How to Change a Watch Battery Safely at Home
Changing a watch battery might seem intimidating, but with a little patience and the right tools, it's a simple task you can do at home. Whether your watch has stopped ticking or is showing signs of a dying battery (slow movement, fading display), this guide from JF Jewellers walks you through the process step by step.
⚠️ Note: If your watch is water-resistant, high-end, or sentimental, we always recommend professional servicing to avoid damage.
Tools You’ll Need:
Watch case opener (knife or case wrench, depending on case type)
Non-metal tweezers
Precision screwdriver set
Soft cloth or matt
Replacement battery (correct size for your watch)
Optional: Watch holder or case clamp
Step-by-Step Guide:
1. Prepare Your Workspace
Find a clean, well-lit space. Lay down a soft cloth to prevent scratches to your watch.
2. Open the Watch Case
Watches typically have two types of case backs:
Snap-off case: Use a case knife or thin blade to gently pry the back open at the small notch.
Screw-back case: Use a case wrench or rubber ball to unscrew it counterclockwise.
Be gentle! Excess force can scratch or damage the case.
3. Locate and Remove the Old Battery
Once the case is open, you’ll see the battery held in place by a clip or arm.
Use a plastic tool or non-metal tweezers to carefully lift the battery out.
Take note of the battery’s code (e.g., SR626SW, CR2016) so you can buy the correct replacement.
4. Insert the New Battery
Slide the new battery in using plastic tweezers to avoid static damage.
Ensure it's properly seated and the clips are secure.
If your watch doesn’t start ticking immediately, give it a few seconds or gently tap the case.
5. Test the Watch
Before sealing it back up, check if the hands are moving or digital display is working.
6. Close the Case Back
For snap-off cases, press down firmly with your thumbs or a case press.
For screw-back cases, re-tighten gently with a wrench or your palm using a rubber ball.
Ensure the back is secure to maintain dust and water resistance.
Tips to Keep in Mind:
Don't touch the new battery with bare hands – oil and moisture can reduce battery life.
Use the correct battery type – always match the replacement to your old battery.
Change batteries every 1–2 years to avoid leakage and corrosion.
