Seeking advice on installing watch crystal.

[Ruehara]

Repaired an old Tissot stylist a while ago, but the only thing I was never happy about was the crystal, polished it however there were some scratches that were too deep to remove. Recently found a matching acrylic crystal from cousins that should fit the watch. The problem is i'm not actually sure how to install the crystal into the case. It doesn't appear to be glued in, and there is a small lip in the crystal and a groove in the case for it to fit into. I tried using a crystal lift and also a crystal press (with round dies) on the old crystal as i don't mind damaging it. 

Any advice would be appreciated, hoping i'm missing something simple. Thanks!

The only way I've ever know to do these is by hand.

that's how I've always done them. Start at one side and work your way around feeding the edge in with your fingernails. If you hit a spot that won't enter, check that the edge isn't getting damaged, if so remove and feed that bit in first. if it's really tight you may need to reduce the size very slightly.

Sounds like this might be the way then.
