Liberty watch corp movement runs face down only!

[cduke]

Hello all,

I have a vintage Liberty watch corp , one jewel, unadjusted movement that is a pin lever type similar to a Lapanouse movement that only runs on it's belly  (face down).

Obviously, the stem must be faulty, but it runs so perfectly face down that I've considered putting it on a glass shelf above my head :)  Any fixes to try before trying to find a new balance wheel assembly?

Thank you

I think I only now noticed the one jewel is missing.  The culprit?  How is the jewel size determined?

Thanks
