This process involves more than just swapping out a power source; it requires attention to detail and the right tools to avoid damaging delicate components.

In the following sections, you’ll discover an overview of the essential steps and tips for safely replacing your Tissot watch battery. Whether you own a classic model or a modern design, gaining this knowledge empowers you to keep your watch running smoothly and confidently.

Tools Required for Battery Replacement

Replacing the battery of a Tissot watch requires precision and the right tools to avoid damage to the watch’s delicate components. Before starting the process, ensure you have the following items ready:

  • Case back opener or a small flat-head screwdriver (depending on the case back type)
  • Tweezers (preferably non-metallic to prevent short circuits)
  • Plastic prying tool or case knife
  • Soft cloth or watch holder to protect the watch face
  • Replacement battery (correct model for your Tissot watch)
  • Small brush or blower for cleaning dust particles
  • Magnifying glass or loupe for better visibility

Using the correct tools minimizes the risk of scratching the watch casing or damaging internal parts during the battery replacement procedure.

Identifying the Battery Type for Your Tissot Watch

Tissot watches use specific battery models depending on the movement and design. Identifying the correct battery type is crucial to maintaining optimal performance and avoiding potential damage caused by incorrect battery use.

You can identify the battery type by:

  • Checking the existing battery inside the watch, which typically has the model number inscribed.
  • Referring to the watch’s user manual or official Tissot documentation.
  • Consulting a professional watchmaker or authorized Tissot service center.

Below is a table of common Tissot watch battery types and their specifications:

Battery Model Voltage (V) Diameter (mm) Height (mm) Common Tissot Models
SR920SW (371) 1.55 9.5 2.1 PRC 200, T-Touch
SR626SW (377) 1.55 6.8 2.6 Classic, Couturier
CR2032 3.0 20.0 3.2 Some T-Touch Solar models

Ensuring you have the exact replacement battery model is essential for maintaining water resistance and the longevity of the watch.

Removing the Case Back

The procedure for removing the case back varies depending on whether the Tissot watch has a snap-off, screw-down, or screwed-in case back.

  • Snap-off Case Back: Use a case knife or a thin flat-head screwdriver to carefully pry open the back at the designated notch. Apply gentle pressure to avoid bending or scratching the case.
  • Screw-down Case Back: Employ a case back opener tool designed to fit the grooves or notches on the perimeter. Rotate counterclockwise to unscrew the back.
  • Screwed-in Case Back: Remove the small screws evenly with a precision screwdriver, placing them safely to prevent loss.

Always place the watch face down on a soft cloth to prevent scratches, and work in a clean, dust-free environment. Avoid excessive force, as this can cause irreversible damage.

Removing and Replacing the Battery

Once the case back is removed, the battery compartment will be visible. Proceed with caution:

  • Identify the battery retaining clip or spring mechanism holding the battery in place.
  • Use plastic tweezers to gently lift the clip or slide the battery out; metal tweezers may cause short circuits.

  • Before inserting the new battery, use a soft brush or blower to clean any dust or debris.
  • Place the new battery in the same orientation (usually positive side facing up).
  • Secure the battery with the clip or spring, ensuring it is firmly in place without forcing.

Improper battery placement can lead to malfunction or damage to the movement.

Testing and Reassembling the Watch

After installing the new battery, check the watch for proper operation:

  • Observe the second hand for movement or check any digital displays.
  • Adjust the crown to set the correct time if necessary.
  • If the watch fails to start, verify battery orientation and contact points.

When reassembling:

  • Clean the case back and gasket to remove dust or debris.
  • Inspect the gasket for wear or damage; replace it if necessary to maintain water resistance.
  • Carefully press or screw the case back into place, ensuring a secure fit.
  • For screw-down backs, tighten evenly and avoid over-torquing.

Maintaining the integrity of the gasket and case back is essential for water resistance and overall durability.

Handling your Tissot watch with care during battery replacement ensures longevity and reliability:

  • Always use the recommended battery type to avoid leakage or damage.
  • Avoid using excessive force when opening or closing the case back.
  • Consider having the gasket replaced or lubricated by a professional to maintain water resistance.

Regular battery replacement intervals, typically every 2-3 years, prevent battery leakage and maintain optimal watch performance.

Identifying the Correct Battery Type for Your Tissot Watch

Before beginning the battery replacement process, it is essential to identify the correct battery type compatible with your specific Tissot watch model. Using the wrong battery can damage the watch or cause improper functionality.

To identify the battery type:

  • Check the back case of your Tissot watch for engraved information, which sometimes includes the battery reference number.
  • Consult the user manual or official Tissot documentation related to your watch model.
  • If the above options are unavailable, carefully open the case back to read the battery label directly.
  • Alternatively, visit an authorized Tissot dealer or professional watchmaker for assistance.
