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.
