B. Operating Instructions
V: Pressure (altimetry) sensor: Detects the
atmospheric pressure and displays as altimetry
via an IC.
Z: Register-ring: Setting the register-ring allows you
to determine the difference in altitude. If the
indicated altitude value changes at the same
place, this indicates changes in the air pressure.
If the altitude hand shifts to indicate a lower
altitude the air pressure has increased.
C. Setting the Time and Date
[Time Mode]
• The time mode displays both 12-hour and 24-hour time.
• The hour, minute and 24-hour hands indicate the
time even when the watch is in Chronograph Mode.
[Setting the Time
and Date]
1. Setting the time
If your watch is a
type with a screw-
lock crown,
unscrew the
crown.
➀ Pull the crown out two steps. The second hand will
spin rapidly and stop at 0.
➁ Set the hours and minutes to the current time by
turning the crown. Check the 24-hour hand to
confirm whether the hands are set appropriately to
AM or PM.
➂ Push the crown back to its original position. The
watch will then resume with the correct time.
2. Setting the date
➀ Pull the crown out one step.
➁ Set the desired date by turning the crown.
➂ Push the crown back to its original position.
Note: If setting the date between hours of 9.00 PM
and 1:00 AM may result in the date not
changing by the next day.
* If your watch is of a type with a screw-lock crown,
tighten the crown after setting the time and/or date.
D. Altimetry
1. Altimetry
• The altimeter automatically
measures altitude every hour in
Time Mode.
• The altimeter measures and
displays from -300m to 5,000m
in 10m gradation.
• Altitude hand [I] (A) is
synchronized with [II] (B) to
display the current altitude.
Altitude hand [I] (A): Displays the altitude in 10m
gradation.
Altitude hand [II] (B): Displays the altitude in 1,000m
gradation.
Note: The altimeter displays “-300m” for an altitude
less than -300m, and “5,000m” for more than
5,000m.
2. Reading the altimetry displays
(1) Altitude from 0 to 1,000 m
* The figure below shows an altitude of 190 m.
(2) Altitude from 1,000 to 2,000 m
* The figure below shows an altitude of 1,350 m.
(3) Altitude from -300 to 0 m
* The figure below shows an altitude of -100 m.
3. Continuous altimetry
The watch shows continuous changes in altitude once
every 5 seconds for 30 minutes after the starting
measurement for altitudes.
• Measuring the altitudes.
Press button ➁ once in Time Mode. The second
hand changes to operate on an extended 2-second
increment basis. This indicates that the watch is now
in Continuous Altimetry Mode.
Pressing button ➁ once returns the watch to altimeter
mode. Also, the watch will automatically return to
Altimeter Mode 30 minutes after being set to
Continuous Altimetry Mode even if no button is
pressed.
