To set the time and date manually
1. In the Timekeeping Mode hold down A until the city
code starts to flash, which indicates the setting screen.
2. Use D and B to select the city code you want.
• Make sure you select your Home City code before
changing any other setting.
• For full information on city codes, see the "City Code
Table".

• Auto DST (

STO, ATH, MOW,TPE, SEL, TYO, HNL, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
NYC, YHZ, or YYT is selected as the Home City code. For more information, see
"Daylight Saving Time (DST)".
• The day of the week is displayed automatically in accordance with the date (year,
month, and day) settings.
12-hour and 24-hour timekeeping
• With the 12-hour format, the P (PM) indicator appears to the left of the hour digits for
times in the range of noon to 11:59 p.m. and no indicator appears to the left of the
hour digits for times in the range of midnight to 11:59 a.m.
• With the 24-hour format, times are displayed in the range of 0:00 to 23:59, without
any indicator.
• The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all other modes.
Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signals transmitted from Mainflingen (Germany), Anthorn
(England), or Fort Collins (the United States) include both Standard Time and DST
data. When the Auto DST setting is turned on, the watch switches between Standard
Time and DST (summer time) automatically in accordance with the signals.
• Though the time calibration signals transmitted by the Fukushima and Fukuoka/
Saga, Japan transmitters include summer time data, summer time currently is not
implemented in Japan (as of 2008).
• The default DST setting is Auto DST (
AvtA
PAR, ROM, BER, STO, ATH, MOW, TYO, ANC, YVR, LAX, YEA, DEN, MEX, CHI,
NYC, YHZ, or YYT as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the city
code starts to flash, which indicates the setting screen.
2. Press C and the DST setting screen appears.
3. Use D to cycle through the DST settings in the
sequence shown below.

Reference
This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Moon Phase Indicator
The Moon phase indicator of this watch indicates the
current phase of the Moon as shown below. It is based on
the view of the left side of the moon at meridian transit
from the northern hemisphere of the Earth. If the
appearance of the Moon phase indicator is reversed from
the actual Moon as viewed from your location, you can
use the procedure under "To reverse the displayed Moon
phase" to change the indicator.

Tidal Movements
Tides are the periodic rise and fall of the water of oceans, seas, bays, and other
bodies of water caused mainly by the gravitational interactions between the Earth,
Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch
indicates tidal movement based on the Moon's transit over a meridian and the lunitidal
interval. The Tide Graph calculates and graphically represents current tide conditions
in your Home City or a port city in the vicinity of the Home City based on longitudes,
lunar day length, and lunitidal interval preset in watch memory, and on high tide times
specified by you.
Tide Graph
The Tide Graph graphically represents the current tide condition using one of three
patterns that represent spring tide, intermediate tide, and neap tide, as shown below.
Tide Name
Graph
Spring Tide
Intermediate Tide
Neap Tide
• The Tide Graph flashes as shown below to indicate the tide range.
High tide
• The segments on either end of the Tide Graph flash during high tide.
Lunitidal Interval
Theoretically, high tide is at the Moon's transit over the meridian and low tide is about
six hours later. Actual high tide occurs somewhat later, due to factors such as
viscosity, friction, and underwater topography. Both the time differential between the
Moon's transit over the meridian until high tide and the time differential between the
Moon's transit over the meridian until low tide are known as the "lunitidal interval".

The information shown in the graphic area depends on the current mode.
