I find it puzzling that people are so obsessed with how smooth second hand sweeps across the dial. I have had a variety of movements in my watches over the years from 3Hz. Seiko, ETA Powermatic and Orients all the way up to a 36k El Primero. The smoothness in the higher beat movements is completely lost on me. In fact, it reminds me of the electric cafeteria clocks we all had in grammar school that said Westclox, General Electric, or Ingraham on them. Those second hands were absolutely smooth. So the smoothness of the sweep doesn't evoke quality to me necessarily.
Is it important to you. If so, why?
