•The GMT differential is the time difference of the time zone where the site is located
from Greenwich Mean Time.
• Note that you must add one hour to the GMT differential for your time zone
whenever you change to Daylight Saving Time. Subtract one hour when you change
back to Standard Time.
• The lunitidal interval is the time elapsing between the Moon’s transit over a meridian
and the next high tide at that meridian. See “Lunitidal Interval” for more information.
• This watch displays lunitidal intervals in terms of hours and minutes.
• The “Site/Lunitidal Interval Data List” provides GMT differential, longitude, and
lunitidal interval information around the world.
• The following is the initial factory default Home Site data (Tokyo, Japan) when you
first purchase the watch and whenever you have the battery replaced. Change these
settings to match the area where you normally use the watch.

•All of the operations in this section are performed in the
Bearing Mode, which you can enter from the
Timekeeping Mode by pressing  B.
Important!
Before the watch can calculate the solar azimuth (the
angle of the sun in relation to your location) correctly, you
must first set the correct current time, current date, and
Home Site in the Timekeeping Mode. You must also
specify whether the sun traverses the sky to the north or
to the south of your current position.Solar azimuth
• Note that you cannot use the Bearing Mode to determine directions in the following
cases.

Countdown TimerThe countdown timer can be set within a range of one
minute to 60 minutes. An alarm sounds when the
countdown reaches zero. The countdown timer has two
modes: auto-repeat and elapsed time, and a progress
beeper signals the progress of the countdown. All of this
makes the countdown timer a valuable tool for timing the
start of a yacht race.
•All of the operations in this section are performed in the
Countdown Timer Mode, which you enter by pressing

Reset Time
Yo u can set a “reset time,” which is a kind of alternate countdown start time you can
recall with the press of a button any time a countdown operation is in progress.
Timer Mode
The countdown timer gives you a choice of two modes: auto-repeat and elapsed time.
A uto-repeatAu to-repeat automatically restarts the countdown from the countdown start time
whenever zero is reached.
• Auto-repeat mode is best when timing the starts of match races.
• Even if you start a countdown operation from the reset time, the countdown
automatically restarts from the countdown start time whenever it reaches zero.
• Auto repeat timing repeats up to seven times.
Elapsed TimeWhen the end of the countdown is reached in the elapsed time mode, the timer
automatically switches to an elapsed time measurement operation.
• The elapsed time mode is best when timing the speed of yachts during ocean races.
• The elapsed time operation is performed in one-second increments up to 99 hours,
59 minutes, 59 seconds.
Countdown Timer Beeper OperationsThe watch beeps at various times during a countdown so you can keep informed
about the countdown status without looking at the display. The following describes the
types of beeper operations the watch performs during a countdown.
Countdown End Beeper
The watch beeps each second of the final 10 seconds before a countdown reaches
ze ro, and at zero. The first five beeps (seconds 10 through 6) are higher pitched than
the final five beeps (seconds 5 through 1). The watch emits a longer beep to signal
when the countdown reaches zero.
• The countdown end beeper always sounds, regardless of the on/off status of the
progress beeper.
Progress Beeper
The progress beeper actually includes two beepers: a reset time beeper and a reset
period progress beeper.
• The reset time beeper and reset period progress beeper sound only while the
progress beeper is turned on.
Reset Time  BeeperThe reset time beeper is similar to the countdown end beeper. When the progress
beeper is turned on, the watch beeps each second of the final 10 seconds before the
countdown reaches the reset time.
Reset Period Progress BeeperThe reset period is the portion of the countdown between the reset time and zero.
When the progress beeper is turned on, the watch emits four short beeps at the top of
each minute during the reset period, and 30 seconds before the end of the
countdown.

ReferenceThis 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 IndicatorThe Moon phase indicator of this watch indicates the current phase of the Moon as
shown below.Moon Phase

•
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 Age
The Moon goes through a regular cycle that averages 29.53 days. 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 v\
isible 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 ±3 days.
Tide GraphThe black bars on the watch’s tide graph indicate the current 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.
High
tideLow
tide
• 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 ±3
days. 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.
A uto Return FeatureIf you leave a screen with flashing digits on the display for two or three minutes without
performing any operation, the watch automatically saves any settings you have made
up to that point and exits the setting screen.
ScrollingThe  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.
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.
• With the 12-hour format, the  P (PM) indicator appears on the display for times in the
ra nge of noon to 11:59 p.m. and no indicator appears 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 year can be set in the range of 2000 to 2039.
• 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•Illumination may be hard to see when viewed under direct sunlight.
• Illumination automatically turns off whenever an alarm sounds.
• Frequent use of illumination runs down the battery. Auto 
light switch precautions
• We aring the watch on the inside of your wrist, movement of your arm, or vibration of
y our arm can cause frequent activation of the auto light switch and illumination of the
display. To avoid running down the battery, turn off the auto light switch whenever
engaging in activities that might cause frequent illumination of the dis\
play.
More than 15 degrees
too high• Illumination may not turn on if the face of the watch is
more than 15 degrees above or below parallel. Make
sure that the back of your hand is parallel to the ground.
• Illumination turns off in about one second, even if you
ke ep the watch pointed towards your face.
• Static electricity or magnetic force can interfere with
proper operation of the auto light switch. If illumination
does not turn on, try moving the watch back to the
starting position (parallel with the ground) and then tilt it
back towards you again. If this does not work, drop your
arm all the way down so it hangs at your side, and then
bring it back up again.
• Under certain conditions, illumination may not turn on until about one second after
you turn the face of the watch towards you. This does not necessarily indicate
malfunction of the auto light switch.
• Yo u may notice a very faint clicking sound coming from the watch when it is shaken
