• Even if you turn off the button operation tone, the
alarms, the Hourly T

To turn the button operation tone on and of
In any mode (except when a setting screen is on the
display), hold down C to toggle the button operation tone
on (mute indicator not displayed) and off (mute indicator
displayed).
• Holding down C to turn the button operation tone on or
off also causes the watch’s current mode to change.
• The mute indicator is displayed in all modes when the
button operation tone is turned off.
Auto Return Features
•
•
• If you leave the watch in the Tide/Moon Data or
without performing any operation, it automatically changes to the Timekeeping
Mode.
• 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.
Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data on the display
operation scrolls at high speed.

Timekeeping
•
•
• 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.
• The year can be set in the range of 2000 to 2099.
• 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.
World T
All World T
Timekeeping Mode using UTC of
• The seconds count of the World T
Timekeeping Mode.
• The UTC offset is a value that indicates the time difference between a reference
point in Greenwich, England and the time zone where a city is located.
• The letters “UTC ” is the abbreviation for “Coordinated Universal T” , which is the
world-wide scientific standard of timekeeping. It is based upon carefully maintained
atomic (cesium) clocks that keep time accurately to within microseconds. Leap
seconds are added or subtracted as necessary to keep UTC in sync with the Earth’s
rotation.
Illumination Precautions
• The electro-luminescent panel that provides illumination loses power after very long
use.
• Illumination may be hard to see when viewed under direct sunlight.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery

Flash Alert indicator
About the
While the auto light switch is enabled, illumination turns on whenever you position
your wrist as described below in any mode.
Moving the watch to a position that is parallel to the ground and then tilting it
towards you at more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.
W
• Always make sure you are in a safe place whenever you are reading the watch
using the auto light switch. Be especially careful when running or engaged in
any other activity that can result in accident or injury
sudden illumination by the auto light switch does not startle or distract others
around you.
• When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create
a distraction, which can result in a traffic accident and serious personal injury
To turn the auto light switch on and of
In the TB for about three seconds to toggle the auto
light switch on (auto light switch indicator displayed) or off (auto light switch indicator
not displayed).
• The auto light switch indicator is on the display in all modes while the auto light
switch is turned on.
• In order to protect against running down the battery
automatically approximately six hours after you turn it on.

Moon Phase
Moon phase (part you can see)
• 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.
• 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
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. The greater the angular distance between the Moon and the Sun,* the more
we see illuminated.
*
The angle to the Moon in relation to the direction at which the Sun is visible from the
Earth.
This watch performs a rough calculation of the current Moon age starting from day 0
of the moon age cycle. Since this watch performs calculations using integer values
only (no fractions), the margin for error of the displayed Moon age is
±1 day

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. T
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.
• 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
resulting tide graph.
Lunitidal Interval
Theoretically’ s transit over the meridian and low tide is about
six hours later
viscosity
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.
