Schritt 1 Battery  ¶ 

Place the heated iOpener on the face of the watch.

Schritt 1 Battery  ¶ 

  • Place the heated iOpener on the face of the watch.

  • Leave the iOpener on the watch for at least a minute to heat the screen and soften the adhesive holding it to the case.

  • You may need to reheat the iOpener, or move it around on the screen as sections cool, to heat the screen enough to pry it off.

Schritt 2  ¶ 

Because the gap between the screen and watch body is so thin, a sharp blade is required to separate the two. Read the following warnings carefully before proceeding.

  • Because the gap between the screen and watch body is so thin, a sharp blade is required to separate the two. Read the following warnings carefully before proceeding.

  • Always keep your fingers completely clear of the knife.

  • Be careful not to apply too much pressure, as this might cause the knife to slip and cut you, or damage the watch.

  • Wear eye protection. The knife or glass may break, sending pieces flying.

Schritt 3  ¶ 

Using a curved blade minimizes the chance of scratching the case or cracking the glass. Only pry with the curved section of the blade, and not the tip or flat section. Place the curved section of the blade in the gap between the glass and case on the lower edge of the watch face, and press firmly down into the gap. Be very careful to maintain complete control over the knife—once the gap opens, if you're pressing too hard on the knife it may slip in and cut the battery.

  • This should wedge the gap open and cause the glass to lift slightly up from the case.

  • When the glass has lifted, gently rotate the knife down, opening the gap more by pushing the glass up.

Schritt 4  ¶ 

Once you've opened the gap enough, insert the tip of an opening pick under the glass. Slide the pick along the bottom edge to separate adhesive holding the screen to the case. Be careful not to insert the opening pick too far. Only about 1/8" ( about 3 mm) is necessary, any deeper and you may damage cables.

Schritt 5  ¶ 

Roll the opening pick up the side of the button side of the watch, gently pushing in to separate the adhesive and widening the gap as you go. Remember not to push the pick in too far—it's easier to avoid this by rolling the pick, rather than dragging a tip along.

Schritt 9  ¶ 

There are two cables connecting the screen to the inside of the watch, near the top left corner. Be careful when prying or you may damage these cables. Pry slightly up on the right side of the screen, to free it from any remaining adhesive. Pry up on the left to free it as well—but do not attempt to remove the screen as it is still held in place by two cables.

Schritt 10  ¶ 

If you can see the top layer of your Force Touch sensor among the display adhesive, it means the two layers of the sensor separated and you're going to need to replace or repair it. The top layer of the sensor may be adhered to the back of the screen—push it down to separate it, and switch to our Force Touch Sensor guide from this point on.

Schritt 12  ¶ 

Place the watch on an elevated surface, at least 1/2" or 1 cm tall—a small box or the edge of a book will work great. This will allow the screen to hang down vertically and give better access to the battery.
