Tools and Materials Needed for Battery Replacement

Before beginning the battery replacement process on your Tissot watch, it is essential to gather the correct tools and materials to ensure a smooth and safe operation. Using improper tools can damage the watch’s delicate components or compromise its water resistance.

Essential tools include:

  • Case Back Opener: A specialized tool to safely open the watch case back without scratching or damaging it. Tissot watches may have screw-down, snap-back, or screw-in case backs, so the opener should be compatible.
  • Plastic Tweezers: To handle the battery without causing short circuits or corrosion. Metal tweezers can damage the battery or the circuitry.
  • Small Flathead Screwdriver: Sometimes required to release battery clips or remove retaining screws.
  • Battery Tester (optional): To verify the new battery’s charge before installation.
  • Soft Cloth or Pad: To place the watch on and avoid scratches during the process.

Additionally, ensure you have the correct replacement battery, which varies depending on the specific Tissot model. Refer to the watch manual or the existing battery for the exact type.

Tool/Material Purpose Notes
Case Back Opener Open watch case back Choose based on case back type: screw-down or snap-back
Plastic Tweezers Handle battery safely Prevents short circuits and corrosion
Small Flathead Screwdriver Remove battery clips or screws Delicate use to avoid damage
Battery Tester Check battery charge Optional but recommended for quality assurance
Soft Cloth/Pad Protect watch surface Prevents scratches during handling

Step-by-Step Procedure to Replace the Battery

Begin by working in a clean, well-lit environment to avoid losing small components. Follow these steps carefully:

  • Remove the Case Back: Use the case back opener to carefully unscrew or pry open the back of the watch. For screw-down backs, turn the tool counterclockwise. For snap-backs, gently insert a case knife into the notch and lift.
  • Locate the Battery: Once the back is removed, identify the battery compartment. It is usually held in place by a clip or small screws.
  • Remove the Battery Clip or Screws: Using the small flathead screwdriver, carefully loosen any screws or release the clip securing the battery.
  • Extract the Old Battery: With plastic tweezers, lift the battery out gently, avoiding contact with the internal circuitry.
  • Check the Battery Voltage: Use a battery tester to confirm if the old battery is depleted.
  • Insert the New Battery: Using plastic tweezers, place the new battery in the exact orientation as the old one, usually with the positive side facing up.
  • Secure the Battery: Replace the clip or screws to hold the battery firmly in place.
  • Test the Watch: Before closing the case back, verify that the watch is running correctly.
  • Replace the Case Back: Position the case back and press or screw it back into place securely, ensuring any gaskets are properly seated to maintain water resistance.

During the process, avoid touching the battery terminals with your fingers, as oils and moisture can reduce battery life or cause corrosion.

Common Issues and Tips for a Successful Replacement

Battery replacement can sometimes present challenges, especially with luxury watches like Tissot, which require careful handling to preserve their value and functionality.

Some common issues include:

  • Difficulty Opening the Case Back: If the case back is stuck, avoid using excessive force. Instead, apply a small amount of penetrating oil around the edge or consider professional assistance.
  • Damaged Gasket: The rubber gasket seals the watch against water intrusion. If it appears cracked or brittle, replace it during the battery change to maintain water resistance.
  • Incorrect Battery Orientation: Installing the battery backward can prevent the watch from working or cause damage. Always match the polarity.
  • Static Electricity: To avoid damaging the watch’s electronic components, work on a grounded surface and avoid static discharge.
  • Water Resistance Testing: After replacement, if your watch is water-resistant, it is advisable to have it pressure tested by a professional to ensure the seal integrity.

Tips for success:

  • Take note or photograph the battery orientation before removal.
  • Use dedicated watchmaker tools to prevent slips and damage.
  • Handle internal components with care to avoid bending or breaking.
  • Consider professional servicing if unsure about any step or if the watch has additional complications.

Following these guidelines will help ensure your Tissot watch continues to function reliably after a battery replacement.

Identifying the Battery Type in Your Tissot Watch

Before beginning the battery replacement process, it is essential to correctly identify the type of battery your Tissot watch requires. Different models use various battery types, which affect compatibility and performance.

To determine the correct battery:

  • Consult the watch’s user manual or warranty card where the battery type is often specified.
  • Inspect the back case of the watch for any engraved model or battery reference numbers.
  • If uncertain, open the back case carefully (see next section) to view the battery directly and note its markings, usually printed on the battery itself.
  • Use reputable online resources or contact Tissot customer service with your watch’s model number for verification.

Common battery types used in Tissot watches include silver oxide batteries, such as SR920SW, SR626SW, or specialized lithium button cells depending on the movement.
