I'm trying to do some research on older speedmasters, and I would like to know if anyone could help with a franken project question. I'm lookign for a movement to fit the 3-6-9 configuration on the speedmaster. Were the seconds at 6 on the gen? I'm trying to find out what movement I could slap in there instead of a Gen omega caliber 861. Is it a moniker for a generic valjoux movement, or could there be a company with something that could fit (the way Poljot copied the 7734). Thanks for any info.
