Not a comment but a question: What happens with the waterproofing of the watch with this?

Arthur Mize - Reply

Of course with a take apart of any device the waterproofing will be gone unfortunately.

Mister HD -

Id heavily consider rewriting step 4. I almost pried the board off with the screws still attached because I read from left to right on the pictures. Device is okay but I was assuming an entire unit attached with screws was coming out of a shell. Good guide otherwise, thanks
