I recently bought a 4992b without a crystal, missing for some time and dial grubby but not damaged, leading to two issues.
The dial needs cleaning and without knowing the material I am reluctant to try the usual cleaners. can someone tell what material the dial face is?
Secondly the bezel is well and truly tight on the case, left to my own devices I would glue a piece of wood to the bezel and attempt to screw off, (this has worked before), but has anybody anything else to suggest?
Thanks
Peter
