  • Gloves or finger cots to avoid oils contaminating internal parts

Having these tools ready will help maintain the integrity of the watch while replacing the battery efficiently.

Step-by-Step Procedure to Change the Battery

Replacing the battery of a Tissot watch requires precision and care. Follow the steps below carefully:

  • Place the watch face down on a soft, clean cloth to avoid scratches.
  • Identify the type of case back: snap-on, screw-down, or held by screws.
  • Use the appropriate case back opener:
  • For snap-on backs, gently insert a case knife or blade under the lip and pry open.
  • For screw-down backs, use a case back wrench or adjustable tool to unscrew.
  • For screw-secured backs, use a precision screwdriver to remove screws.
  • Carefully lift the case back and set it aside.
  • Locate the battery holder; it may be secured by a clip or small screw.
  • Using plastic tweezers, carefully remove the old battery to avoid short circuits.
  • Check the battery compartment for corrosion or debris; clean gently if needed.
  • Insert the new battery in the correct orientation (observe polarity).
  • Replace the battery holder clip or screw if applicable.
  • Before sealing the case, check the watch for proper functioning.
  • Apply silicone grease to the case back gasket to ensure water resistance.
  • Carefully reattach the case back, ensuring it is properly aligned and sealed.

Battery Types Compatible with Tissot Watches

Tissot watches use various battery types depending on the model and movement. Using the correct battery is essential for optimal performance and longevity.

Below is a table of common battery types used in Tissot watches, along with their specifications:

Battery Model Type Voltage Typical Usage Equivalent Codes
SR920SW Silver oxide 1.55 V Common quartz watches 371, 920
SR927SW Silver oxide 1.55 V Chronograph models 395, 927
CR2016 Lithium 3 V Digital and multifunction watches DL2016
SR626SW Silver oxide 1.55 V Small dial watches 377, 626

Always verify the battery model by checking the existing battery or consulting the watch’s user manual.

Precautions and Tips for Maintaining Water Resistance

Maintaining the water resistance of a Tissot watch after battery replacement is critical, especially for dive or sport models. Improper sealing can lead to moisture ingress, causing corrosion and damage.

Key precautions include:

  • Inspect the rubber gasket or O-ring for any signs of wear, cracks, or deformation before resealing.
  • Replace the gasket if it appears compromised; genuine replacement parts are recommended.
  • Apply a thin layer of silicone grease on the gasket to improve sealing and longevity.
  • Ensure the case back is aligned correctly before applying pressure or screwing it back on.
  • Avoid overtightening screw-down case backs, which can damage threads or gaskets.
  • For watches with screw screws on the case back, tighten evenly to avoid uneven pressure.
  • After resealing, perform a water resistance test if possible, especially if the watch is intended for underwater use.

Taking these measures will help preserve the watch’s integrity and functionality after battery replacement.

Identifying the Battery Type for Your Tissot Watch

The first step in changing the battery on a Tissot watch is determining the specific battery model required. Tissot watches use different types of batteries depending on the model and movement. Using the correct battery ensures optimal performance and prevents damage.

  • Check the Watch Manual: The most reliable source for the battery type is the user manual that came with your watch.
  • Inspect the Existing Battery: If the watch has stopped working, open the case back (following proper procedures) and note the battery code printed on the battery.
  • Consult Tissot’s Official Resources: Visit Tissot’s website or authorized service centers for battery specifications tailored to your model.
Common Tissot Battery Codes Battery Type Voltage Typical Watch Models
SR920SW Silver Oxide 1.55 V Many quartz analog models
CR2032 Lithium Coin Cell 3 V Some digital and multifunction watches
SR626SW Silver Oxide 1.55 V Smaller analog quartz watches

Gathering Tools and Preparing Your Workspace

Before beginning the battery replacement, assemble the necessary tools and prepare a clean, well-lit workspace to avoid damage or loss of small parts.

  • Essential Tools:
    • Watch case opener (case knife or case back opener tool)
    • Plastic tweezers (to handle the battery and avoid short circuits)
    • Small screwdriver set (for movement clamps or screws if applicable)
    • Soft cloth or watch holder to protect the watch face and stabilize it
    • Magnifying glass for detailed inspection
  • Preparation Tips:
    • Remove any jewelry or loose clothing to prevent snags.
    • Work on a flat surface with adequate lighting.
    • Keep a small container nearby to hold screws or small components.
    • Ground yourself to discharge static electricity, which can damage electronic parts.

Opening the Case Back of a Tissot Watch

Tissot watches generally have two types of case backs: snap-off or screw-down. Properly opening the case back is critical to avoid damage to the watch.

  • Snap-Off Case Back:
    • Locate the small indentation or notch on the edge of the case back.
    • Insert a case knife or a thin blade carefully into the notch.
    • Apply gentle pressure to pry the case back open. Do this slowly to prevent bending or scratching.
  • Screw-Down Case Back:
    • Identify the small grooves or notches around the perimeter of the case back.
    • Use a case back wrench with adjustable pins fitting into these grooves.
    • Turn counterclockwise to unscrew the case back carefully.
    • Ensure the watch is secured in a holder to prevent slipping.

Important: If the watch has a sealed gasket for water resistance, take care not to damage or dislodge it. Consider replacing the gasket during reassembly to maintain water resistance.

Removing the Old Battery Safely

Once the case back is removed, the battery will be visible, often secured by a small clip or retainer.

  • Identify the battery holder type:
    • Spring clip
    • Screw-down retainer
    • Plastic or metal tab
  • Use the appropriate tool (plastic tweezers or small screwdriver) to carefully release the battery holder.
  • Gently lift the battery out without touching any other components.
  • Note the battery orientation (positive and negative sides) for correct installation of the new battery.
  • Avoid using metal tools directly on the battery to prevent short circuits or damage.

Installing the New Battery and Reassembling the Watch

Proper installation of the new battery ensures the watch functions correctly and maintains its water resistance.

  • Place the new battery in the compartment, matching the orientation of the old battery exactly.
  • Secure the battery with the clip or retainer without forcing it.
  • Check that the movement is running before closing the case back.
  • If the watch has a gasket, inspect it carefully:
    • If damaged or dried out, replace it with

      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.
