The movement is very nice to watch, the jerkiness is just barely perceptible at high speed. On the other hand 28,800bph mechanicals jitter visibly without slow motion capture. Since the spring drive is on some level imperceptibly smooth, I'd say it's a Retina-style improvement over the jitters.
- gleam 12y agoI own one, and here's my own slow motion video: http://youtu.be/tQUMl9NMb8Q http://youtu.be/tQUMl9NMb8Q There shouldn't be much or any perceptible jerk. The glide wheel never actually stops, it's just slowed down a little bit eight times per second. Accuracy is superb compared to a mechanical watch; mine has lost 3 seconds in the past ten months. I also own a vintage accutron tuning fork movement. The second hand on that ticks 300 times per second, and is visually identical to the sweep of a spring drive movement. A very cool movement, too.
