Don't quote me on that movement description. I'm no watchmaker and didn't even play one in the high school senior play. ETA was said to be a major component of Doxa watch production in the 1950s/early 1960s.
We're about 95% packed for our relocation from Los Angeles to the SF Bay Area, including the packing of watches and associated paraphernalia. So it seems everything's been reduced to just the essential 😀
