The retaining ring of the crystal was out by a fraction of a mm. When I pushed it back ( with force) it touched the dial an misformed it a bit. The dial is now not straight anymore but curved, althought only a bit. The curvation pushed the second hand off and got the day wheel stuck.
I will send it to Andy to do his miracles. Just in case it is not possible to use the dial anymore, where can I buy a new one?
Thanks for looking.
