At the very least, it reassures me to see that the bulk of my concerns is based on what amounts to a general consensus among collectors on these watches. I readily admit that I know next to nothing about most vintage Heuers, but the Lemania 5100 powered models are the notable exceptions given the fact that I've been tracking down these watches for many years now.

I've also noticed this morning another puzzling detail about the particular watch being debated: it has black day and date wheels, a feature I had never seen before on a civilian Lemania 5100 Heuer.
