Hey Heuer-fanatics,

since I know that there are many experts in this forum, I want to ask this tricky question: does anybody know which glass can fit a Heuer Calculator? Maybe another Heuer glass could fit, too, or sth. else?
I 've got a Calculator here in perfect shape - except the glass, which really needs to be replaced :-/

I'd love to donate here if somebody was able to give a good hint!

Thanks a lot :)

Best,
Leo
