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.

MOW*

: Moscow, Jeddah, Kuwait, Riyadh, Aden, Addis Ababa, Nairobi

signal transmitters, and so certain conditions may cause problems with signal
reception.

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”.

Time Calibration Signal Reception

There are two different methods you can use to receive the time calibration signal:
auto receive and manual receive.

Auto Receive

With auto receive, the watch receives the time calibration signal automatically up to
six times a day. When any auto receive is successful, the remaining auto receive
operations are not performed. For more information, see “About Auto Receive”.

Manual Receive

Manual receive lets you start a time calibration signal reception with the press of a
button. For more information, see “To perform manual receive”.

Important!

When getting ready to receive the time calibration signal, position the watch as
shown in the nearby illustration, with its 12 o’clock side facing towards a window.
Make sure there are no metal objects nearby.
