I do think a brand new watch should be timed so the index regulator is centered, and it's a bit of a letdown to see the majority of the new 321s not adjusted to this standard, especially when Omega touts that each watch is fully assembled, and presumably timed, by one experienced watchmaker in the dedicated 321 assembly room. Mine is set about 2/3 of the way toward the first index mark to the 'R' side. But I wonder when Omega made untold thousands of 321s in the 50's and 60's what was the standard, were the index's centered or were they done in a similar fashion that we see now, tweaked one way or the other to get a good rate? All of them were hidden behind closed backs so it wouldn't be something that would be seen except by a watch repairer over the years. Perhaps Omega is just following the same practices that were used back in the day. Or not.
