there is no doubt in this and as mrfog mentioned the smooth running of the watch is unmatched except by maybe a Seiko Spring Drive or high beat GS, I have neither of those and have only seen them in videos.
I'll clarify this point because..well we're watch nerds.
A21J runs at 6 beats per second = 21600 bph
2836-2, Rolex etc. runs at 8 bps = 28800 bph
Grand Seiko runs at 10 bps = 36000 bph
Bulova Presisionist runs at 16 bps = 56000 bph
Spring Drive does not have beats, the second hand is constantly mechanically braked in sync with time.
I love my Bulova and got it dirt cheap off ebay, like almost 1/4 rrp so I am over the moon with it.
You really have seen nothing like the sweep until you see it in person.
Of course it may not be finished as well as a Tag or Omega but those watches are not finished as well as a Breguet or a Greubel Forsey.
Horses for courses.
