Notes on calibrating the Altimeter and Barometer
The watch relies on a sensitive electronic sensor to
measure the air pressure and temperature. This sensor
must be calibrated periodically to maintain the high degree
of accuracy you expect from the watch.
What is calibration?
“Calibration” is simply a technique to improve the accuracy of the pressure/temperature sensor, primarily by compensating for local temperature and weather effects. The
watch employs two related methods of calibration, using
either sea level pressure or the local altitude as a reference, depending on the watch mode used for calibration.
How often should I calibrate?
Timex recommends that you calibrate the sensor prior to
any activity where you will be using the altimeter feature
Weather Forecasting
The watch can predict the weather for the upcoming 4 - 6
hour period based on the air pressure trend information for
the previous twelve hours. The weather forecast is indicated
at the top of the watch display by a series of symbols.
Generally, if the air pressure is rising, the weather situation is
considered to be improving and is indicated by the presence
of the sun symbol. If the air pressure trend is falling, then the
weather situation is worsening and is indicated by showing
the clouds and/or precipitation symbols.
The weather forecast is always visible in TIME and BARO
modes and visible in ALTI mode when no altitude changes
are detected.

reference source available.
For example, if you are standing at a trail head and know
the correct altitude, then the most accurate calibration will
be obtained by calibrating within ALTI mode (since it relies
on altitude as the reference). However, if you don’t know
your altitude, you can find out the current sea level pressure (published online or in a newspaper) and calibrate the
sensor within BARO mode. For example, the U.S. weather
service publishes the sea-level pressure for all of its
stations at http://www.weather.gov
Temperature Accuracy
When worn on your wrist, the thermometer reading is
affected by body heat and may report a temperature
different from the actual air temperature by 10 degrees or
more. Long periods of exposure to direct sunlight may also
affect the accuracy. Try wearing the watch outside your
and then again whenever you experience significant
changes in altitude or temperature during your activity.
If you are not using the altimeter feature, then daily
calibration will maintain the accuracy of the barometer
and weather forecasting feature.
Whenever possible, the sensor should be calibrated soon
after you experience significant temperature changes.
Do I need to calibrate both the Barometer and the
Altimeter?
No. BARO mode calibrates the sensor based upon the sea
level air pressure, while ALTI allows you to calibrate the
sensor by telling the watch about your current altitude.
Calibration performed in either mode will calibrate the
sensor for all modes. For the best accuracy, we recommend that you choose only one calibration method each
time you calibrate the sensor, based on the most accurate

(in the lower display line) and the weather forecast
(at the top of the display).
Setting Time of Day
Refer to section entitled “Setting Operation” on page 11 to
understand how the buttons function during setting.
You may set the following values for Time of Day:
Hour, Minute, Seconds, Year, Month, Date, Date Format,
Time Format, Hourly Chime.
jacket (in cold weather) or clipping it to your belt or pack
(ideally in an area not constantly exposed to the sun) to
improve the accuracy of the temperature readings during
outdoor activities. For the most accurate readings, remove
the watch from your wrist and put in shade for at least
several minutes.
The watch can measure water temperature also, if
submerged. Be sure to select temperature display before
placing the watch in water, as buttons should not be
pressed with the watch underwater.
TIME - Time of Day Mode
In this mode you may view the current time and date in
either of two time zones and switch between them. The
time can be displayed in 12- or 24-hour format. In addition
to the time of day, the watch can display the current
barometer (air pressure) value or the current temperature
1918

Using the Dual Time Zone feature
The watch can keep track of the time for two zones
(T1 and T2). By default, T1 is the “primary” time zone (the
one that you can see) and T2 is the “secondary” time zone
(the one you can’t see). The indicator for the primary time
zone is shown in the lower left of the display.
Viewing the secondary time zone
You may temporarily view (or “peek” at) the secondary
time zone by briefly pressing and holding the STOP/RESET
button. While you are “peeking” at the secondary time
zone, its indicator (T1 or T2) will flash in the lower
left-hand side of the display. When you release the
STOP/RESET button, the watch will display the time for
the primary time zone once again.
NOTES:
• Be sure you have selected the intended time zone
(T1 or T2) before you begin setting; you cannot switch
zones while setting (see “Using the Dual Time Zone
feature” on pg 21).
• When setting the hour value, be sure to set to the
correct part of the day (AM or PM) (12-hour format only).
• The seconds’ value can only be set to “0” and cannot
be set individually for each time zone.
• The day of the week is automatically calculated based
on the date.
• The watch will automatically adjust for leap years up
to 2049.
• When the hourly chime is enabled, a confirmation
beep will also be generated whenever a key is
pressed.

BARO - Barometer Mode
Want a better understanding of the forces that influence
the weather? This is the mode to do just that – here you
can view the current air pressure (local and sea level),
monitor the current temperature and study the changes in
air pressure over time, presented in a graphical format.
Finally, the weather forecast for the next 4 - 6 hours is
shown at the top of the display.
Switching time zones
If you wish to switch to the secondary time zone, simply
continue holding the STOP/RESET button until the time
zone indicator (T1 or T2) stops flashing (this takes about
three seconds). This will be your new primary time zone
until you switch it back.
Viewing Temperature and Air Pressure Data
While in TIME mode, press and release the START/SPLIT
button to view the following information on the lower line
of the watch display:
• The current air pressure
• The current temperature
• The month and date
2322

When viewing the Time of Day, Sea Level Pressure and
Temperature group, press STOP/RESET to toggle temperature display units (°F or °C).
NOTE: Unit selection made for temperature and barometric
pressure in BARO mode applies to all modes in the watch.
For example, if you select “°C” for the temperature display
in BARO mode, it will also appear in °C in Time of Day and
Altimeter modes.
Calibrating the Barometer
Calibration in BARO mode allows you to synchronize the
weather forecasting feature with the current weather
situation and also to calibrate the pressure sensor for
improved accuracy.
