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

Tutoriel très bien détaillé, j'ai suivi toutes les étapes sans problème, merci pour cete aide précieuse.

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.
