1. Radio technology –The most up-to-date way to keep time
5,000 years have passed since timekeeping began with sundials. In the interim
there have been water clocks, the mechanical clocks of the 13
quartz watches. Now we have the radio-controlled watch.
A watch that in good reception conditions never goes wrong and never has to
be set. The Junghans radio-controlled watch is absolutely precise, as it is linked
by radio frequency to the time control systems of the most accurate clocks in
the world.
For Europe this is the Caesium Time Base at the Physikalisch-Technischen
Bundesanstalt in Braunschweig (Germany's Institute of Natural and
Engineering Sciences).
For North America it is the U.S. Commerce Department's Caesium Time Base at
the National Institute of Standards and Technology (NIST) in Boulder, Colorado.
For Japan the Ministry of Post and Telecommunication's Caesium Time Base at
the Commercial Research Laboratory (CRL).
All of these clocks are so accurate, that they are expected to deviate by no more
than 1 second in a million years.
