Any 6538 Big Crown experts? Crystal swap

[MySharona]

I'm trying to replace the super dome on my big crown with a lower profile t21.
Any pros to weigh in on exactly where the retaining ring might pop off? Having some trouble with this one.
Thank you!

Hi
Probably it's glued .
Remove the movement,
Heats witha an hairdryer
and push out the plexy.

Thanks!

... or is the crystal mounted directly on the case?
