Current Time Setting
This watch automatically adjusts its time setting in accordance with a time calibration
signal. You can also perform a manual procedure to set the time and date, when
necessary.
The first thing you should do after purchasing this watch is to set your Home City,
which is the city where you will normally use the watch. For more information, see
To set your Home City below.
When using the watch in an area that is outside of the range of the transmitters in
Rugby and Mainflingen, you need to manually adjust the time as required. See
Timekeeping for information about manual settings.
The analog time of this watch is synchronized with the digital time. Because of this,
the analog time setting is automatically adjusted whenever you change the digital
setting. See Analog Timekeeping for more information.
To set your Home City
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
The second hand will move at high speed to the 12
oclock position, where it will stop.
2. Use D (east) and B (west) to select the city code you
want to use as your Home City.
The following are the city codes for major cities in the
Western Europe time zones.
LON: London
PAR and BER: Paris, Berlin, Milan, Rome,
Amsterdam, Hamburg, Frankfurt,
Vienna
ATH: Athens
3. Press A to exit the setting screen.
The second hand will advance at high speed to the
correct position in accordance with seconds count of the
digital time, and resume normal movement from there.

City code
Normally, your watch should show the correct time as soon as you select your Home
City code. If it does not, it should adjust automatically after the next auto receive (in
the middle of the night). You can also perform manual receive or you can set the time
manually.
If you are in an area that does not use Daylight Saving Time (summer time), turn off
the DST setting.
The watch will receive the time calibration signal automatically from the applicable
transmitter (in the middle of the night) and update its settings accordingly. For
information about the relationship between city codes and transmitters, see
Transmitters.

In the Timekeeping Mode, press A to cycle through the digital time screens as

I had a new battery put in my 4379. Afterwards the date screen correctly updates each day, but the hands are 1hr 10 min behind what they should be. Pressing any of the buttons does nothing at all so I cannot correct the hands.
