I ended up flipping by Bulova Precisionist ("Continuous sweep second hand, under the loupe the 16 steps per second can be seen easily) because it weighed something like 235 grams and after a long day it just got tiresome.Phew! Though I was a bit odd getting hung up on the sweep hands smoothness, glad not to be the only one, just bought an Oceanaut Seven Seas with an ETA 2824 movement.
Big watches with long second hands show up the lesser frequencies more.
It's still a virgin watch and bagged it for a song, and as it weights a arm stretching 260gms(8oz if your really old)! I can cancel the gym membership.......!!!!
