ALL RESET AND ZERO POSITIONING
OF ALTITUDE INDICATORS
After a complete discharge of energy and subsequent full
recharge or a malfunction is noted it is necessary to perform
an ALL RESET and ZERO POSITIONING of the altimeter
hands. Following the ALL RESET and ZERO POSITIONING
procedure, the time and calendar must be set.
Rotate the crown (4:00 position) counterclockwise to
unlock the crown from the case.
Pull the crown (4:00 position) out two ‘clicks’. The
altimeter 1,000 ft hand will make a full rotation and
altimeter 10,000 ft hand (9:00 sub dial) will rotate to
its zero position set in memory.
If needed, rotate the crown (4:00 position) so that the
hour and minute hands are not obstructing your view
of the 12:00 position.
Simultaneously press and hold the upper left (A) and
lower left (B) buttons for four seconds, then release.
All three altimeter indicator hands will rotate slightly
indicating a successful all reset.
The altimeter 25 ft hand will move to show a
clear view of the 12:00 position and the altimeter
1,000 ft hand will move slightly indicating it is
ready for zero positioning.
Press and release the upper left button (A) to
move altimeter 1,000 ft hand to the 12:00 position.
NOTE: Pressing and holding the upper left button
(A) will rapidly advance the hand.
Press and release the lower left button (B). The
altimeter 25 ft hand will move to the 12:00 position and
the altimeter 1,000 ft hand will move to provide a clear
view of the 12:00 position. The altimeter 25 ft hand will
move slightly indicating it is ready for zero positioning.
Press and release the upper left button (A) to move
the altimeter 25 ft hand to the 12:00 position.
NOTE: Pressing and holding the upper left button
(A) will rapidly advance the hand.

TO SET THE TIME AND CALENDAR
NOTE: The calendar feature is based on a 31 day month and
must be manually adjusted for months shorter than 31 days.
NOTE: Do not adjust the calendar when the time shown
is between 10:00 PM to 12:00 AM. The calendar gearing
is engaging and manual adjustment may result
in damaging sensitive components.
Rotate the crown (4:00 position) counterclockwise to
unlock the crown from the case.
When the second hand reaches the 12:00 position,
pull the crown (4:00 position) out two ‘clicks’. The
altimeter 1,000 ft hand will make a full rotation and
altimeter 10,000 ft hand (9:00 sub dial) will rotate to
its zero position set in memory.
Rotate the crown (4:00 position) counterclockwise
until you see the date start to change.
Using the time shown as night time reference, continue
rotating the crown (4:00 position) counterclockwise to
set the current time. Setting in this manner will ensure
the correct ‘AM’ or ‘PM’ time is set.
Push the crown (4:00 position) in one ‘click’.
Rotate the crown (4:00 position) clockwise to set the
current date.
For most accurate setting, in accordance with a time

While applying gentle pressure toward the case,
rotate the crown clockwise to lock it into the case.
TO CALIBRATE THE ALTIMETER
NOTE: Altimeter accuracy is affected by weather,
location, temperature, etc. For accurate altimeter
measurement, you must calibrate it for each use. You
may find your current altitude on certain maps, the
internet or other measurement instruments.
Press and release the lower left button (B). The altimeter
25 ft hand will move back and forth slightly and the
altimeter 10,000 ft hand will rotate to the 6:00 position.
After a brief period of atmospheric pressure
measurement, the altimeter hands will rotate
to reflect the current measured altitude.
If altitude indication is incorrect and for more
accurate altitude measurement, you must calibrate
the altimeter to your current location.
Press and hold the lower left button (B) for
approximately three seconds, then release.
The 10,000 ft hand will rotate to ‘+’ indication.
If your current altitude is lower than shown, press
and release the lower left button (B) to change to the
‘-’ indication. If your current altitude is higher than
shown, press and release the lower left button (B) to
change to the ‘+’ indication.
Press and release the upper left button (A) to rotate
the altimeter 25 ft and 1,000 ft hands. The 25 ft
hand should be set to the nearest 25 ft increment
indication. Ex: Current altitude is 89 ft. Position the
altimeter 25 ft hand to indicate ‘100’.
If you need to clear calibration, simultaneously press
and release both the upper left (A) and lower left (B)
buttons. Return to the fourth step.
Press and hold the lower left button (B) for
approximately three seconds, then release.
This completes altimeter calibration.
Press and release the lower left button (B) to exit
the altimeter function.
TO USE THE ALTIMETER

instruction booklet for complete information.
NOTE: To ensure there is sufficient power for altimeter
and compass functions, be sure the power reserve
indicator is at level 2 or higher.
NOTE: Altitude cannot be measured while in a
pressurized aircraft.
NOTE: Atmospheric pressure measurements take place
continuously during the first five minutes of altimeter
operation. After five minutes, atmospheric pressure
measurement is taken once every three minutes.
Press and release the lower left button (B). The altimeter
25 ft hand will move back and forth slightly and the
altimeter 10,000 ft hand will rotate to the 6:00 position.
After a brief period of atmospheric pressure
measurement, the altimeter hands will rotate to
reflect the current measured altitude measurement.
During altimeter operation, you may engage the
compass feature for approximately 30 seconds. Be
sure you have calibrated the compass to ensure
accurate indication.
With the watch in a flat and level position, press and
release the upper left button (A) to start the compass

Press and release the lower left button (B) to stop
the altimeter function. The altimeter 25 ft and
1,000 ft hands will return to the 12:00 position.
The altimeter 10,000 ft hand will rotate to reflect the
current power reserve level. NOTE: The altimeter
function will stop automatically after 12 hours.
TO USE THE COMPASS
NOTE: The compass function indicates magnetic north,
not true north. To determine true north, the declination
must be set as described in the full instruction manual.
NOTE: The compass must be calibrated prior to use to
ensure accurate indication. Refer to the full instruction
booklet for compass calibration procedures.
NOTE: Areas that may emit strong magnetic fields such
as high tension lines, airports, vehicles, or electronic
equipment such as a cell phone or computer, the compass
function may not correctly indicate magnetic north.
NOTE: During compass operation, be sure to keep the
watch as still as possible and in a ‘flat’ (level) position.
With the watch in a flat (level) position, press and
release the upper left button (A). The compass hand
will rotate to show the approximate magnetic north
direction. You may now determine approximate
compass directions. NOTE: Compass functions will
stop automatically after 30 seconds.
Unscrew the scale rotation crown (2:00 position).
Rotate the crown so that the north indication of the
scale lines up with the compass hand.
Press and release the upper left button (A) to stop the
compass function. Using gentle pressure towards the
