Longiness La Grande Classique movement removal

[Daimon]

Hi!

Struggling with movement removal in Longiness La Grande Classique. Photo tells everything:

To remove movement I need to remove hands and dial only comes out front side - i.e. need to remove crystal without removal of movement.

Removed crown, and tried with syringe and o-ring but no luck - getting pressure leaks from place when syringe contacts with o-ring/watch before crystal pops (even though I feel significant pressure on syringe). Any ideas?

I can not tell from picture if the crystal sits in a removable bezel which would solve the issue .....other wise you will need more pressure to pop crystal out

[Daimon]

Nope, there's no bezel there. 3d printed tight fitting adapter and tried with 60ml syringe literally using my full arm - no luck.

Just watched a  video, the method you are using is the recommended one. So why it isn't working, I  don't know.  Could someone of glued the crystal in?

Ok managed to apply enough  pressure:

 - 3d printed adapter

 - o-ring

 - BTWIN 900 bicycle pump

 - one person holding watch and adapter another pumping the pump

 - used watchmaker pad to protect the crystal (i.e. put watch on it crystal down)
