Timekeeping
x Resetting the seconds to 00 while the current count is in the range of 30 to 59
causes the minutes to be increased by 1. In the range of 00 to 29, the seconds are
reset to 00 without changing the minutes.
x The year can be set in the range of 2000 to 2099.
x The watch’s built-in full automatic calendar makes allowances for different month
lengths and leap years. Once you set the date, there should be no reason to
change it except after you have the watch’s battery replaced.
Illumination Precautions
x Illumination may be difficult to see when viewed under direct sunlight.
x Illumination turns off automatically whenever an alarm sounds.
x Frequent use of illumination runs down the battery.
EN-47
Auto Return Features
x If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.
x If you leave the watch in the Moon/Tide Data or Alarm Mode for two or three
minutes without performing any operation, it automatically changes to the
Timekeeping Mode.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a
scroll operation scrolls through the data at high speed.
EN-46
Button Operation Tone
The button operation tone sounds any time you press
one of the watch’s buttons. You can turn the button
operation tone on or off as desired.
x Even if you turn off the button operation tone, the alarm,
Hourly Time Signal, and Timer Mode alarm all operate
normally.
To turn the button operation tone on and off
In any mode (except when a setting screen is on the display), hold down C to
toggle the button operation tone on (
not displayed) and off ( displayed).
x Holding down C to turn the button operation tone on or off also causes the
watch’s current mode to change.
x The indicator is displayed in all modes when the button operation tone is
turned off.
EN-45
x The tide graph displayed by this watch is based on the current Moon age.
Remember that the margin for error of the Moon age displayed by this watch is
±1 day. The greater the error in a particular Moon age, the greater the error in the
resulting tide graph.
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”. When setting the lunitidal interval for this watch, use the time differential
between the Moon’s transit over the meridian until high tide.
EN-44
Tide Graph
The Tide Graph has six graphic segments, each of which indicates a different tide
level. The current tide level is indicated by the displayed graphic segment.
Low Tide
(Rising Tide)
High Tide
(Falling Tide)
Low Tide
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 lunitidal interval differs according to your current location,
so you must specify a lunitidal interval in order to obtain the correct tide graph
readings.
EN-43
x The Moon phase indicator shows the Moon as viewed at noon from a position in
the Northern Hemisphere looking south. Note that at times the image shown by the
Moon phase indicator may differ from that of the actual Moon in your area.
x The left-right orientation of the Moon phase is reversed when viewing from the
Southern Hemisphere or from a point near the equator.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon
appears to wax and wane as the relative positioning of the Earth, Moon, and Sun
changes.

To specify the illumination duration
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
2. While the seconds are flashing, press B to toggle
the illumination duration between 1.5seconds ( ) and
3seconds (
).
3. Press A twice to exit the setting screen.
EN-40
Illumination
The watch has an LED light that you can turn on for reading in the dark.
x See “Illumination Precautions” (page EN-48) for more important information.
To illuminate the display
In any mode, press B to turn on illumination.
x You can use the procedure below to select either 1.5 seconds or 3 seconds as the
illumination duration. When you press B, the illumination will remain on for about
1.5 seconds or 3 seconds, depending on the current illumination duration setting.
