T&T: Atomic watch

[tbehan6468 at aol.com]

I have been using?two atomic desk clocks (Emerson?Research)?for SEVERAL years?that receive the signal, first when I lived in Iowa, and now in Florida (Orlando area). Thye've always worked fine. I also have a Radio Shack atomic travel alarm clock that I keep on my boat (Punta Gorda) and it also does great. But by far the best of the bunch is my Casio atomic wristwatch. Solar powered w/battery, all the normal time zones, beeps, alarms, counters, plus a calendar AND soft blue backlighting at the touch of a button. It talks to the Big Atomic Clock in Colorado several times every night automatically, and resets itself to match it if needed. I can push a button and it will flash the date and time of the last interrogation - that's how I know it works.?Just for kicks I've pulled up the Atomic Clock web site from Colorado (Colorado Springs I think) and compared my wristwatch to it and they always match EXACTLY, even to when the seconds change. And this watch cost all of around $70-80
  two years ago at Wal-Mart.

If I remember correctly, it's easier for these low power watches to receive the signal at night - less interference. That's why they do their resets at night.

The National Geographic Xmas gift catalog advertises an "Atomic" clip  
watch for $60 that sets the time to a thousandth of a second accuracy  
by receiving the WWV transmissions form Colorado. While I don't use  
my sextant for navigation any more, 30 years ago a watch of this  
precision would have been a welcome replacement for much more  
expensive chronometers.

What I would like to know is how far the WWV signal carries. I can  
receive WWV on a cheap shortwave receiver in upstate NY. Could I get  
it in Hawaii or in Europe? I know that there are broadcast time  
reference signals all over the world but I don't know if any "Atomic"  
watches pick them up.

All this is just for curiosity. I'm satisfied with the accuracy of my  
old Timex and I don't intend to give up my GPS.
