Yeah that’s true. I guess the 321 had a short production run and has gone through an evolution. I think the “First Omega in Space” as this numbered anniversary run is called, sports a caliber 1861, which as much as I can gather is newer and more reliable version of the 321. But of course not as much of an collectors item.
This is getting pretty nerdy, but here a video of just how complicated and precise these movements are like the Caliber 1861 in the video.
Anyway, I actually pulled the trigger on this guy. Good to know that it won’t be the watch that’s holding me back from going to space
