Step 2

Remove the four 3.7 mm-long Torx T2 screws.

Step 3

Insert the edge of a spudger into the middle loudspeaker opening at the top edge of your watch.

Step 4

The plastic clamps holding the back cover in place sit very tight and may require some force during the prying procedure.

Don't try to remove the back cover assembly all the way yet, it's still connected to the motherboard.

Carefully swing the back cover assembly open to an upward position.

Fine, the step 15 is quite difficult, because there is a pin into the U near the edge ... I did have to remove by the middle of the shield and pry It

Good job

Many thanks, worked perfect for me. When prying open the watch, I put it face up on the table and placed the side with the speaker on 5 mm thick solid elevation. I then pressed down with a spudger using the middle speaker opening as insertion point.

Re-assembled - no issues. But the capacitive touch screen does not work now - what do I need to check? Everything appears to be back in its place.
