Howdy,
I'd like to remove the Hermetic case back. What type this back is: snap-on or screw-on? I have tried to use thin-bladed knife but w\o success.

:( :( :( looks like a snap on--no tool notches around back. sometimes they are really tough to remove.see if a local watchmaker can do it. with a knife you CAN hurt yourself--from MY experience! good luck, JON
Thanks a lot - will give them to the watchmaker! They are the first watches I'm facing such a problem with. Yeah, Zodiac - are quite unique watches ;D
Merry Christmas and Happy New Year!
