ABOUT NIST
The RCW utilizes a highly sensitive radio receiver to automatically set the time and date. The National Institute of Standards and Technology (NIST) measures each second of time as 9,192,631,770 vibrations of a Cesium 133 atom in a vacuum. The measurement of the Cesium 133 atom is accurate to one second every one million years. The time is then transmitted from Fort Collins, CO to the rest of the United States (US). NIST is the official time used by the US; it governs ship movements, radio stations, and space flights. The RCW
This watch should be set manually for the first time. After that, the watch will automatically adjust itself to maintain accurate time.
SETTING THE TIME ZONE
The RCW will automatically set the time and date when a NIST signal is received successfully. However, you will still have to set the correct time zone.
(Note: The RCW will not automatically adjust to a new time zone if you are traveling. You must change the time zone setting to continue to keep the exact time.)
