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.

Increase of 3 hPa/mb
Decrease of 3 hPa/mb
Within ± 3 hPa/mb
• 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.
