Atomic Watches: How Do They Do That?

An atomic watch? No, an atomic watch isn't nuclear-powered. An atomic watch is without a doubt the most precise, accurate way to wear time on your wrist. Why? Because an atomic watch periodically receives a synchronizing signal (usually at night) from the Atomic Cesium Clock in Colorado, which is accurate to within one second every million years. Why at night? Although an atomic watch can manually 'reach out' to the synching signal anytime, it's better done at night when the airwaves are less polluted by things such as cell phones.

Atomic watches contain an internal antenna to receive the cesium signal and a program to decode it. You never need to set the time or date on an atomic watch, nor do you have to adjust an atomic watch for daylight savings time. Until atomic watches come with GPS (Global Positioning), you will need to adjust when travelling to a different time zone. This is no big deal-- once you're in a new zone just tell your atomic watch to synchronize itself and it will.

You might guess that an atomic watch comes with an assortment of wink-wonks and you'd be correct. Consider for instance the Casio G-Shock GW1000DJ-9 Atomic Solar Watch, available right here at watchesgiant.com The G-Shock atomic watch not only keeps perfect time, it collects energy from sunlight (or bright room light) so you never have to wind it or replace its battery. The G-Shock atomic watch can display time in twelve or twenty-four hour format. It comes with a stopwatch, five daily alarms, a thirty-city world clock, automatic calendar and is waterproof to 200 meters.

If keeping the most accurate time possible is vital to you, by all means get yourself an atomic watch.
