Note

• The barometric pressure graph is not displayed while the barometric pressure change indicator is

displayed.

• While the watch is in the Barometer Mode, the watch will update the display barometric pressure value

at regular intervals (every ﬁ ve seconds for the ﬁ rst three minutes and then every two minutes for the

remainder of the hour). Since the barometric pressure graph show automatic readings taken every two

hours, the graph is updated only at two-hour intervals.

• Large changes in barometric pressure may cause past readings to run off the

top or bottom of the graph display area.

• The following conditions cause the barometric pressure reading to be

skipped, with the corresponding point on the barometric pressure graph

being left blank.

– Barometric reading that is out of range (260 hPa to 1,100 hPa or 7.65 inHg to 32.45 inHg)

– Sensor malfunction

Barometric Pressure Change Indications

Whenever your watch detects a signiﬁ cant change in air pressure readings (due to sudden ascent or

descent, or to the passage of a low pressure or high pressure area), it beeps to let you know. Also, an

arrow ﬂ ashes on the digital display and the small hand points to the arrow mark. All of this is intended to

let you know what a signiﬁ cant pressure change has occurred so you can take any action that might be

required.

The barometric pressure change indicator is displayed in the Barometer Mode and while the barometric

pressure graph is displayed in the Timekeeping Mode (page E-33).

• For example, you could enable the barometric pressure change indicator after arriving at a lodge or

campsite. Then, before setting out the following day, you could check for changes in barometric

pressure, which will give you some idea of upcoming weather conditions.

Reading the Barometric Pressure Change Indicator

Small Hand and Digital Display Meaning

Sudden fall in pressure.

Sudden rise in pressure.

Sustained rise in pressure, changing to a fall.

Sustained fall in pressure, changing to a rise.

• The barometric pressure change indicator is not displayed if there has been no noteworthy change in

barometric pressure. In such a case, the small hand is at 6 o’clock.

E-50

Important!

• To ensure proper results, take barometric readings under conditions where the altitude remains

constant.

• A change in altitude causes a change in barometric pressure. This means that correct barometric

pressure readings are not possible while you are changing altitudes. To avoid possible confusion, it is

probably best to disable the barometric pressure change indicator while you are on the move during

your climb.

To enable or disable the barometric pressure change indicator

In the Barometer Mode or the Timekeeping Mode, hold down

for at least two seconds until

INFO

appears on the digital display, and the current indicator setting toggles between

(enabled) and

OFF

(disabled).

• The small hand acts as a barometric pressure change indicator while ON, and a Tide Graph while

OFF.

• BARO is shown on the digital display while the indicator is enabled.

• Note that barometric pressure change indicator display will turn off automatically 24 hours after

you turn it on or battery power goes low.

• Enabling or disabling the Barometric Pressure Change Indicator in the Barometer Mode will also

toggle the second hand function between Barometric Pressure Differential Pointer (Barometric

Pressure Change Indicator ON) and current second count indication (Barometric Pressure

Change Indicator OFF) (page E-45). After selecting the Barometric Pressure Change Indicator

setting you want, use

to select the second hand function setting you want.

• Note that time calibration signal reception and power saving (page E-19) are disabled while

barometric pressure change indicator display is enabled.

• Note that barometric pressure change indicator display cannot be enabled while the watch’s

battery is low.

E-51

Pressure Sensor Calibration

The pressure 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 produced by the watch, you can calibrate

the sensor to correct the errors.

Important!

• Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before

performing the calibration procedure, compare the readings produced by the watch with those of

another reliable and accurate barometer.

To calibrate the pressure sensor

1. Take a reading with another measurement device to determine the

exact current barometric pressure.

2. Use

to enter the Barometer Mode (

BARO

), as shown on page

E-31.

3. Pull out the crown. This will cause the current barometric pressure

reading value to ﬂ ash on the digital display.

• The timekeeping (hour, minute, second) hands will move to 2

o’clock.

4. Rotate the crown to adjust the barometric pressure value.

• You can also use HS1 high-speed movement (page E-6) to change

this setting.

• The calibration unit is 1 hPa (0.05 inHg).

• To return the setting to

OFF

(uncalibrated), press

and

at the

same time.

5. After you complete calibration, push the crown back in.

E-52

Barometer 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 ofﬁ cial weather

prediction or reporting applications.

• Extreme temperature changes can affect pressure sensor readings. Because of this, there may be

some error in the readings produced by the watch.

E-53

Taking Direction Readings

You can use the Digital Compass Mode to determine the direction of north, and to check your bearing to a

destination.

• For information about what you can do to improve digital compass reading accuracy, see “Calibrating

the Bearing Sensor” (page E-56) and “Digital Compass Precautions” (page E-60).

To take a direction reading

1. Place the watch on a ﬂ at surface. If you are wearing the watch, make sure that your wrist is horizontal

(in relation to the horizon).

2. Point the 12 o’clock position of the watch in the direction whose reading you want to take.

3. In the Timekeeping Mode or any sensor mode, press

a number of times until

COMP

(Digital

Compass Mode) appears on the digital display.

• In a non-sensor mode, hold down

for about two seconds to enter the Timekeeping Mode. Next,

perform the above step.

• After you enter the Digital Compass Mode (COMP), the watch will start taking bearing readings.

• Starting a digital compass operation will cause the second hand to move momentarily to the

12 o’clock position. Following the digital compass operation, the second hand will point in the

direction of magnetic north. The bearing and direction angle will appear on the digital display.

Note

• After the initial reading is displayed, the watch will continue to take readings and display results

about every second for about the next 60 seconds.

• Pressing

, or rotating the crown while a reading operation is in progress will extend the

operation for approximately 60 seconds from point the button was pressed or the crown was

rotated.

• The watch will return to the Timekeeping Mode about 60 seconds after the direction reading

operation is complete.

• Pressing

while a reading operation is in progress will stop the operation and enter the

Timekeeping Mode.

E-55

Important!

• If the second hand does not point exactly at 12 o’clock after you perform step 3 above, perform the

operation under “Hand Home Position Adjustment” (page E-39) to adjust it.

• If the digital display contents start to ﬂ ash after you perform a reading operation, it means that

abnormal magnetism has been detected. Move away from any potential source of strong magnetism

and try taking a reading again. If the problem occurs when you try again, continue to keep away from

the source of strong magnetism, perform bidirectional calibration, and then try taking a reading again.

For more information, refer to “To perform bidirectional calibration” (page E-57) and “Location” (page

E-60).

Digital Compass Readings

• After the ﬁ rst reading is obtained, the watch will continue to take digital compass readings automatically

each second for up to 60 seconds. After that, the reading operation will stop automatically.

• The auto light switch is disabled during the 60 seconds that digital compass readings are being taken.

• The margin of error for the angle value and the direction indicator is ±10 degrees while the watch is

horizontal (in relation to the horizon). If the indicated direction is northwest (

) and 315 degrees, for

example, the actual direction can be anywhere from 305 to 325 degrees.

• Note that taking a direction reading while the watch is not horizontal (in relation to the horizon) can

result in large direction reading error.

•

You can calibrate the bearing sensor if you suspect the direction reading is incorrect.

• Any ongoing direction reading 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

). The direction reading operation resumes for its remaining duration after the operation

that caused it to pause is ﬁ nished.

• See “Digital Compass Precautions” (page E-60) for important information about taking direction readings.
