What is the role of this part?

My watch’s glass was broken and I repaired(replaced) at personal fix store few months ago.

Today I found a gap between the glass and aluminium frame.

He was not a good engineer -_-;

I teared it and saw the flat cable(?) was cut ; the red line of the image.

Questions.

1. What is the role of the part that blue lined? Is there any disabled work by that disconnection?

2.Can I replace it? I couldn’t find that part by googling.

Answered! View the answer I have this problem too

Is this a good question?

The part is a foil shield to protect the display/touch assembly from EMI noise from the battery/SIP module blow it. Here’s a better view

The cut off segments (right side) are the connection point to the case (drain). Apple does not offer replacement parts.

As this point I don’t know if your watch is repairable or not. I hope you got your money back from this person as he clearly didn’t know what they where doing!

Shields are important! Maybe you can find a junker watch which you can salvage the shield from.
