6 steps
  1. Lifting the display

    1. First you have to heat your Apple Watch’s display using a heat gun.
    2. The gap between the aluminum frame and the display is very small. We recommend that you use a very flat, sturdy object to get between them.If you’re using a sharp blade, make sure it doesn’t slip. If necessary, wear appropriate gloves.
    3. Carefully lift the display using a suction cup.
    4. As soon as a little gap opens up, use the plastic pick to avoid damaging the aluminum.
  2. Inserting the pick

    1. You should only insert the pick about two or three millimeters between the display and the frame to prevent damage inside the enclosure.
    2. The display is glued to the entire outer edge of the Apple Watch. Move the pick once around the entire device.
    3. The NFC antenna also acts as a seal and is glued to the aluminum enclosure. Make sure you don’t lift it with the display and that it stays on the aluminum frame.
  3. Lifting the display

    1. Once you’ve detached all the glue, you can carefully lift the display.
      There are two cables connected to the display at the upper left corner.
    2. Now you can pull the display off to one side so you can see the cables.
  4. Removing the battery

    Note: You don’t need to remove the display. We just removed it so you can get a better idea of the process.

    1. The little battery is only lightly glued in place. Carefully lift it with a spudger.
    2. Now disconnect the cable’s connector using the spudger.
    3. Then you can remove the battery.
  5. Inserting the battery

    1. Check all the functions of your Apple Watch before you attach the display again.
    2. Now check whether the seal’s glue is still sticky enough.
    3. If everything’s okay, you can put the display back on. Heat it slightly and press it into the enclosure for a few minutes.
    4. Now you can use your Apple Watch as usual. Have fun!
