I just needed to remove bezel and got advice of watchmakers forum which worked on two of my Autavias. Basically hold case in one hand and with other hand put three finger on bezel then pull and twist at same time and bezel should come off. If its not too tight to begin with it will come off easily. Hope that is helpful. I'm not a pro so someone may have better advice but it worked for me and hands do less damage than wrong tools!
