To set the digital time and date

1. Hold down A while in the Timekeeping Mode until the

seconds digits start to flash on the display. The seconds

flash because they are selected .

2. Press C to change the selection in the following

3. While the seconds digits are selected (flashing), press D to reset the seconds to

"00". If you press D while the seconds count is in the range of 30 to 59, the

seconds are reset to "00" and 1 is added to the minutes. If the seconds count is in

the range of 00 to 29, the minutes count is unchanged.

4. While any other digits (besides seconds) are selected (flashing), press D to

increase the number or B to decrease it. Holding down either button changes the

current selection at high speed.

While the 12/24-hour setting is selected, press D or B to switch between the two

formats.

5. After you set the time, format, and date, press A to return to the Timekeeping

Mode.

• If you do not operate any button for a few minutes while a selection is flashing,

the flashing stops and the watch goes back to the Timekeeping Mode

automatically.

• The day of the week is automatically set in accordance with the date.

• The date can be set within the range of January 1, 1990 to December 31, 2029.

To set the analog time

1. Pull the crown out to stop the seconds hand. If you plan to restart analog

timekeeping on some time signal (from the radio or television), pull the crown out

when the seconds hand is at the 12 o'clock position.

2. Set the hands by turning the crown.

3. Push the crown back in to restart timekeeping.

• Analog time is kept by a mechanical timepiece. Because of this, the seconds

hand may not start to move exactly when you push the crown back in.

About the Barometric Activity Indicator

This watch is equipped with an atmospheric pressure

monitor that takes atmospheric readings. Regardless of

the mode the watch is in, the monitor measures the

atmospheric pressure every three hours (starting from

midnight). Two readings are taken and their average is

applied as the measured value.

Barometric activity

indicator

The direction of the barometric activity indicator is determined using the last two

readings taken by the atmospheric pressure monitor. The last two readings are

compared, and the barometric activity indicator indicates their difference as shown in

the following table.

• This indicator appears on the display in the Timekeeping Mode.

• Some countries refer to the barometric pressure unit hecto-pascal (hPa) as millibars

(mb). It really makes no difference, because 1 hPa = 1 mb. In this manual, we use

hPa/mb or hPa (mb).

GENERAL GUIDE

Altimeter Mode

Alarm Mode

A built-in altimeter uses a pressure sensor to detect the current air pressure, which is

then used to estimate the current altitude in accordance with ISA (International

Standard Atmosphere) values for altitude and air pressure. The readout from the

pressure sensor can be switched between meters (m) and feet (ft.).

• If you do not press any button for one hour in the Altimeter Mode, the display returns

to the Timekeeping Mode automatically.

About Altimeter Mode measurements

The Altimeter Mode automatically measures your current altitude. As soon as you

enter the Altimeter Mode, measurements are taken every three seconds for the first

five minutes. After that, measurements are taken every minute.

Important!

• This watch estimates altitude based on air pressure. This means that altitude

readings for the same location may vary if air pressure changes.

• Sudden changes in the weather make it impossible to produce accurate altitude readings.

• Do not use this watch while participating in sports where there are sudden altitude

changes. Also, do not use this watch for applications that demand professional or

industrial level precision. This watch should not be used while engaging in the

following activities: sky diving, hang gliding, paragliding, gyrocopter riding, glider

riding, etc.

• In order to avoid measurement problems caused by differences in the watch's

temperature, be sure to wear the watch so that it comes into direct contact with your

skin.

Application

Measurement of altitudes during hiking or mountain climbing.

Reading the Altimeter Mode display

Mode indicator

• While an altitude measurement is in progress, the unit of measurement (M or F)

flashes on the display.

• The display shows the message "FULL" if a measured value falls outside the

measuring range. The normal display returns as soon as the pressure falls within the

allowable range again.

• Hold down D to show the altitude differential display. If a measurement is in

progress, the current altitude measurement is shown. If no measurement is in

progress, the display shows "– – – –".

Calibrating the Altimeter

The altitude measurements produced on this watch may be affected by atmospheric

pressure. Because of this, we suggest that you calibrate the altimeter using

information available from a map or other source.
