ALTIMETER SCALE

(units)
NOTE: Watch is shipped with guard around crown. Remove guard and push crown in to start.
Altimeter must be calibrated before using to ensure accuracy and avoid improper altitude
reading. See Altimeter Calibration section for complete details.
Pull crown to MIDDLE position and turn until correct date appears. After setting date, pull
crown all the way out and turn until correct time is shown. Ensure correct AM/PM setting by
verifying that date changes at midnight, not noon. Push crown in when done. Adjust date after
months with fewer than 31 days.
INDICATOR HAND (4TH CENTER HAND) ADJUSTMENT
Pull crown all the way out. The upper and lower retrograde hands reset to the start of their
scales automatically. Indicator hand (4th center hand) should point to 12 o'clock. If it does not,
press either A and/or B button to move hand until it points to 12 o'clock. A and B buttons
move hand counterclockwise and clockwise, respectively. Hold button to move hand fast. Push
crown in when done.
Before use, the altimeter must be calibrated.
Since an altimeter uses pressure to determine the altitude and pressure varies from place to
place, it is important to set the altimeter to a known reference altitude value, or to a standard
reference altitude of a given place. Sudden changes in pressure due to changes in weather
can cause your altimeter reading to be off by +-100m (328 ft), even if your location has not
changed. Recalibrate to a known altitude when drastic pressure changes occur.
To calibrate the altimeter:
1. Pull the crown to its middle position and wait for the indicator hands to stop moving.
2. If the altimeter was OFF at the moment of crown pulling, the lower retrograde hand will
point to the unit selected the last time the altimeter was used, otherwise the lower retro-
grade hand points to the current selected unit in altitude display. The 4th center hand and
upper retrograde hand should point to the current altitude.
3. Press A or B to move the 4th center hand counterclockwise or clockwise, respectively, until
it points to the desired calibration altitude. Holding A or B will move the center hand more
rapidly. The upper retrograde hand moves relative to the altitude value displayed by the 4th
center hand.
4. Push crown in when done.
To change the unit from METERS to FEET or FEET to METERS, press C. If button C is not
released within one second, changes made in calibration are discarded and the current
altitude is displayed.
To turn the altimeter on, press C. The lower retrograde hand points to METERS. Using the mark-
ings on the top ring, the 4th center hand shows the current altitude's hundreds and tens value
with divisions every ten METERS/FEET. The upper retrograde hand shows the current altitude's
thousands value with divisions every one thousand METERS/FEET.
To change the unit from METERS to FEET, press C a second time. To change the unit from FEET
to METERS, press C twice (altimeter is turned off first then turned back on with the unit in
METERS).
To turn the altimeter off with the current unit set to FEET, press C. To turn the altimeter off
with the unit set to METERS, press C twice (lower hand goes to FEET first before going to the
OFF position).
The watch will automatically turn the altimeter off after 60 minutes from activation.
Example: Altitude=2310 m
To view the maximum recorded altitude, press A. The lower retrograde hand shows the unit of
measure that the maximum altitude was recorded in if the altimeter was OFF at the moment
of button press, otherwise it will show the maximum altitude using the current selected unit.
The 4th center hand shows the maximum altitude's hundreds and tens value with divisions
every ten METERS/FEET. The upper retrograde hand shows the maximum altitude's thousands
value with divisions every one thousand METERS/FEET.
The maximum recorded altitude is displayed for ten seconds. To extend the display duration for
another ten seconds, press A before the previous ten second duration expires.
To change the unit from METERS to FEET or FEET to METERS, press C.
To view the minimum recorded altitude, press B. The lower retrograde hand shows the unit of
measure that the minimum altitude was recorded in if the altimeter was OFF at the moment of
button press, otherwise it will show the minimum altitude using the current selected unit. The
4th center hand shows the minimum altitude's hundreds and tens value with divisions every
ten METERS/FEET. The upper retrograde hand shows the minimum altitude's thousands value
with divisions every one thousand METERS/FEET.
The minimum recorded altitude is displayed for ten seconds. To extend the display duration for
another ten seconds, press B before the previous ten second duration expires To change the
unit from METERS to FEET or FEET to METERS, press C.
