I find with my automatics, they are somewhat sensitive to what is happening in their environment. For example, I get repeatably different behaviour between wearing it at night, taking off and placing face up on nightstand, and taking off and placing face down on nightstand. I suspect this holds true for most reasonably priced automatic movements. All that to say that if your seeming obsession with exactly correct time keeping is a hobby, then all the more power to you. I know I wear and love automatics because I find all the teeny tiny gears, springs and moving parts both fascinating and involving. My favourite Seiko is accurate to within about 2 - 2.5 minutes a month and that is plenty accurate enough for me. I verify it occasionally, and reset it either when I need to reset the date or when it is out by more than a couple minutes. If I really need to know the exact time, I can check my phone or computer since both sync to very accurate network clocks. Having said that there are almost zero events in my life that need more accuracy than that which my watch provides. However, if you really need really accurate time keeping, either due to job requirements, or a personal foible (and believe you me, I understand foibles) you are not going to ever be happy with automatics... just move on to a good atomic clock syncing digital and breath a sigh of relief.
