1. Radio technology - The most up-to-date way to keep time

5,000 years have passed since timekeeping began with sundials. In the inte-
27
rim there have been water clocks, the mechanical clocks of the 13th century
28
and quartz watches. Now we have the radio-controlled watch.
30
A watch that in good reception conditions never goes wrong and never has to
31
be set. The Junghans radio-controlled watch is absolutely precise, as it is linked
33
by radio frequency to the time control systems of the most accurate clocks in
34
the world.

For Europe this is the Caesium Time Base at the Physikalisch-Technischen Bun-
36
desanstalt in Braunschweig (Germany's Institute of Natural and Engineering
37
Sciences).

For North America it is the U.S. Commerce Department's Caesium Time Base at
40
the National Institute of Standards and Technology (NIST) in Boulder, Colorado.

41
For Japan the Ministry of Post and Telecommunication's Caesium Time Base at
43
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.
