How do you fit a watch battery?

Published in Watch Repair 2 mins read

Fitting a watch battery typically involves removing the old battery and snapping a new one into place using your fingers or thumbs.

Here's a breakdown of the process, though it's crucial to note that specific watch models may have slightly different procedures:

  1. Open the Watch Back: Watch backs vary. Some have small indentations that can be pried open with a small tool. Others require unscrewing. A specialized watch case opener tool is often used.
  2. Locate and Remove the Old Battery: Once the back is off, identify the old battery. It's usually held in place by a small metal clip or bracket. Use a non-metallic tool (like plastic tweezers) to gently release the clip and remove the old battery. Important: Avoid using metal tools to prevent short-circuiting the battery.
  3. Identify the Correct Replacement Battery: Note the battery's code (e.g., CR2032, SR626SW). Make sure you get the exact replacement type.
  4. Insert the New Battery: Carefully place the new battery in the same orientation as the old one (usually with the positive side facing up, but check the markings).
  5. Secure the Battery: Reattach the metal clip or bracket to hold the new battery in place. You should often hear a "snap".
  6. Close the Watch Back: Align the watch back properly and either press it firmly into place (for snap-on backs) or screw it back on tightly (for screw-on backs).
  7. Set the Time: Once the new battery is installed and the watch is closed, set the correct time.

Safety Precautions:

  • Always use the correct replacement battery type.
  • Avoid using metal tools that could short-circuit the battery.
  • If you're not comfortable performing the battery replacement yourself, take the watch to a professional jeweler or watch repair shop.
