AvatarByArmando Lewellen Watch Brands

Replacing the battery in your Tissot watch is a practical skill that can save you time and money while keeping your cherished timepiece ticking accurately. Whether your watch has stopped working or is running slow, a fresh battery can often restore its performance and extend its lifespan. Understanding the basics of how to replace a Tissot watch battery empowers you to maintain your watch with confidence and care.

Tissot watches are known for their precision and craftsmanship, and like any quality timepiece, they require periodic maintenance to function at their best. Battery replacement is one of the most common services needed, but it’s important to approach the process with the right tools and knowledge to avoid damaging the watch’s delicate components. Learning the essentials before diving into the task ensures a smooth and successful battery change.

In the following sections, you’ll discover what makes Tissot watches unique, the signs that indicate a battery replacement is due, and the general steps involved in safely changing the battery. Whether you’re a seasoned watch enthusiast or a first-time DIYer, this guide will prepare you to handle your Tissot watch battery replacement with ease and precision.

Opening the Watch Case

To replace the battery in a Tissot watch, the first step is to carefully open the watch case. The method varies depending on the model and type of case back. Tissot watches typically have one of the following case back types:

  • Snap-back case: This type of case snaps onto the watch and requires a case knife or a thin blade to pry it open.
  • Screw-down case: This type has notches around the perimeter and requires a specialized case wrench or a Jaxa tool to unscrew it.
  • Screw-in case with screws: Small screws secure the back, and a precision screwdriver set is necessary.

Before attempting to open the case, ensure you work on a clean, flat surface with good lighting. Use a soft cloth or pad to protect the watch face from scratches.

Steps for opening:

  • Examine the case back to identify the type.
  • If it’s a snap-back, locate the small indentation or lip designed for prying.
  • Insert the case knife carefully and gently twist to pop the back off.
  • For screw-down backs, align the case wrench with the notches and turn counterclockwise.
  • For screw-in backs, use the appropriate screwdriver to remove all screws evenly.

Be cautious to avoid slipping and damaging the case or internal components.

Removing the Old Battery

Once the case is opened, the next task is to remove the old battery safely. Tissot watches usually house a small button cell battery, secured either by a metal clip or a plastic cover.

Key points to consider:

  • Avoid touching other components inside the watch to prevent damage or displacement.
  • Note the orientation and position of the battery before removal.
  • Use non-metallic tweezers or plastic tools to avoid short circuits.

Procedure:

  • Identify the battery compartment and any securing clips.
  • If present, gently lift or unscrew the clip holding the battery.
  • Carefully extract the battery using tweezers.
  • Inspect the battery compartment for corrosion or dirt and clean if necessary with a soft brush or cloth.

Choosing the Correct Replacement Battery

Selecting the right battery is crucial for optimal watch function and longevity. Tissot watches commonly use silver oxide button cells, but the specific battery type varies by model.

The battery type is often engraved on the battery itself or documented in the user manual. Common battery designations include:

Battery Model Typical Voltage Common Tissot Models Remarks
SR626SW (377) 1.55V Many quartz Tissot watches Standard silver oxide battery
SR920SW (370) 1.55V Some chronograph models High capacity
CR2016 3V Digital or multifunction models Lithium battery

If uncertain, consult the Tissot manual or a professional watchmaker to confirm the correct battery type. Using an incorrect battery can cause malfunction or damage.

Installing the New Battery

Installing the new battery requires precision and care to maintain the watch’s integrity and water resistance.

Guidelines for installation:

  • Ensure the new battery matches the original in size and voltage.
  • Handle the battery with clean hands or plastic tweezers to avoid contamination.
  • Insert the battery in the exact orientation as the original, paying attention to polarity (+/-).
  • Secure the battery with the clip or cover.
  • Before closing the case, test the watch to confirm proper operation.

If the watch does not start immediately, remove and reinsert the battery, or verify the battery’s charge.

Closing the Watch Case

After confirming the watch is running with the new battery, the case must be closed securely to maintain water resistance and protect internal components.

Steps for closing:

  • Inspect the gasket or rubber seal on the case back for damage or dirt. Replace or clean if necessary to ensure a proper seal.
  • Align the case back correctly with the watch body.
  • For snap-back cases, press firmly using a case press or by hand until it snaps into place.
  • For screw-down cases, use the case wrench to tighten the back evenly but avoid over-tightening.
  • For screw-in backs, reinsert all screws evenly and tighten gently.

After closing, check the watch’s functionality and set the time as needed.

Additional Tips and Precautions

  • Work in a dust-free environment to prevent debris from entering the watch.
  • Avoid using excessive force to open or close the case.
  • If you encounter resistance or difficulty at any step, consider consulting a professional.
  • Dispose of old batteries responsibly at designated recycling points.
  • Regularly replace the battery every 2-3 years to maintain optimal performance.

By following these detailed steps and precautions, you can confidently replace the battery in your Tissot watch while preserving its quality and performance.
