Okay, so again, I'm pretty new at franken but I mis-spoke earlier. The dial opening is indeed 34.5 but the edge where one would think the dial would sit measures 36mm. So, this leads me to believe that what I'm actually missing is the correct movement holder (which in turn would hold everything in it's correct, including the dial).
Any ideas where to source a movement holder? It's a needle in a haystack I imagine, but that's where I am. The case overall is 43mm+ (less the crown) and it has one movement holder notch at 9 o'clock. Possibly a 3777?
