    Re: Chronometers after radio time signals

    I check the rate of all my watches periodically. I bought a Torgoen dual time zone watch for about $175.00 on October 12, 2004, three years ago, and, so far, it has gained only 14 seconds, and the rate has been very consistent. This would be enough to put a longitude determination off by only three and a half nautical miles on a three year circumnavigation! I don't know if all of their watches are this accurate (I may have just gotten lucky) but this is the most accurate watch I have ever seen.

    no longer needs to be reliable for weeks at a time.
    So did any chronometer
    manufacturers go under after about 1905??
          
    In fact I was always puzzled how chronometers
    survived to the second half of XX century.
    They should have been all trashed when daily radio
    checks became available:-)
    To maintain time between two daily broadcasts
    all you need is a moderately priced wristwatch
    or a pocket watch.
        
    
    Now with quartz crystal wrist watches, you don't especially need the
    radio.
