Opening the Case Back of Your Tissot Watch

Before attempting to replace the battery, it is crucial to open the case back carefully to avoid damaging your Tissot watch. Depending on the model, Tissot watches typically feature either a snap-on case back or a screw-down case back.

For a snap-on case back, use a thin, flat tool such as a case knife or a precision flathead screwdriver to gently pry open the back. Locate the small notch or indentation on the edge of the case back, insert the tool carefully, and apply slight upward pressure to pop it open.

For a screw-down case back, you will need a case back wrench or a specialized Jaxa tool. Align the tool’s pins with the notches on the case back, then turn counterclockwise to unscrew it. Ensure you have a firm grip and work slowly to avoid slipping, which could scratch or damage the watch.

It is advisable to work on a clean, flat surface with a soft cloth to prevent scratches and to keep any small screws or parts from getting lost.

Removing the Old Battery

Once the case back is removed, you will see the battery secured under a small retaining clip or metal cover. The exact configuration varies by model, but the general steps are consistent:

  • Identify the battery compartment and note the battery type for replacement.
  • Use plastic tweezers or a non-metallic tool to avoid short-circuiting or damaging the components.
  • Gently lift or unscrew the retaining clip if necessary.
  • Carefully remove the battery from its compartment.

Take care not to touch other internal parts or the circuit board. If you encounter resistance, double-check for any screws or clips holding the battery in place.

Choosing the Correct Replacement Battery

Tissot watches use specific battery types that vary by model. Using an incorrect battery can affect the watch’s performance or cause damage. It is essential to match the battery code exactly.

The following table lists common battery types used in Tissot quartz watches along with their specifications:

Battery Code Voltage Diameter (mm) Height (mm) Common Equivalent
SR920SW 1.55V 9.5 2.1 371/370
SR626SW 1.55V 6.8 2.6 377
SR516SW 1.55V 5.8 1.65 357
SR621SW 1.55V 6.8 2.15 364

If unsure about the battery type, consult the watch manual or the engraved code on the battery itself.

Installing the New Battery

After obtaining the correct replacement battery, carefully place it into the battery compartment, ensuring the polarity matches the original orientation. Most watch batteries have a “+” side facing up, but verify before installation.

Re-secure any retaining clips or screws that hold the battery in place without applying excessive force. Avoid touching the battery surface with bare hands, as oils and dirt can reduce battery life or cause corrosion.

Before closing the case back, gently press the crown to check if the watch starts ticking, indicating the battery installation was successful.

Sealing the Case Back Properly

The final step is to reseal the watch to maintain water resistance and protect internal components. The method depends on the case back type:

  • For snap-on backs, align the case back with the watch case, then press down firmly and evenly until it snaps into place. Using a watch press tool is recommended for an even seal.
  • For screw-down backs, align the threads and turn clockwise using the case back wrench until snug. Do not overtighten as this may damage the threads.

Check the watch’s gasket or rubber seal for damage before closing. If the gasket is worn or cracked, replace it to maintain water resistance.

Testing and Final Checks

After battery replacement and resealing, it is important to verify the watch’s functionality:

  • Confirm the second hand is moving smoothly.
  • Set the time and date to ensure the crown and internal mechanisms operate correctly.
  • Check for any moisture inside the crystal or abnormal sounds.
  • If the watch is water-resistant, consider having it pressure tested by a professional to confirm the seal integrity.

If you encounter any issues or feel uncomfortable performing any step, it is advisable to consult a professional watchmaker or authorized Tissot service center.
