Cannot remove screen from Apple Watch, quite stuck on!

I am trying to remove the screen of my Apple Watch series 2 and have put so much time and effort into trying to remove the screen and it simply will not lift off. I used the iOpener to warm it (up to 10 minutes!), an Xacto knife to get under the screen, a razor blade to get under there—I cannot get that screen lifted. Anyone else have this issue and what did you do?
