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.
