A little preparation goes a long way in preventing mistakes.

Step 3: Remove the Watch Band (Optional but Recommended)

While not always necessary, removing the watch band gives you better access to the sides and reduces the risk of damaging the straps during disassembly.

How to Remove the Band

• Locate the quick-release pins on the underside of the band connectors.
• Use a small pin tool or paperclip to press the pin and slide the band out.
• Set the band aside in a safe place.

Most T800 Ultra models use standard 22mm bands, so reattachment is straightforward.

Step 4: Locate and Remove the Back Cover Screws

The T800 Ultra typically has two to four tiny screws on the back cover, often hidden under rubber seals or stickers.

Finding the Screws

• Inspect the edges of the back cover carefully.
• Look for small circular indentations or rubber plugs.
• Gently peel back any rubber seals using a spudger—don’t force them.

Removing the Screws

• Use a Phillips #00 screwdriver to unscrew each one.
• Turn counterclockwise slowly and steadily.
• Place screws in your labeled container immediately.

Tip: If a screw feels stuck, don’t force it. Apply a tiny drop of isopropyl alcohol to loosen any adhesive, then try again.

Step 5: Separate the Back Cover from the Main Body

Once the screws are out, the back cover should lift off—but it may be held by clips or adhesive.

Using the Spudger

• Insert the plastic spudger into the seam between the back cover and the main body.
• Gently work your way around the edge, releasing clips.
• Apply even pressure—don’t pry too hard in one spot.

If the Cover Is Stuck

• Use a hairdryer on low heat (60–70°C) to soften adhesive for 30–60 seconds.
• Never use open flames or excessive heat.
• Reapply the spudger and gently lift.

Warning: Forcing the cover can crack the casing or damage internal components. Patience is key.

Step 6: Disconnect the Battery

Before touching anything else, disconnect the battery. This prevents accidental power surges.

Locating the Battery Connector
