You may be forgetting that radio time signals are not always available everywhere all the time. Near the U.S, WWV and WWVH have reliable coverage but there are parts of the world where this is not true, even today. Of course, now, accurate time is always available everywhere on earth via the GPS, but that is another story.

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. Alex.
