    The "atomic" watches are not good outside of specific areas.  I inquired about that when i was in the mood to not have to reset my watch.  The 60 Hz signals are strongest in the USA, Japan area, and Europe.  Elsewhere, including most of the oceans, the signal will not get to the watch most of the time, and you lose that feature.  You are better off with a decent quartz movement, and checking it against a radio time tick which has better range on the HF bands.

    Douglas,

    Well' I'll be darned.  I had no idea that the GPS receiver display
    could be off by seconds.  I naturally thought that, with atomic clocks
    onboard the satellites, the receivers would be displaying atomic-clock
    accuracy.  Thanks for setting me straight.  Actually, I have been
    checking my Timex against a small WWVB clock which receives 60Khz time
    signals from near Fort Collins, Colorado.  Does anyone know how this
    60Khz signal strength is world wide??

    There's also the NIST website at  http://nist.time.gov/timezone.cgi?Central/d/-6/java
    which claims 0.2 second accuracy.  Is that accuracy statement
    reliable??
