If you own a Fossil watch, you know how essential it is to keep it ticking smoothly and accurately. Over time, however, even the most reliable watch batteries will run out of power, leaving your timepiece silent and in need of a fresh energy source. Learning how to remove a Fossil watch battery not only saves you a trip to the jeweler but also empowers you to maintain your watch with confidence and care.

Removing the battery from a Fossil watch might seem daunting at first glance, especially given the precision and delicate components involved. Yet, with the right approach and a bit of patience, this task becomes manageable even for beginners. Understanding the general process and the tools required can help you avoid common pitfalls and ensure your watch remains in excellent condition.

This article will guide you through the essentials of battery removal, offering insights into what to expect and how to prepare. Whether you’re looking to replace the battery yourself or simply want to understand the procedure better, gaining a clear overview is the first step toward keeping your Fossil watch running perfectly.

Accessing the Battery Compartment

To remove the battery from a Fossil watch, the initial step involves accessing the back case of the watch. Most Fossil watches feature a snap-off or screw-down case back, and identifying which type your watch has is crucial for proceeding safely.

For snap-off backs, gently inserting a case knife or a thin, flat tool into the small notch on the edge of the case back allows you to pry it open. Apply slow, even pressure to avoid scratching or damaging the watch. For screw-down backs, you will need a case back wrench or a specialized tool designed to fit the notches around the perimeter. Rotate the wrench counterclockwise to unscrew the back.

Take care to work in a clean, well-lit area and consider placing a soft cloth underneath the watch to prevent scratches during the process.

Removing the Old Battery

Once the back cover is removed, locate the battery holder. Fossil watches typically secure the battery with a small clip or a metal strap. It is important to handle these components delicately to avoid damage.

Use a pair of plastic tweezers or a non-metallic tool to lift the battery out of its compartment. Avoid using metal tools as they can cause short circuits or damage the movement. Note the orientation of the battery (which side is facing up), as this will be important when inserting the new battery.

If the battery is held in place by a clip, gently push the clip aside or unscrew any retaining screws before attempting to remove the battery. Keep any screws or clips in a safe place as you will need them during reassembly.

Choosing the Correct Replacement Battery

Identifying the correct replacement battery is vital for the proper functioning of your Fossil watch. Most Fossil watches use standard silver oxide button cells, but the exact model number varies. The battery number is often printed on the battery itself or noted in the watch’s user manual.

Below is a table of common Fossil watch battery types along with their specifications:

Battery Model Diameter (mm) Height (mm) Voltage (V) Common Applications
SR626SW (377) 6.8 2.6 1.55 Quartz watches, including many Fossil models
SR621SW (364) 6.8 2.1 1.55 Smaller Fossil watches and chronographs
SR920SW (370/371) 9.5 2.1 1.55 Larger Fossil watches and some chronographs

Always verify the battery number on your existing battery before purchasing a replacement. Using the wrong battery can result in improper fit or damage to the watch movement.

Installing the New Battery

With the correct replacement battery at hand, the installation process involves:

  • Ensuring the battery compartment is clean and free of dust or debris.
  • Using plastic tweezers to place the new battery in the same orientation as the old one.
  • Securing the battery under the clip or strap, being careful not to bend or damage any components.
  • Checking that the battery sits flush and stable within its compartment.

After placing the battery, confirm the watch starts ticking or the digital display activates. If it does not, recheck the battery orientation and contact points for proper contact.

Reassembling the Watch

Once the new battery is installed and operational, the final step is to reattach the case back securely:

  • For snap-off backs, align the case back precisely with the watch body and press firmly until it snaps into place. Using a case press tool can help ensure an even and secure fit.
  • For screw-down backs, align the threads and rotate clockwise with the case back wrench until tightly secured, taking care not to over-tighten and strip the threads.

Be sure to verify that the watch is sealed properly to maintain water resistance. If your watch has a gasket or seal, inspect it for any damage and replace if necessary to preserve the watch’s integrity.

I’m Arron and I’ve always liked pulling things apart just to understand how they work. Watches were a natural obsession. Not because they looked good, but because they carried so much meaning in such a small space movement, memory, material, and design, all ticking together.

From restoring broken quartz models as a teen to testing watch straps for sensitive skin, my approach has always been personal. Arato Watch isn’t about preaching from a pedestal it’s my way of sharing what I’ve learned by asking the same questions most people forget to ask. I believe watches should be understood, not just worn. That’s exactly what this site is here to help you do.
