However, with the right approach and tools, it’s a manageable task that many watch owners can confidently tackle at home. Understanding the basics of your Fossil watch’s design and battery type is key to ensuring a smooth replacement process without damaging the watch.

In the following sections, you’ll discover essential tips and general guidance that will prepare you to replace your Fossil watch battery safely and efficiently. Whether you’re a seasoned DIY enthusiast or a first-timer, this overview will empower you to keep your watch running perfectly for years to come.

Removing the Back Cover of Your Fossil Watch

To replace the battery in a Fossil watch, accessing the internal components requires carefully removing the back cover. Fossil watches generally feature either a snap-off or screw-down case back, and identifying the type is essential before proceeding.

Snap-off case backs can usually be pried open with a small, thin tool such as a case knife or a flat-head screwdriver. Look for a small indentation or lip along the edge of the watch’s back where you can insert the tool. Apply gentle but steady pressure to pop the cover off without damaging the case or the gasket.

Screw-down case backs have multiple small notches around the edge and require a specialized case back opener tool with adjustable pins or a Jaxa wrench. Align the pins with the notches and turn counterclockwise to unscrew the back cover. Avoid using excessive force to prevent stripping the notches.

When removing the back cover, take the following precautions:

  • Work on a clean, flat surface with good lighting.
  • Use non-magnetic tools to avoid interference with the watch’s movement.
  • Place a soft cloth underneath the watch to prevent scratches.
  • Keep track of any small screws or components you remove.

Identifying and Replacing the Battery

Once the back cover is removed, you will see the watch’s battery secured in place, often held by a small clip or screw. Identifying the correct battery type is critical to ensure proper watch function after replacement.

The battery will have a series of letters and numbers printed on it, such as “SR626SW” or “CR2016.” Refer to your watch’s manual or Fossil’s official website for the exact battery model recommended for your watch.

To remove and replace the battery:

  • Use plastic tweezers or a non-metallic tool to carefully lift the battery out of its compartment.
  • Avoid touching the new battery with your bare hands; oils from skin can reduce battery life.
  • Insert the new battery with the correct polarity; the positive side usually faces up.
  • Ensure the battery is seated firmly and the clip or screw is reattached securely.
Common Fossil Watch Battery Types Battery Size (mm) Voltage (V) Typical Lifespan
SR626SW 6.8 x 2.6 1.55 1 to 2 years
CR2016 20 x 1.6 3.0 2 to 3 years
SR621SW 6.8 x 2.1 1.55 1 to 2 years
CR2025 20 x 2.5 3.0 2 to 3 years

Reassembling Your Fossil Watch

After the new battery is installed, reassembling the watch requires careful attention to ensure water resistance and proper function.

For snap-off backs, align the cover with the watch case and press firmly around the edges until you hear a click indicating it has snapped into place. Avoid forcing it unevenly to prevent bending the case or damaging the gasket.

For screw-down backs, position the cover carefully and use the case back opener tool to tighten by turning clockwise. Do not overtighten, as this could strip the threads or damage the gasket, compromising the watch’s water resistance.

Additional tips for reassembly:

  • Inspect the rubber gasket or O-ring for cracks or damage; replace it if necessary to maintain water resistance.
  • Clean any dust or debris from the gasket and watch case before closing.
  • Test the watch’s functions, including timekeeping and date setting, before wearing.

Once your Fossil watch is reassembled, it’s important to verify that the battery replacement was successful and maintain the watch for longevity.

  • Check that the watch hands are moving smoothly without stuttering or stopping.
  • Set the correct time and date according to your preference.
  • Observe the watch for at least 24 hours to confirm continuous operation.
  • If the watch has additional features such as chronograph or alarms, test these functions as well.

To prolong battery life and watch health:

  • Avoid exposing the watch to extreme temperatures or magnetic fields.
  • Have the watch pressure tested if it is water-resistant to ensure seals are intact.
  • Replace the battery immediately if the watch stops or shows signs of low battery to prevent leakage.

Following these expert steps will help ensure your Fossil watch continues to function accurately and reliably after a battery replacement.
