Robert, those have all the tell-tale signs of Asian movements. It's not just the flared-spoke balance wheels. It's the lack of the "dimple" on the small block where the mainspring connects to the regulator, as well as the overall finish of those movements.
I wait to be proven wrong, but until I am, I have to say that I believe those are 100% A6497s. I have never before seen an ETA 6497 that had the flared spoke balance wheel and was missing the "dimple" on the mainspring connector, etc.
