Removing the back of a Tissot watch can be a delicate task, requiring precision, care, and the right tools. Whether you’re looking to change the battery, repair internal components, or simply explore the intricate mechanics of your timepiece, this guide will walk you through each step with clarity and detail.
Understanding Tissot Watch Backs
Before diving into the removal process, it’s essential to understand the different types of watch backs that Tissot uses. Generally, Tissot watches have one of the following types of backs:
Snap-Off Backs: These are pressure-fitted and can be pried open.
Screw-Down Backs: These require a specific tool to unscrew.
Case Backs with Screws: These have small screws holding the back plate in place.
Knowing your watch’s specific back type will determine the tools you need and the method you’ll use.
Tools You’ll Need
Case Knife or Pry Tool: For snap-off backs.
Case Wrench: For screw-down backs.
Precision Screwdrivers: For backs with screws.
Rubber Ball (Friction Ball): Sometimes used for screw-down backs.
Clean Cloth: To protect the watch and provide a clean working surface.
Magnifying Glass: To get a better view of small components.
Tweezers and Small Picks: For handling tiny parts inside the watch.
Anti-Static Wrist Strap: To prevent static damage to electronic components.
Preparation Steps
Find a Clean, Well-Lit Workspace: Ensure your work area is tidy and well-lit. A clean surface prevents small parts from getting lost.
Gather Tools: Have all your tools within easy reach.
Remove the Watch Band: This makes it easier to handle the watch. Use a spring bar tool to remove the band if necessary.
Wear Gloves: If you’re concerned about fingerprints or oils, wearing gloves is a good precaution.
Removing a Snap-Off Back
Step-by-Step Instructions
Locate the Pry Slot: Examine the edge of the watch back to find a small indentation or notch. This is where you’ll insert your tool.
Insert the Case Knife: Gently insert the case knife or pry tool into the notch.
Apply Gentle Pressure: Carefully twist the tool to pop the back off. Be patient and avoid excessive force, as this can damage the watch.
Lift the Back: Once it’s loosened, lift the back off with your fingers or tweezers.
Tips for Success
Work Slowly: Rushing can cause scratches or damage.
Use the Right Tool: A dedicated case knife is ideal, but a thin, flat blade can work in a pinch.
Be Gentle: Avoid prying too hard or you might bend the back or damage the gasket.
Removing a Screw-Down Back
Step-by-Step Instructions
Identify the Case Back Type: Screw-down backs typically have notches or grooves around the edge.
Fit the Case Wrench: Adjust the case wrench to match the notches on the watch back.
Turn Counterclockwise: Firmly hold the watch in place and turn the wrench counterclockwise to unscrew the back.
Use a Rubber Ball: If the back is very tight, a rubber ball can sometimes provide the needed grip to unscrew it.
Tips for Success
Proper Tool Fit: Ensure the wrench fits perfectly to avoid slipping.
Steady Hand: Keep the watch stable to prevent scratches.
Check Gasket: Inspect the gasket once the back is removed. Replace if damaged.
Removing a Case Back with Screws
Step-by-Step Instructions
Locate the Screws: Use a magnifying glass to find the tiny screws around the edge of the back.
Select the Right Screwdriver: Use a precision screwdriver that fits the screw heads perfectly.
Unscrew Carefully: Turn the screws counterclockwise to remove them. Keep the screws safe in a small container.
Lift the Back: Gently lift the back off once all screws are removed.
Tips for Success
Organization: Keep screws organized to avoid losing them.
Gentle Handling: Avoid stripping the screws by using the correct size screwdriver.
Clean Workspace: A tidy workspace helps prevent lost screws.
Common Challenges and Solutions
Stubborn Back Removal
If the back is not coming off easily, don’t force it. Apply a small amount of penetrating oil around the edge and let it sit for a few minutes. This can help loosen the back. Use a rubber ball or a piece of adhesive tape for extra grip.

Damaged Gasket
A damaged gasket can compromise the watch’s water resistance. Inspect the gasket for any signs of wear or damage. Replace it if necessary. Gaskets can be purchased from watch supply stores or directly from Tissot.
Handling Small Parts
The internal components of a watch are delicate and small. Use tweezers and small picks to handle these parts carefully. Keep a magnifying glass handy for better visibility.
Reassembling the Watch
Step-by-Step Instructions
Clean the Case Back: Before reassembly, clean the case back and the gasket with a soft cloth.
Inspect the Gasket: Ensure the gasket is in good condition and seated properly.
Align the Case Back: Place the back onto the watch case, aligning it correctly.
Secure the Back: Depending on the type, either snap it back on, screw it down, or replace the screws.
Tips for Success
Even Pressure: Apply even pressure when snapping or screwing the back on.
Check Alignment: Ensure everything is aligned correctly to avoid damage.
Test Water Resistance: If the watch is water-resistant, have it professionally tested after reassembly.
Safety and Maintenance Tips
Avoid Excessive Force: Never force the back off. Use the right tools and gentle pressure.
Regular Maintenance: Regularly check the watch’s gasket and replace it as needed to maintain water resistance.
Professional Help: For complicated repairs or high-value watches, consider professional servicing.
