Ref F6231 Crystal help

xorl · Jan 15, 2026

Hello All!

New around here but reading around this place seems like the best spot for the help! I have a F6231 Cal 344 Bumper from 1952, I have a crystal already but it is worse for wear. I doubt I'll find a better one but googling for the part number has yielded too many mixed results. Figured I'd ask here in case someone knows a model number or what to look for in a crystal replacement.

Thanks again!

Should have said, I also measured the diameter of the case where the crystal would go and it's 29mm and 29.2 on the opposite axis. Would a generic acrylic work for this and is it double domed or regular? And should I get a 29.4? Any tips would be recommended.

Alright, after doing some more hunting on google (somehow the search didn't find this gem) I came across this post https://omegaforums.net/threads/omega-bumper-crystal.161251/ which if my measurements are right, the model number there is what I will probably not be finding, going to try a generic 29.2.
