I’ve done a few of these (on citizens)
My methods been to place the watch in a holder then in a vice, tape up the watch and face just exposing the Cyclopes- apply a small amount of acetone on a cocktail stick (carefully as obviously gaskets don’t like it) around the edge of the cyclops
And I think the last one I just tapped a glancing blow very gently with a small chisel and pin hammer - I’ve also done it with pin hammer and Stanley blade
Then just clean it up
Good luck - balls out
I’d remove the bezel 1st
Careful you won’t mark the crystal
