Before you begin, it’s important to gather the right tools and prepare your workspace. Using improper tools or rushing the process can lead to scratches, broken components, or even permanent damage to your watch. Here’s a list of everything you’ll need:

Precision screwdriver set: Look for a set that includes Phillips #00 and #0 sizes, as these are commonly used in small electronics.
Plastic pry tools or spudgers: These help separate the back cover without scratching the metal or glass.
Tweezers: Fine-tipped tweezers are useful for handling tiny screws and connectors.
Magnetic mat or small containers: To keep screws organized and prevent them from getting lost.
Anti-static wrist strap (optional but recommended): This helps prevent static electricity from damaging sensitive electronics.
Clean, well-lit workspace: A flat surface with good lighting reduces errors and eye strain.
Soft cloth or microfiber towel: Place this under the watch to protect it from scratches.

Optional but Helpful Tools

Heat gun or hairdryer: Some M26 models use adhesive to seal the back. Gentle heat can soften the glue, making removal easier.
Isopropyl alcohol (90% or higher): Useful for dissolving stubborn adhesive residue.
Magnifying glass or head loupe: Helps you see tiny screws and connectors clearly.

Safety First: Precautions to Take

Power off the watch: Go to Settings > Power Off before starting. This prevents accidental short circuits.
Remove the watch band: If your M26 has a removable band, take it off to give yourself more room to work.
Work in a static-free environment: Avoid carpeted areas and synthetic clothing that can generate static.
Handle the battery carefully: Lithium-ion batteries can be dangerous if punctured or exposed to heat.

Step 1: Power Down and Prepare Your Workspace

The first step in how to remove the back on a M26 smart watch is ensuring the device is completely powered off. This isn’t just a suggestion—it’s a critical safety measure. Even when the screen is off, the watch may still have residual power flowing through its circuits. Turning it off fully reduces the risk of shorting components when you touch internal parts.

To power off your M26:

Press and hold the side button until the power menu appears.
Tap “Power Off” and confirm.
Wait until the screen goes completely black and remains unresponsive to touch.

Once powered down, prepare your workspace. Choose a flat, clean surface like a wooden table or desk. Avoid working on beds, couches, or other soft surfaces where small parts can disappear. Lay down a soft cloth or microfiber towel to protect the watch’s exterior from scratches.

Good lighting is essential. Use a desk lamp or natural light to illuminate your work area. If possible, position the light so it shines directly on the watch without creating glare.

Finally, organize your tools within easy reach. Place your screwdrivers, tweezers, and containers in a row so you don’t have to search for them mid-process. This small step can save you time and frustration.

Step 2: Identify the Type of Back Cover on Your M26

Not all M26 smart watches are built the same. Some models have a screw-secured back, while others use adhesive or a snap-fit design. Before you start prying or unscrewing, it’s crucial to identify which type your watch has.

How to Tell the Difference

Screw-secured back: Look for tiny screws around the edge of the back cover. These are usually Phillips-head and may be hidden under rubber plugs or stickers.
Adhesive-sealed back: The back cover sits flush with the case and has no visible screws. It may feel slightly recessed or have a seamless look.
Snap-fit back: The cover clicks into place and can be removed with gentle prying. These are less common but still found in some budget models.

To determine your model:

Check the user manual or product listing online.
Look for model numbers printed on the back or inside the settings menu.
Search online forums or manufacturer support pages for your specific M26 variant.

If you’re unsure, start by looking for screws. Use a magnifying glass if needed. If you don’t see any, your watch likely uses adhesive. In that case, you’ll need to apply gentle heat to soften the glue before removal.

Step 3: Remove Screws (If Applicable)

If your M26 has a screw-secured back, this is the next step. Most models use 4 to 6 tiny Phillips-head screws located around the perimeter of the back cover. These screws are often very small—sometimes less than 2mm in diameter—so precision is key.

Step-by-Step Screw Removal

Locate all screws: Inspect the edge of the back cover carefully. Some screws may be hidden under rubber gaskets or stickers. Use a flashlight to spot them.
Use the correct screwdriver: A Phillips #00 or #0 is usually the right size. Using a larger driver can strip the screw head.
Turn counterclockwise: Apply gentle, steady pressure while turning. Don’t force it—if a screw feels stuck, it may be locked with thread locker.
Store screws safely: Place each screw in a labeled container or on a magnetic mat. Note their positions if they vary in size.

Tips for Stubborn Screws

If a screw won’t budge, apply a tiny drop of isopropyl alcohol to loosen any adhesive.
Use a rubber band between the screwdriver and screw head for extra grip.
Never use pliers or excessive force—this can damage the casing or strip the screw.

Once all screws are removed, set them aside. The back cover should now be loose, but it may still be held in place by adhesive or internal clips.

Step 4: Apply Heat to Loosen Adhesive (If Needed)

Many M26 smart watches use strong adhesive to seal the back cover for water resistance. If your model doesn’t have screws, or if the screws are removed but the back won’t lift, heat is likely needed.

How to Apply Heat Safely

Use a heat gun or hairdryer: Set it to low or medium heat (around 150°F to 180°F).
Keep it moving: Hold the tool 6–8 inches away and move it in slow circles around the edge of the watch.
Heat for 1–2 minutes: Focus on the perimeter where the back meets the case.
Test with a plastic tool: After heating, gently insert a plastic pry tool into the seam. If it slides in easily, the adhesive is softened.

Precautions When Using Heat

Don’t overheat the watch—excessive heat can damage the battery or screen.
Avoid direct heat on the screen or sensors.
Wear heat-resistant gloves if using a heat gun.
If the watch feels too hot to touch, let it cool before proceeding.

Step 5: Gently Pry Open the Back Cover

With screws removed and adhesive softened, it’s time to separate the back cover from the main body. This step requires patience and the right tools.

Using Plastic Pry Tools

Insert the tool: Slide a plastic spudger or guitar pick into the seam between the back and the case.
Work slowly around the edge: Gently wiggle the tool to break the seal. Don’t force it—apply even pressure.
Create a gap: Once you’ve loosened one section, move to the next. Continue around the perimeter.
Lift carefully: When the seal is broken, lift the back cover at a slight angle. Avoid pulling straight up, as this can damage internal connectors.

What to Do If It Won’t Budge

Reapply heat for another 30–60 seconds.
Check for hidden screws you may have missed.
Use a second pry tool to gently lift from the opposite side.
Never use metal tools like knives or screwdrivers—they can scratch or crack the casing.

Step 6: Disconnect Internal Components (If Necessary)

Once the back is off, you may see internal components like the battery, charging coil, or sensor array. In most cases, these are connected via small ribbon cables or snap connectors.

How to Safely Disconnect Cables

Identify the connectors: Look for flat ribbon cables with small plastic tabs.
Use tweezers or a spudger: Gently lift the tab to release the cable. Don’t pull on the cable itself.
Take photos: Snap pictures of the connections before disconnecting. This helps during reassembly.
Label if needed: Use tape and a marker to label cables if there are multiple.

Handling the Battery

If you’re replacing the battery:

Disconnect it first to avoid short circuits.
Avoid bending or puncturing the battery.
Do not expose it to heat, water, or metal objects.
If the battery is swollen, stop immediately and consult a professional.

Step 7: Inspect and Perform Repairs

With the back removed, you can now inspect the internal components. Common issues include:

Dried or cracked adhesive
Corroded battery contacts
Loosen ribbon cables
Dust or moisture inside the casing

Cleaning and Maintenance Tips

Use a soft brush or compressed air to remove dust.
Clean contacts with a cotton swab and isopropyl alcohol.
Check for signs of water damage (white residue, corrosion).
If replacing the battery, ensure the new one is compatible with your M26 model.

Step 8: Reassemble the Watch

Reassembly is the reverse of disassembly—but it’s just as important.

Step-by-Step Reassembly

Reconnect all cables: Ensure each ribbon cable is fully seated and locked in place.
Position the back cover: Align it carefully with the case.
Press down gently: Use even pressure to snap or seal the cover.
Reinsert screws: Tighten them in a cross pattern to ensure even pressure.
Apply new adhesive (if needed): Use a small amount of waterproof adhesive around the edge.

Final Checks

Power on the watch and test all functions.
Check for water resistance if you resealed it.
Ensure the screen responds to touch and buttons work.

Troubleshooting Common Issues

Even with careful handling, problems can arise. Here’s how to fix the most common ones:

Back Cover Won’t Stay On

Cause: Weak or missing adhesive.
Solution: Apply a thin layer of waterproof adhesive and let it cure for 24 hours.

Watch Won’t Turn On After Reassembly

Cause: Loose or disconnected battery cable.
Solution: Open the back and recheck all connections.

Screen Glitches or Touch Issues

Cause: Damaged ribbon cable or static discharge.
Solution: Reconnect cables carefully. If problems persist, the screen may be damaged.

Screws Won’t Tighten

Cause: Stripped screw holes.
Solution: Use a slightly larger screw or apply a drop of super glue to the thread.
