    Radio-controlled clock and watch updates are very much dependent upon the time of the day and where you are. In NY and New England it is hit or miss from day to day. NIST has a nice set of coverage maps here:

    I have a unit marketed under the Sharp brand that I picked at Wal Mart. More
    than $6 dollars.  It claims to poll once a day, about 1 am local time.  It
    has failed to make an automatic connection for over two years.  Positioned
    as directed, and manually triggered at the recommended time as well as other
    times, it has made a connection twice in over 500 tries.

    A sailing acquaintance with more money than common sense (center cockpit 42'
    sailboat) has a wristwatch that cost several hundreds dollars and claims to
    poll the clock six times a day.  He is not sure how well it functions as the
    plastic band it came with broke the first month and he has not bothered to
    replace the watch band.

    For what it is worth.
