I pronounce Favre Leuba the same way CometHunter does.

 

[CometHunter]

I see that FAVRE made it in but LEUBA didn't. I can imagine three options - LURBA, LOYBA or LAYUBA. Any advance?

No idea what you were looking at, but I think I got it filled-in! :laugh:
Best wishes with your quest.
The good news is: if one of our watchmakers doesn't answer your question, at least F-L movements are dirt cheap. But a spare or two, dive in with your screwdrivers, and try to fix it yourself!
