Be aware that a sharp tool easily scratches your watch housing when not handled with care. To avoid undesired scratches, take your time and work carefully rather than hastily.

Place the edge of a curved blade into the thin gap between the display and the outer case. Start at the short side of the display, most distant to the digital crown.

Once inserted, tilt the blade to pry the display open slightly and create a gap between the screen and the watch body.

The Apple Watch Series 7 display is equipped with a plastic bezel on its rear side. If you want to reuse your display, avoid using too much pressure with the knife or you may separate the bezel from the screen.
