How to fit a waterproof Apple Watch case without fog

The seal ring only works when the case is fully seated. Two minutes of care at installation decides whether the screen ever fogs.

Clean first

Wipe the screen with the wet wipe from the box, then dry it with the microfiber cloth. Any dust left on the display shows through the glass and can lift the seal.

Seat the case

Align the crown cutout, press the top edge in, then the bottom, until the case clicks all the way round. Run a fingernail along the edge — there should be no gap.

If moisture gets in

Take the case off, dry both parts and refit it. Fog usually means the case was not fully clicked in, or the watch went swimming — these cases are for daily water, not for the pool. After a screen repair, a sealed case also keeps dust out of the new glass while the adhesive settles.
