    Re: Question from the FNG

    The practical answer is yes. A number of the members including myself have checked various quartz watches and the rate is quite stable. The only proviso is that a quartz movement is sensitive to temperature. The really high percision quartz watches have a temperature compensation feature to help get them to that <10 seconds error per year or better.

    There is a good article on the NIST WWVB Station Library website; "How Accurate isa Radio Controled Clock"  https://www.nist.gov/pml/time-and-frequency-division/radio-stations/wwvb/wwvb-station-library

    Well worth the read and covers several aspects of quartz watch accuracy.

    Cheers,

    Jim
