If I replace my Apple Watch series 3 screen and put a new adhesive sell around the screen will it be water proof again
There are too many variables here! The skills of the person who works on your watchThe possible damage around the edge of the case so the display assembly does not sit fully downSurfaces are fully clean, heat and pressure are applied to make sure the adhesion of the parts are good Replacing the touch sensor as well as the display and the parts where hermetically sealed so the adhesive surfaces doesn’t degrade on the shelf. I wouldn’t go swimming but washing hands and quick showers should be fine. Even Apple won’t guarantee a repaired watch is waterproof again.
