Wear the most finely crafted and accurate timepiece on the market. Combine atomic accuracy with European style and quality. In 1945, Columbia University physics professor Isidor Rabi suggested that a clock could be made from a technique he developed called atomic beam magnetic resonance. By 1949, what would become the National Institute of Standards and Technology (NIST) announced the world's first atomic clock using the ammonia molecule as the source of vibrations. Later, the element cesium was used. The NBS-4, the world's most stable cesium clock, was completed in 1968 and was used into the 1990s as part of the NIST time system. It was replaced by the F-1, which uses laser beams to measure the photons from the cesium atom.
These clocks and watches truly are synchronizing themselves with the atomic clock in Colorado. This feature is made possible by a radio system set up and operated by NIST located in Fort Collins, Colorado. NIST operates radio station WWVB, which is the station that transmits the time codes. There are no voice announcements on the station, but a time code is synchronized with the 60 kHz carrier and is broadcast continuously at a rate of 1 bit per second using pulse width modulation. The carrier power is reduced 10 dB at the start of each second, so that the leading edge of every negative going pulse is on time. The transmitter range is 1,864 miles (radius) from Fort Collins, Colorado. Your watch will work in most parts of the USA and Canada. You will never have to adjust your watch for Daylight Savings Time (DST) or bother with the date. This is taken care of automatically by the synchronization signal. The accuracy of an atomic watch (radio controlled) watch/clock is unprecedented and absolute.
The G-Force Analog Atomic Watch contains a tiny internal antenna that links to the U.S. atomic clock in Colorado for the most accurate reading. Atomic timing will keep your watch accurate to within one second over one million years. No need to reset for a time change because this beauty springs forward and falls back automatically. It even adjusts when extra seconds are tacked on at the end of a year. The glass is made of scratch-resistant sapphire crystal, and beneath the glass is a stylish analog with the most luminous hands or face (depending on the model) for accurate time-telling in the dark.
