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 13th
century and quartz watches. Now we have the radio-controlled watch.
This is a watch that, with good reception, will never go wrong and never need
setting. The Junghans radio-controlled watch is absolutely precise, as it is lin-
ked via wireless technology to the timing control of the most accurate clock
in the world, namely the Caesium Time Base at the Physikalisch-Technischen
Bundesanstalt in Braunschweig (Germany's national institute of natural and
engineering sciences).
