EDIT: Resolved. I just very gently pried it and it worked. Hope I'm asking in the right place. I have an old Armourlight Isobright with I believe Ronda 715Li movement. How the hell do you get the old batt out and the new in?It has this plastic retainer but I don't see an obvious way to remove it. Don't want to risk prying. Yes, I know it is dusty inside. Thanks for any help.
