WWVB-RADIO CONTROLLED WATCH
The NIST (National Institute of Standards and Technology-Time and
Frequency Division) WWVB radio station is located in Ft. Collins,
Colorado, and transmits the exact time signal continuously at 60 kHz.
The signal can be received up to 2,000 miles away through the
internal antenna in the La Crosse Technology watch. However, due

2
to the nature of the Earth's Ionosphere, reception is very limited
during daylight hours.
The Watch will search for a signal every night when reception is best.
The WWVB radio station derives its signal from the NIST Atomic
clock in Ft. Collins, Colorado. A team of atomic physicists is
continually measuring every second, of every day, to an accuracy of
ten billionths of a second per day. These physicists have created an
international standard, measuring a second as 9,192,631,770
vibrations of a Cesium-133 atom in a vacuum. This watch is
regulated by the WWVB transmitter.
