Fossil Watch Battery Replacement Guide

In this guide, we will explain how to replace a Fossil watch battery. It does require some tools and a steady hand. Make sure to work very carefully to prevent additional damage to your watch.

If you’d prefer to leave the battery replacement to the experts, many opt to use our Fossil mail-in watch battery replacement service. You can request a free, printable shipping label to mail your watch to our service center.

If you feel comfortable performing the process on your own, follow the steps below on how to change a Fossil watch battery.

1. Open the Back of a Fossil Watch

First, we will need to remove the back of your Fossil. Fossil watches generally have a screw case, a slot case, or a hinge case.

If your Fossil watch is secured with screws, simply unscrew the back plate with a screwdriver. If there is a slot in the center, you should be able to twist it open by inserting a coin and turning.

If there are no screws or slots visible, it’s likely a hinge. In this case, we recommend using a common watch back opener. Locate your watch’s hinge on the back case. It will look like a small indentation along the outer ring of the case. Place the edge of your tool underneath this backing hinge, and lift.

2. Find the Battery Size of a Fossil Watch

Now you’ll be able to view the inner components of the watch. With a magnifying glass, see what type of battery powers your Fossil. Fossil battery replacement sizes are usually a 2430 (CR2430), 371 (SR920SW), or 377 (SR626SW).

We recommend using a quality battery brand such as Duracell or Renata. At our repair center, we stock all three battery sizes – as well as dozens of other sizes.

3. How to Replace the Watch Battery in a Fossil

Inside certain Fossil watch models, there is a clip over the battery that holds the cell in place. The clip may be screwed or pinned over the top. If there is a clip, carefully remove or loosen it.

Once the battery is accessible, insert your tool of choice into the opening. Slowly ease the old battery from the casing. Unpackage your new battery and replace.

Gently press the new battery into position, and reclip if necessary. Make sure not to nick any other mechanisms inside the watch, as this can cause more serious, auxiliary damage.

Before closing the back cover, make sure the watch is functional. If it is not, you may have installed the battery incorrectly, or there may be additional damage to the watch. If you cannot get the watch working properly, you can mail it to our service center for a complete inspection.

4. Secure the Cover Back on the Fossil Watch

Now that your watch is keeping time and functioning properly, you can close the case. If you have a slot or screw case, simply screw the case back into place. If you have a hinge case, we recommend a watch press set. Most come with an assortment of sizes that allow you to fit the press to your specific watch case.

You can attempt to secure the case back with your thumbs. You’ll need to apply a significant amount of pressure. If you can successfully press it back into place, you should feel a light click.
