Re: Can a quartz swing like a mechanical?
Technically, it's just a fine line between what is considered a sweeping hand and those high-bph movements. It's all about what the human eye (and then the brain) can process. Normal mechanicals go up to 10 beats per second, which if you pay attention for you can just barely make out.
That starts to blur once you get over the ~12-ish beat per second mark. The Precisionists also have ticks, they're just so frequent that the human eye can't detect it; something like 16 per second or so. There are some mechanicals which do 20 bps, and if you think stopwatches, some which do 100 bps! The Accutron also had vibrations per second, over 300 iirc.
The Spring Drive, however, is not a 'ticking' movement, because it's regulator is a braking mechanism which keeps proper time. So, if you really want a true sweeping hand, gotta go SD! ;) :lol:
