arrange your tools and battery nearby. This is done to prevent scratches and keeps tiny parts from getting lost. Also make sure that your hands are clean and dry or you’re wearing gloves to avoid contaminating internal components.
Step 2: Open the watch case back
Based on the case back type, use the appropriate tool to open it. If screws are involved, carefully unscrew each one and store safely.
Step 3: Carefully remove the old battery
Use non-metal tweezers to lift out the old battery and avoid touching other components. Some batteries are held with clips, so you need to gently unclip before removal. Remember your battery’s position and orientation because that will help during reinstallation and dispose off the old battery responsibly.
Step 4: Clean the battery compartment
Use a dry, lint-free cloth or light blower to remove dust or debris inside the case. Don’t use any liquids while doing it. Cleaning also prevents corrosion buildup from old battery leaks.
Step 5: Insert the new watch battery (how to install a watch battery)
Take the new battery and slide it into the place, matching the correct polarity (usually the "+" side is upward facing). You can do it with the help of tweezers to avoid touching it with your fingers. Double-check that the battery is fit in place without force.
Step 6: Secure the battery and reassemble the watch
If your battery is secured with a clip, then gently snap it back in place. Close the case back or screw it in to snap it shut using your case tool. Make sure that it’s sealed properly, especially if the watch is water-resistant. Check that no other parts are loose as well.
Step 7: Check if the watch is working
Turn the watch over and see if the second hand has started working. If it's not, then press lightly on the battery to ensure contact.
If its still not ticking, then try resetting the movement or consider that the issue may lie deeper and possibly needing professional help.
How to Identify if Your Watch Needs a New Battery
If your quartz watch has stopped ticking, has slowed down, or the second hand skips every few seconds, then it’s likely time for a watch battery replacement.
