An Atomic Watch is a wrist watch that is radio controlled to keep the most accurate time on earth. Receiving low frequency radio signals each night from the government run US Atomic Clock in Colorado, you will not ever have to set your watch again as it will keep exact synchronized time with the Atomic Clock at the National Institute of Standards and Technology. It's about as accurate as you will get - the Atomic Clock that is used to set atomic watches has been tested with mathematicians have declared that the clock to be accurate to within less than one second each thirty million years! Your atomic watch will even adjust automatically to Daylight Savings, leap years and unbelievably even leap seconds. An internal antenna is programmed to seek once every day for the 60kHz radio wave that is transmitted from the Ft. Collins Atomic Clock. As the the frequency is picked up, the time is deciphered then reset. The Ft. Collins transmitter has a radius of 1864 miles (3000km), making it available to the most of the United States with the exception of Hawaii and Alaska. You will still have to reset your watch manually if you cross time zones. Your watch is programmed to decipher the radio signals it receives in the time zone it is in, your watch contains programming for each state and time zone in the USA so you need to select the time zone you are in manually then the watch will do the rest, until GPS is integrated into atomic watches. With technological advances I doubt this will be too far away. What happens if my watch can't pick up the signal, will it still function as a watch? Yep! With battery or solar powering your watch it will still tell the time but as it won't have picked up the radio frequency from the atomic watch it won't be telling the synchronized exact time. Things that will affect your atomic watches ability to pick up the radio signal may include a very large building, having placed your watch in a safe, being next to electronic items emitting interference or being too close to power lines . Saying this though, your atomic watch will of course carry on seeking the radio frequency signal every night and will continue to run incredibly accurately even if it only manages to pick up the signal a couple of times a week. While your watch will work perfectly well as a quartz watch when you travel overseas it will not be receiving the radio signal to update the time. Europe does have Atomic clocks but the frequency differs to that used in the US though some of the more expensive atomic watches do contain the ability to read these frequencies. Offering a good range are two very well respected makers of watches - Atomic watch Casio and Maximilian.
