First push the crown back in.
If you look at the pic
You should see a dimple where the arrow is pointing. The crown should be in the "IN" position. Press down at this point while pulling gently on the crown.
I replaced a crystal on one of these recently and found that it was quite difficult to get the back on.
Eventualy I resorted to the following.
Take out the nylon sealing ring and fit it onto the case back.
Put the caseback/sealing ring into a plastic bag and put it in the freezer compartment.
Allow to cool down and quickly refit to case. (I used a caseback press). If you damage the nylon sealing ring they are stocked by Cousins.
Hope this helps.
Kind regards
Dave
