    Sweep second hands on a quartz watch?

    Is there some technical reason or is it just convention that quartz watches do not have sweep second hands? It seems to me that it should be possible for a quartz watch to beat at 21000 or 28000 beats like an automatic watch.

    bulova precisionist are quarts and sweep. HowStuffWorks "How the Bulova Precisionist Works"

    The tradeoff to advancing the seconds hand in numerous split second steps is a shortened battery life. The stepper motor is being started and stopped more frequently. However there are a couple of quartz timed options. As noted precisionist has a much smoother seconds hand. And Seiko Spring Drive delivers a smooth seconds hand at a very steep price and with an abbreviated power reserve.

    You may also want to use the WUS search engine for topics like smooth quartz seconds hand. Every facet of the topic has been discussed many times previously.

    I doubt that most people who wear a quartz watch know or care which is possibly a reason.

    Re: Sweep second hands on a quartz watch?

    When quartz watches came out, it was a popular (and expensive) complication in mechanical watches to have them jump by the second even though their actual beat rate was much higher. So, some people clearly would prefer the one-second jumps. I have to admit that I prefer the smoothly-moving hand, though. I find Seiko spring drives almost hypnotic to look at. Snooooooowflaaaaaaaaaake.......

    As noted, you'll find plenty about this through then forum-search feature. However, searching about a "sweep" second hand is going to turn up a lot of topics about second hands that sit in the middle of a dial, since a sweep second hand is formally just the opposite of a "small second" hand that sits in a subdial (notice how John MS carefully avoided using the word "sweep" in his post above). Searches for smooth, gliding, or high-beat quartz second hands will turn up additional threads on the topic.

    Quartz oscillators "beat" at 32K beats per second, not 21.6K per hour. The stepper motor counts the seconds, and has nothing to do with the oscillator other than to move after 32K beats. Why anyone cares about a faster motion on a quartz watch has always escaped me. At one point mechanical watchmakers spent a lot of time trying to get a mechanical watch to have a dead beat motion like quartz.

    Smooth sweeping quartz watces?

    Would you be more into quartz watches if they had a sweeping second hand?

    If you want to get technical, most crystals vibrate at 32,768 cycles/second.

    Thats what it says on the dial of my 1973 SETH THOMAS, quartz watch.
