1. Radio-controlled technology – It doesn’t get more accurate.
Junghans and a delight in innovation go hand in hand, as is shown
by over 3,000 patents submitted over the course of the company’s
history. In 1956, we were the world’s third-largest producer of chro-
nometers. No reason to be satisfied with what we have achieved, but
rather an incentive to become ever better. Thus, in 1970 we developed
the first German quartz watch and in 1990 the first radio-controlled
wristwatch. The Junghans radio-controlled wristwatch is absolutely
precise, as it is linked via radio-controlled technology to 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 the
UK the time signal comes from three atomic clocks installed at
the transmitter site in Anthorn, Cumbria, and is based on the time
standard of the National Physical Laboratory (NPL) in Teddington.
For Japan the Caesium Time Base of the National Institute for
Information and Communications Technology (NICT), a public admin-
istration authority organisation. 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. Its time
information gets checked against over 60 time institutes around the
globe at the Bureau International des Pois et Mesures (BIPM) in Sévres
near Paris. Thanks to its stylish, classic design you have with the
Junghans MEGA not only the world’s most accurate time, but perhaps
the most beautiful as well.
