Your Junghans MEGA is equipped with a multi-frequency radio-con-
trolled movement. The watch is able to pick up the signals automati-
cally from the following time signal transmitters:
– DCF77 in Mainflingen (24 km south-east of Frankfurt am Main) for
Europe
– MSF in Anthorn, Cumbria for the United Kingdom
– JJY40 on Mount Ohtakadoya (near Tokyo in the North East of the
country) for Japan
– JJY60on Mount Hagane (in south western Japan) for Japan and
South Korea
– WWVB in Fort Collins, Colorado (USA) for North America
Within these 5 transmitter zones the Junghans MEGA shows the pre-
cise radio-controlled time as long as a successful time synchronisation
has taken place.
If the automatic time synchronisation is disturbed by the weather
or by environmental influences (e.g. storms, electrical appliances or
dimmer switches), the Junghans MEGA automatically starts a new
synchronisation attempt at the same time the next day. Manual
synchronisation can be initiated at any time by pressing the corrector
corrector button.
With the Junghans MEGA, switching between summer and winter
time happens automatically in the DCF77 and MSF zones. If you travel
to a country in a different time zone, the time zone setting facility
makes it easy to set your watch to the appropriate local time, accurate
to the second.
Cutting edge technology for absolute precision
The radio-controlled movement of your Junghans MEGA is equipped
with cutting edge technology that in addition to radio-controlled time
provides absolute precision:
• The ITC (Intelligent Time Correction) technology synchronises the
position of the second hand against the most recently received time
information 1,440 times a day. In addition, the position of hour and
minute hands gets checked daily and the position of the date once
a month. If necessary, e.g. after a shock or interference from a mag-
netic field, a correction is made.
• Precise indication of the seconds is guaranteed by the SHM (Smart
Hand Motion) technology, which enables the seconds to be dis-
played in half-second steps.
• The Advanced Moving Function (AMF) controls second hand, minute
hand and date display using ultramodern technology. The move-
ment of the date/hands is triggered fractions of a second before the
time changes. As a result what is shown is the actual time – without
any delay at all.
• Even without time synchronisation the time shown is always
extremely accurate The time deviation range that is possible in
quartz mode has been minimised to +/– 8 seconds a year. When
worn normally, the watch’s actual deviation is thus 8 seconds a year
at most.
• Your Junghans MEGA has a perpetual calendar. Subject to suc-
cessful time synchronisation, it never needs to be corrected. In the
