The warning to turn off the watch to avoid electrical shock was a joke, right?!

The screws don't seem to be turning easily. What's the best way to loosen them without stripping them?

I’m going to be shocked by a dead 3.8V battery? Of course, only if the watch is powered on. Ridiculous statements like this do not reflect positively on the credibility of this entire procedure. If the author seriously thinks this is a danger then I question your basic understanding of electronics.

Étape 2

Using your finger, push forward on the release while pulling up on the strap.
You may find it helpful to use the flat end of a spudger to push on the release instead of your finger.

Insert a plastic opening tool between the top and bottom portions of the case, and gently pry off the back.
Do not insert the tool more than 3 millimeters into the case. Inserting more than 3 mm may damage the seal and electric components.

My watch had sticky glue between the top and bottom portions of the case. I don’t think my watch will be as waterproof after this repair.
