    Re: Chronometer Suggestions

    Hello Bill
    A word to the wise...if you are looking for an accurate time piece , a
    chronometer is not it..as you know they are rated over a period of time and
    the error ,say per day or week, is noted as a correction....and this
    correction only is valid when the unit is kept at a more or less constant
    temp.etc. I have two chronometers (both Thomas Mercer)(Hamilton is more or
    less the USA version) and ,years ago spent countless weeks trying to correct
    the "rating" (either for + or -) to say a second /per week, all under ideal?
    (home) conditions Finally gave up .Tried using a few of my "deck
    watches"..set to WWV and found errors just going from W. Van to Dundarave
    Park again using WWV.
    My humble advice is to use a short wave radio (WWV or CHU..etc) and two
    column form "time" and hs. Say taking a sight every 30 seconds. It's quick
    simple and ,if you are neat, foolproof.
    Hope I have not over done this msg.

    I presently use the radio time signals or the internet to check or sync my
    cheap quartz wristwatch for navigation calculations, and I also have a cheap
    watch that picks up WWV when it is in the mood.  I find my trusty Timex is
    off about 6 seconds a month, but I was wondering if there are any reasonably
    priced real quartz chronometers (non-wrist) that anyone would recommend?  I
    use the word real since the word chronometer is tossed about by the
    marketing people without any regard
    to it's strict real meaning, which has been posed here at least once.
    I would be happy with a settable second hand and some sort of temperature
    compensation. Apparently, the picky can pick up a used atomic clock on e-bay
    these days, but I am looking for a happy medium.
    If I found one, would a Hamilton Chronometer still be reliable or have too
    many years passed?
