Charging the Watch
The face of the watch is a solar cell that generates power from light. The generated power charges a
built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed
to light.
Charging Guide
Whenever you are not wearing the
watch, leave it in a location where it
is exposed to light.
•Best charging performance is
achieved by exposing the watch to
the strongest light available.
When wearing the watch, make sure
that its face is not blocked from light
by the sleeve of your clothing.
•The watch may enter a sleep state
(page E-14) if its face is blocked
by your sleeve even only partially.
Warning!
Leaving the watch in bright light for charging can cause it to become quite hot.
Take care when handling the watch to avoid burn injury. The watch can become particularly hot
when exposed to the following conditions for long periods.
•On the dashboard of a car parked in direct sunlight
•Too close to an incandescent lamp
•Under direct sunlight
E-10
Important!
•Allowing the watch to become very hot can cause its liquid crystal display to black out. The
appearance of the LCD should become normal again when the watch returns to a lower temperature.
•Turn on the watch’s Power Saving function (page E-14) and keep it in an area normally exposed to
bright light when storing it for long periods. This helps to ensure that power does not run down.
•Storing the watch for long periods in an area where there is no light or wearing it in such a way that it is
blocked from exposure to light can cause power to run down. Expose the watch to bright light
whenever possible.
E-11
Power Levels
You can check the current battery power level by viewing the battery power indicator that appears on the
digital display when you enter the Timekeeping Mode.
•To enter the Timekeeping Mode from any other mode, hold down Dfor about two seconds.

•The flashing
Lindicator at Level 3 tells you that battery power is very low, and that exposure to bright
light for charging is required as soon as possible.
•At Level 5, all functions are disabled and settings return to their initial factory defaults. Once the battery
reaches Level 2 (
M) after falling to Level 5, reconfigure the current time, date, and other settings.
•Display indicators reappear as soon as the battery is charged from Level 5 to Level 2 (
M).
•Leaving the watch exposed to direct sunlight or some other very strong light source can cause the
battery power indicator to show a reading temporarily that is higher than the actual battery level. The
correct battery level should be indicated after a few minutes.
•All data stored in memory is deleted, and the current time and all other settings return to their initial
factory defaults whenever battery power drops to Level 5 and when you have the battery replaced.
Charging Required Indication (by second hand)
When battery power reaches Level 3, the second hand of the watch will
jump at 2-second intervals in the Timekeeping Mode to let you know that
charging is required.
Power Recovery Mode
•Repeated sensor measurement, illumination, or use of tones over a short period of time may cause the
watch to enter a power recovery mode, which is indicated by a recovery indicator (
R) to flash on the
digital display. The watch will remain in the power recovery mode until battery power recovers.
E-13
•Illumination, tones, and sensor operations are disabled and the hands of the watch stop until battery
power recovers.
•Battery power takes about 15 minutes to recover. The recovery indicator (
R) will stop flashing and
normal watch operation will be restored when battery recovery is complete.
•Frequent flashing of the recovery indicator (
R) indicates that battery power is low. Expose the watch to
light to charge its battery.

the Specifications (page E-106).
E-14
Power Saving
Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area
where it is dark. The table below shows how watch functions are affected by Power Saving.
•There actually are two sleep state levels: “display sleep” and “function sleep”.
•With this watch, the Power Saving function cannot be disabled.
Elapsed Time in Dark Hands and Display Operation
60 to 70 minutes (display sleep) Blank display, second hand
stopped at 12 o’clock.
Except for display and second hand, all
functions enabled.
6 or 7 days (function sleep) Blank display, all hands
stopped at 12 o’clock.
Except for timekeeping, all functions
disabled.
•The watch will not enter a sleep state between 6:00 AM and 9:59 PM. If the watch is already in a sleep
state when 6:00 AM arrives, however, it will remain in the sleep state.
•You will not be able to enter the Compass, Barometer/Thermometer, Altimeter, Stopwatch, or
Countdown Timer Mode while the watch is in a sleep state.
To recover from the sleep state
Move the watch to a well-lit area, press any button, or angle the watch towards your face for reading (page
E-91).
E-15
Radio Controlled Atomic Timekeeping
This watch receives a time calibration signal and updates its time setting accordingly. However, when
using the watch outside of areas covered by time calibration signals, you will have to adjust the settings
manually as required. See “Configuring Current Time and Date Settings Manually” (page E-31) for more
information.
This section explains how the watch updates its time settings when the city code selected as the Home
City is in Japan, North America, Europe, or China, and is one that supports time calibration signal
reception.
If your Home City Code setting is this: The watch can receive the signal from the transmitter
located here:
LONDON (LON), PARIS (PAR), ATHENS (ATH) Anthorn (England), Mainflingen (Germany)
HONG KONG (HKG) Shangqiu City (China)
TOKYO (TYO) Fukushima (Japan), Fukuoka/Saga (Japan)
HONOLULU (HNL), ANCHORAGE (ANC),
LOS ANGELES (LAX), DENVER (DEN), CHICAGO (CHI),
NEW YORK (NYC)
Fort Collins, Colorado (United States)
Important!
•The areas covered by HONOLULU (
HNL) and ANCHORAGE ( ANC) are quite far from the calibration
signal transmitters, so certain conditions may cause reception problems.
•When HONG KONG (
HKG) is selected as the Home City, only the time and date are adjusted
according to the time calibration signal. You need to switch manually between standard time and
daylight saving time (DST) if required. See “To configure Home City settings” (page E-28) for
information about how to do this.

•Even when the watch is within range of a transmitter, signal reception may be impossible due to the
effects of geographic contours, structures, weather, the time of year, the time of day, radio interference,
etc. The signal becomes weaker at distances of approximately 500 kilometers, which means that the
influence of the conditions listed above becomes even greater.
•Signal reception may not be possible at the distances noted below during certain times of the year or
day. Radio interference may also cause problems with reception.
Mainflingen (Germany) or Anthorn (England) transmitters: 500 kilometers (310 miles)
Fort Collins (United States) transmitter: 600 miles (1,000 kilometers)

Taking Direction Readings
The Compass Mode uses the watch’s direction sensor to detect magnetic north. The second hand will
indicate magnetic north and the digital display shows one of 16 directions and an angle value.
To take a direction reading
1. Check to make sure the watch is in the Timekeeping Mode or one of
the sensor modes.
• The sensor modes are the Compass Mode, Barometer/Thermometer
Mode, and Altimeter Mode.
2. Place the watch on a flat surface. If you are wearing the watch, make
sure that your wrist is horizontal (in relation to the horizon).
3. Point the 12 o’clock position of the watch in the direction you want to
measure.
4. Press Cto start the direction reading operation, which is indicated by
COMP appearing on the digital display.
• When you press C, the second hand will first point in the direction
of the C(COMP) button. This indicates the Compass Mode. After
that the second hand will point in the direction of magnetic north.
• For information about direction reading results, see “Interpreting
Direction Reading Results” (page E-35).
5. After you are finished taking direction readings, press
Dto return to
the Timekeeping Mode.

Interpreting Direction Reading Results
•When you press C,COMP appears on the digital display to indicate that direction reading has started.
•After about two seconds, the second hand moves to point to magnetic north. The digital display shows
either the angle between magnetic north and the 12 o’clock position of the watch, or one of 16 literal
direction indicators.
•The watch updates the direction reading about once every second for about 20 seconds, and then
stops. The digital display shows - - - and the second hand moves to COMP (located below the C
button) to indicate that direction readings are complete. If your want to continue taking direction
readings, press Cagain.
•Pressing Eat this time switches the digital display between the angle value and a one-, two-, or
three-character literal direction indicators.
•The Auto Light switch is disabled during the 20 seconds that direction readings are being taken.
•The following table shows the meanings of the abbreviations used for the literal direction indicators that
appear on the digital display.
Direction Meaning Direction Meaning Direction Meaning Direction Meaning

northeast NE Northeast ENE East- northeast
EEast ESE East-
southeast SE Southeast SSE South- southeast
SSouth SSW South-
southwest SW Southwest WSW West- southwest
WWest WNW West-
northwest NW Northwest NNW North- northwest
•The margin of error for the angle value and the direction indicator is ±11 degrees while the watch is
horizontal (in relation to the horizon). If the indicated direction is northwest (
NW) and 315 degrees, for
example, the actual direction can be anywhere from 304 to 326 degrees.
E-36
•If the second hand is indicating 12 o’clock (north), the digital display will show an upwards pointing
white on black arrow.
• The small scale in the center of the watch face is a direction scale (page E-34). You can use the
direction scale to get an idea of how many degrees the 12 o
’ clock position of the watch is (clockwise)
from the northerly indication of the second hand. The direction scale is marked in 10-degree increments.
Some watch models may not have a direction scale.
•Note that taking a measurement while the watch is not horizontal (in relation to the horizon) can result in
large measurement error.
• You can calibrate the bearing sensor if you suspect the direction reading is incorrect.
•Any ongoing direction measurement operation is paused temporarily while the watch is performing an
alert operation (daily alarm, Hourly Time Signal, countdown timer alarm) or while illumination is turned
on (by pressing L). The measurement operation resumes for its remaining duration after the operation
that caused it to pause is finished.
•For precautions that should be observed when using the Compass Mode, see “Compass Precautions”
(page E-43).
Calibrating the Bearing Sensor
You should calibrate the bearing sensor whenever you feel that the direction readings being produced by
the watch are off. There are three different calibration methods available: magnetic declination correction,
bidirectional calibration, and northerly calibration.
•Magnetic Declination Correction
With magnetic declination correction, you input a magnetic declination angle (difference between
magnetic north and true north), which allows the watch to indicate true north. You can perform this
procedure when the magnetic declination angle is indicated on the map you are using. Note that you can
input the declination angle in whole degree units only, so you may need to round off the value specified
on the map. If your map indicates the declination angle as 7.4°, you should input 7°. In the case of 7.6°
input 8°, for 7.5° you can input 7° or 8°.
E-37
•Bidirectional Calibration and Northerly Calibration
Bidirectional calibration and northerly calibration calibrate the accuracy of the bearing sensor in relation
to magnetic north. Use bidirectional calibration when you want to take readings within an area exposed
to magnetic force. This type of calibration should be used if the watch becomes magnetized for any
reason. With northerly calibration, you “teach” the watch which way is north (which you have to determine
with another compass or some other means).
Important!
The more correctly you perform bidirectional calibration, the better the accuracy of the bearing sensor
readouts. You should perform bidirectional calibration whenever you change environments where you
use the bearing sensor, and whenever you feel that the bearing sensor is producing incorrect readings.
To perform magnetic declination correction
1. In the Compass Mode, hold down Euntil each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Use A(East) and C(West) to change the settings.
• The following explains magnetic declination angle direction settings.
0°: No magnetic declination correction performed. The magnetic
declination angle with this setting is 0°.
E: When magnetic north is to the east (east declination)
W: When magnetic north is to the west (west declination)
• You can select a value within the range of W 90° to E 90° with these
settings.

time. This will cause OFF to appear on the digital display. After about one second, the magnetic
declination will change to 0 degrees.
• The illustration on page E-37 shows declination angle direction value and the angle value you should
select when a map shows a magnetic declination of “West 1°”.
3. When the setting is the way you want, press Eto exit the setting screen.
Precautions about bidirectional calibration
•You can use any two opposing directions for bidirectional calibration. You must, however, make sure
that they are 180 degrees opposite each other. Remember that if you perform the procedure
incorrectly, you will get wrong bearing sensor readings.
•Do not move the watch while calibration of either direction is in progress.
•You should perform bidirectional calibration in an environment that is the same as that where you plan
to be taking direction readings. If you plan to take direction readings in an open field, for example,
calibrate in an open field.
To perform bidirectional calibration
1. In the Compass Mode, hold down Euntil each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Press Dto display the bidirectional calibration screen.
• At this time, the digital display will show -1- to indicate that the watch
is ready to calibrate the first direction.
E-39
3. Place the watch on a level surface facing any direction you want, and press Cto calibrate the first
direction.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show -2-. This means that the watch is ready for calibration of
the second direction.
• Calibration takes about 13 seconds. Do not move the watch while calibration is being performed.
4. Rotate the watch 180 degrees.
5. Press Cagain to calibrate the second direction.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show OK and then change to the Compass Mode screen (- - -).
To perform northerly calibration
Important!
If you want to perform both northerly and bidirectional calibration, perform bidirectional calibration first,
and then perform northerly calibration. This is necessary because bidirectional calibration cancels any
existing northerly calibration setting.
1. In the Compass Mode, hold down Euntil each of the following steps
occurs.
• Hold SET appears on the digital display. ➝ Magnetic declination
settings flash.
• This is the setting screen.
2. Press Dtwice to display the northerly calibration screen.
• At this time, -n- (north) appears on the digital display.
3. Place the watch on a level surface, and position it so that its 12 o’clock position points north (as
measured with another compass).

4. Press Cto start the calibration operation.
• - - - is shown on the digital display while calibration is being performed. When calibration is
successful, the digital display will show OK and then change to the Compass Mode screen (- - -).
Using the Compass While Mountain Climbing or Hiking
This section provides two practical applications for using the watch’s built-in compass.
•Setting a map and finding your current location
Having an idea of your current location is important when mountain climbing or hiking. To do this, you
need to “set the map”, which means to align the map so the directions indicated on it are aligned with
the actual directions of your location. Basically what you are doing is aligning north on the map with
north as indicated by the watch.
•Finding the bearing to an objective
To set a map and find your current location
1. With the watch on your wrist, position it so the face is horizontal.
2. While in the Timekeeping Mode or in any of the sensor modes, press Cto take a compass reading.
• The reading result will appear on the digital display after about two seconds, and the second hand
will point to north.
E-41
3. Rotate the map without moving the watch so the northerly direction
indicated on the map matches north as indicated by the watch.
• If the watch is configured to indicate magnetic north, align the
map’s magnetic north with the watch indication. If the watch has
been configured with a declination to correct to true north, align
the map’s true north with the watch indication. For details about
magnetic declination correction, see “Calibrating the Bearing
Sensor” (page E-36).
• This will position the map in accordance with your current location.
4. Determine your location as you check the geographic contours around
you.

information about how to perform the above step.
2. Set the map so the direction you want to travel on the map is pointed
straight in front of you.
3. With the watch on your wrist, position it so the face is horizontal.
4. While in the Timekeeping Mode or in any of the sensor modes, press
Cto take a compass reading.
• The reading result will appear on the digital display after about two
seconds, and the second hand will point to north.
5. Still holding the map in front of you, turn your body until north as
indicated by the watch and the northerly direction on the map are
aligned.
• This will position the map in accordance with your current location,
so the bearing to your objective is straight ahead of you.

Compass Precautions
This watch features a built-in magnetic bearing sensor that detects terrestrial magnetism. This means that
north indicated by this watch is magnetic north, which is somewhat different from true polar north. The
magnetic north pole is located in northern Canada, while the magnetic South Pole is in southern Australia.
Note that the difference between magnetic north and true north as measured with all magnetic compasses
tends to be greater as one gets closer to either of the magnetic poles. You should also remember that
some maps indicate true north (instead of magnetic north), and so you should make allowances when
using such maps with this watch.
Location
•Taking a direction reading when you are near a source of strong magnetism can cause large errors in
readings. Because of this, you should avoid taking direction readings while in the vicinity of the
following types of objects: permanent magnets (magnetic necklaces, etc.), concentrations of metal
(metal doors, lockers, etc.), high tension wires, aerial wires, household appliances (TVs, personal
computers, washing machines, freezers, etc.).
•Accurate direction readings are impossible while in a train, boat, air plane, etc.
•Accurate readings are also impossible indoors, especially inside ferroconcrete structures. This is
because the metal framework of such structures picks up magnetism from appliances, etc.
Storage
•The precision of the bearing sensor may deteriorate if the watch becomes magnetized. Because of
this, you should store the watch away from magnets or any other sources of strong magnetism,
including: permanent magnets (magnetic necklaces, etc.) and household appliances (TVs, personal
computers, washing machines, freezers, etc.).
•Whenever you suspect that the watch may have become magnetized, perform the procedure under “To
perform bidirectional calibration” (page E-38).
E-44

measured temperature is within the allowable range.
Display Units
You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured
barometric pressure, and Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature
value. See “To specify temperature, barometric pressure, and altitude units” (page E-69).
E-46
Barometric Pressure Graph
Barometric pressure indicates changes in the atmosphere. By monitoring
these changes you can predict the weather with reasonable accuracy.
This watch takes barometric pressure measurements automatically every
two hours (at the 30th minute of every even numbered hour).
Measurement results are used as the data to create the barometric
pressure graph that appears on the digital display, and the second hand
indicates the barometric pressure differential.
Reading the Barometric Pressure Graph
The barometric pressure graph shows readings of previous measurements for up to 16 hours.
•The horizontal axis of the graph represents time, with each dot
standing for two hours. The rightmost dot represents the most recent
reading.
•The vertical axis of the graph represents barometric pressure, with
each dot standing for the relative difference between its reading and
that of the dots next to it. Each dot represents 1 hPa.
The following shows how to interpret the data that appears on the barometric pressure graph.
A rising graph generally means improving weather.

Pressure Sensor and Temperature Sensor Calibration
The pressure sensor and temperature sensor built into the watch are calibrated at the factory and normally
require no further adjustment. If you notice serious errors in the pressure readings and temperature
readings produced by the watch, you can calibrate a sensor to the reading of another device to correct the
errors.
Important!
•Incorrectly calibrating the pressure sensor can result in incorrect readings. Before changing the
calibration value, make sure the readings you are using are reliable and accurate.
•Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
–
Compare the readings produced by the watch with those of another reliable and accurate thermometer.
– If adjustment is required, remove the watch from your wrist and wait for 20 or 30 minutes to give the
temperature of the watch time to stabilize.
E-50
To calibrate the pressure sensor and the temperature sensor
1. Take a reading with another measurement device to determine the
exact current barometric pressure or temperature.
2. With the watch in the Timekeeping Mode or in any of the sensor
modes, press Bto enter the Barometer/Thermometer Mode.
3. Hold down Euntil each of the following steps occurs.
• Hold SET appears on the digital display. ➝ The current temperature

Barometer and Thermometer Precautions
•The pressure sensor built into this watch measures changes in air pressure, which you can then apply
to your own weather predictions. It is not intended for use as a precision instrument in official weather
prediction or reporting applications.
•Sudden temperature changes can affect pressure sensor readings.
•Temperature measurements are affected by your body temperature (while you are wearing the watch),
direct sunlight, and moisture. To achieve a more accurate temperature measurement, remove the
watch from your wrist, place it in a well ventilated location out of direct sunlight, and wipe all moisture
from the case. It takes approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.
E-52
Taking Altitude Readings
The watch displays altitude values based on air pressure readings taken by a built-in pressure sensor.
How the Altimeter Measures Altitude
The altimeter can measure altitude based on its own preset values (initial default method) or using a
reference altitude specified by you.
When you measure altitude based on preset values
Data produced by the watch’s barometric pressure sensor is converted to approximate altitude based on
ISA (International Standard Atmosphere) conversion values stored in watch memory.
When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch uses that value to convert
barometric pressure readings to altitude (page E-62).
•When mountain climbing, you can specify a reference altitude value in
accordance with a marker along the way or altitude information from a
map. After that, the altitude readings produced by the watch will be more
accurate than they would without a reference altitude value.

Reading the Altitude Graph
The altitude graph shows Altimeter Mode auto measurement readings over time.
•The vertical axis of the graph represents altitude, and each dot stands
for 10 meters (40 feet).
•The horizontal axis represents time. For the altitude readings taken
during the first three minutes after you start an altimeter measurement
operation, each dot represents five seconds. After that, each dot
represents two minutes (under initial default settings).
•An out of range reading or a measurement error will cause the column
of dots for that reading to be blank (skipped).
Note
•The measurement range for altitude is –700 to 10,000 meters (–2,300 to 32,800 feet).
•The displayed altitude value changes to - - - - if an altitude reading falls outside the measurement
range. An altitude value will reappear as soon as the altitude reading is within the allowable range.
• Normally, displayed altitude values are based on the watch’s preset conversion values. You also can
specify a reference altitude value, if you want. See “Specifying a Reference Altitude Value” (page E-61).
•You can change the unit for displayed altitude values to either meters (m) or feet (ft). See “To specify

Using the Altitude Differential Value
In the Altimeter Mode, the part of the watch’s dial from 11 o’clock to 7
o’clock acts as an altitude differential scale. The second hand points to a
place on the scale that indicates the difference between the altitude at a
start point set by you and the altitude at your current location. The altitude
differential indication is updated each time the watch takes an altitude
reading.
You can configure the watch so each second mark in the altitude
differential scale stands for 5 meters (20 feet) or 50 meters (200 feet).
See “Configuring the Altitude Differential Scale” (page E-58) for
information about how to configure this setting.
•The second hand will point to OVER or UNDER if the altitude
differential is outside the allowable range of the scale.
•The second hand will move to 9 o’clock if a sensor reading could not
be taken for some reason or if the reading is outside the allowable
range.
•See “Using the Altitude Differential Value While Mountain Climbing or

4. While comparing the altitude difference you determined on the map
and the watch’s altitude differential value, advance towards your
destination.
• If the map shows a difference of +80 meters between your current
location and your destination, you will know that you are
approaching your destination when the second hand is pointed
at +80 meters.
Specifying a Reference Altitude Value
The altitude readings produced by this watch are subject to error caused by changes in air pressure.
Because of this, we recommend that you update the reference altitude value whenever one is available
during your climb. After you specify a reference altitude value, the watch adjusts its air-pressure-to-altitude
conversion calculation accordingly.

occurs.
• Hold SET appears on the digital display. ➝ Hold SET disappears.
2. Press A(+) or C(–) to change the current reference altitude value
by 5 meters (or 20 feet).
• Specify a reference altitude value based on accurate altitude
information about your current location from a map, etc.
• You can set the reference altitude value within the range of –10,000
to 10,000 meters (–32,800 to 32,800 feet).
• Pressing
Aand Cat the same time returns to OFF (no reference
altitude value), so the watch performs air pressure to altitude
conversions based on preset data only.
3. Press Eto exit the setting screen.
Types of Altitude Data
The watch can maintain two types of altitude data in its memory: manual save records, and auto save
values (low altitude, high altitude, cumulative ascent, cumulative descent).
•Use the Data Recall Mode to view data stored in memory. See “Viewing Altitude Records” (page E-72)
for details.
E-63
Manual Save Records
Any time you perform the procedure below in the Altimeter Mode, the watch will create and store a record
with the currently displayed altitude reading, along with the date and time the reading was taken. There is
enough memory to store up to 14 manual save records, which are numbered from REC01 through
REC14.
To create a manual save record
1. In the Altimeter Mode, check to make sure that an altitude reading is
on the digital display.
• If an altitude reading is not displayed, press
Ato take one. See “To
take an altimeter reading” (page E-53) for details.
2. Hold down Auntil Hold REC appears on the digital display and then
changes to REC.
• This will save the currently displayed altitude reading in a manual
save record, along with the measurement time and date.
• The watch will return to the Altimeter Mode screen automatically after
the save operation is complete.
• There is enough memory to store up to 14 manual save records. If
there are already 14 manual save records in memory, the above
operation will cause the oldest record to be deleted automatically
to make room for the new one.

Operation Guide 5114 5214
E-64
Auto Save Values
While the altitude auto measurement method is being used (page E-55), the watch automatically stores
high altitude (
HI), low altitude ( LO), cumulative ascent ( ASC), and cumulative descent ( DSC) values.
•These values are checked and updated automatically by the watch as altitude auto measurements are
taken.
How high altitude and low altitude values are updated
While the watch is in the Altimeter Mode, altitude readings are taken automatically at the interval specified
by the altitude auto measurement method (page E-55). With each reading, the watch compares the
current reading against the HI and LO values. It will replace the HI value if the current reading is greater
than HI, or the LO value if the current reading is less than LO.
How Cumulative Ascent/Descent Values Are Updated

r
r(500 m) = 820 m
•Entering the Altimeter Mode starts a new altitude auto measurement session, but it does not reset the
current ASC and DSC values or change them in any way. This means that the starting ASC and DSC
values for a new Altimeter Mode auto measurement session are the values that currently are in memory.
Each time you complete an Altimeter Mode auto measurement session by returning to the Timekeeping
Mode, the cumulative ascent value of the current session (920 meters in the above example) is added
to the session’s starting ASC value. Also, the cumulative descent value of the current auto
measurement session (–820 meters in the above example) is added to the session’s starting DSC
value.
•Note that any change in elevation when ascending that is less than 15 meters (49 feet) is not added to
the cumulative ascent value for the current Altimeter Mode auto measurement session. Also, any
change in elevation when descending that is less than –15 meters (–49 feet) is not added to the
cumulative descent value for the current Altimeter Mode auto measurement session.
Note
•The high altitude, low altitude, cumulative ascent, and cumulative descent values are retained in
memory when you exit the Altimeter Mode. To clear values, perform the procedure under “To delete a
single altitude record” (page E-74) or “To delete all altitude records” (page E-74).
E-66
How does the altimeter work?
Generally, air pressure and temperature decrease as altitude increases. This watch bases its altitude
measurements on International Standard Atmosphere (ISA) values stipulated by the International Civil
Aviation Organization (ICAO). These values define relationships between altitude, air pressure, and
temperature.

•Note that the following conditions will prevent you from obtaining accurate readings:
When air pressure fluctuates because of changes in the weather
Extreme temperature changes
When the watch itself is subjected to strong impact
There are two standard methods of expressing altitude: Absolute altitude and relative altitude. Absolute
altitude expresses an absolute height above sea level. Relative altitude expresses the difference between
the height of two different places.

Altimeter Precautions
•This watch estimates altitude based on air pressure. This means that altitude readings for the same
location may vary if air pressure changes.
•The semiconductor pressure sensor used by the watch for altitude measurements is also affected by
temperature. When taking altitude measurements, do not subject the watch to temperature changes.
•Do not rely upon this watch for altitude measurements or perform button operations while sky diving,
hang gliding, or paragliding, while riding a gyrocopter, glider, or any other aircraft, or while engaging in
any other activity where there is the chance of sudden altitude changes.
•Do not use this watch for measuring altitude in applications that demand professional or industrial level
precision.
•Remember that the air inside of a commercial aircraft is pressurized. Because of this, the readings
produced by this watch will not match the altitude readings announced or indicated the flight crew.
E-69
Specifying Temperature, Barometric Pressure, and Altitude Units
Use the procedure below to specify the temperature, barometric pressure, and altitude units to be used in
the Barometer/Thermometer Mode and the Altimeter Mode.
Important!
When TOKYO (
TYO) is selected as the Home City, the altitude unit is set
automatically to meters (
m), the barometric pressure unit to hectopascals
(hPa), and the temperature unit to Celsius (
°C). These settings cannot
be changed.
To specify temperature, barometric pressure, and altitude units
1. In the Timekeeping Mode, hold down Euntil each of the following
steps occurs.
• Hold SET appears on the digital display. ➝ HT fl a s h e s . ➝ Second
hand points to the current Home City code.
2. Use Dto cycle through the settings on the digital display until the unit
setting screen is shown.
• See step 3 under “To change the current time and date settings
manually” (page E-31) for information about how to scroll through
setting screens.

4. After the settings are the way you want, press Eto exit the setting screen.
E-71
Precautions Concerning Simultaneous Measurement of Altitude and Temperature
Though you can perform altitude and temperature measurements at the same time, you should remember
that each of these measurements requires different conditions for best results. With temperature
measurement, it is best to remove the watch from your wrist in order to eliminate the effects of body heat.
In the case of altitude measurement, on the other hand, it is better to leave the watch on your wrist,
because doing so keeps the watch at a constant temperature, which contributes to more accurate altitude
measurements.
•To give altitude measurement priority, leave the watch on your wrist or in any other location where the
temperature of the watch is kept constant.
•To give temperature measurement priority, remove the watch from your wrist and allow it to hang freely
from your bag or in another location where it is not exposed to direct sunlight. Note that removing the
watch from your wrist can affect pressure sensor readings momentarily.
