Using Reference Altitude Values
To minimize the chance of reading error, you should update the reference altitude value before setting off
on a trek or any other activity where you plan to take altitude readings. During a trek, keep checking the
readings produced by the watch against altitude information provided by markers and other information,
and update the reference altitude value as required.
• Reading error can be caused by changes in barometric pressure, atmospheric conditions, and
elevation.
• Before performing the procedure below, look up the altitude of your current location on a map, the
Internet, etc.

Advanced Altimeter Mode Operations
Use the information in this section to obtain more accurate altimeter readings, especially while mountain
climbing or trekking.
Using an Altitude Differential Value
If you specify a reference altitude, the second hand of the watch will
Altitude differential Altitude differential
indicate the difference between the current altitude and the reference
altitude. The displayed altitude differential value is updated each time the
watch obtains a new altitude reading value.
• Depending on the currently selected display range, the allowable
range for the altitude differential value is 100 meters to –100 meters
(100 meters = 328 feet), or 1,000 meters to –1,000 meters (1,000
meters = 3,280 feet).
• If a reading value is outside the allowable range either

• The second hand will move to 9 o'clock if a sensor reading could not
be taken for some reason or if the reading is outside the allowable
range.
• See "Using the Altitude Differential Value While Mountain Climbing or
Hiking" (page E-59) for some real-life examples of how to use this
feature.

To use the altitude differential value
1. In the Altimeter Mode, check to make sure that an altitude reading is
on the display.
Destination Destination
If an altitude reading is not displayed, press A to take one. See "To

take altitude readings" (page E-55) for details.
2. Use the contour lines on your map to determine the difference in
altitude between your current location and your destination.
3. In the Altimeter Mode, hold down D for at least two seconds to specify
your current location as the altitude differential start point.

• DIFF RESET and then RESET will appear. The watch will take an

altitude reading, and the second hand will indicate the altitude
differential. ±0 (±0 meters) will be displayed as the altitude
differential at the reference point.

• If the map shows that the difference in altitude between your
location and your destination is +80 meters for example, you know
you will be nearing your destination when the displayed altitude
differential value shows +80 meters.

• The second hand will move to 9 o'clock if a reading is outside the altimeter measurement range (−700
to +10,000 meters (–2,300 to 32,800 feet)), or if a reading error occurs.
Types of Altitude Data
Your watch can record two types of altitude data in its memory: manually saved data and auto save
values.
• Use the Data Recall Mode to view data stored in memory. See "Viewing Altitude Records" (page E-83)
for details.

To specify a reference altitude value
• You can set the reference altitude value within the range of –3,000 to 10,000 meters (–9,840 to

Using the Altitude Differential Value While Mountain Climbing or Hiking
After you specify the altitude differential start point while mountain climbing or hiking, you can easily
measure the change in the altitude between that point and other points along the way.
The altitude differential with the reference location is indicated by the second hand (altitude differential
indicator) as shown in the illustration below.

Manually Saved Records
Any time you perform the procedure below in the Altimeter Mode, the watch will create and store a record
with the currently displayed altitude reading, along with the date and time the reading was taken. There is
enough memory to store up to 30 manually saved records, which are numbered from -01- through -30-.
To save a reading manually
1. In the Altimeter Mode, pull out the crown.
• This will cause the current altitude reading value to fl ash on the
digital display.
• The timekeeping (hour, minute, second) hands will move to 2
o'clock.
2. Rotate the crown to change the altitude value in one-meter (fi ve-foot)
increments.
• You can also use HS1 high-speed movement (page E-5) to change
this setting.
• Change the reference altitude value to an accurate altitude reading
that you get from a map or other source.
You can use the procedure below to select either ±100 meters or ±1,000
meters as the altitude differential measurement range.

To specify the altitude differential measurement range
1. In the Altimeter Mode, pull out the crown.
• This will cause the current altitude reading value to appear.
• The timekeeping (hour, minute, second) hands will move to 2

2. Press B twice.
• This will cause DIFF to appear on the digital display, along with the
fl ashing current altitude differential measurement range setting.
3. Rotate the crown to select either 100 meters (100m) or 1,000 meters
(1000m) as the altitude differential measurement range.

on the display.
If an altitude reading is not displayed, press A to take one. See "To

2. Hold down A until REC fl ashes and then stops fl ashing.
• This will save the currently displayed altitude reading in a manually
saved record, along with the time and date of the reading.
• The watch will return to the Altimeter Mode screen automatically
after the save operation is complete.
• There is enough memory to store up to 30 manually saved records.
If there are already 30 manually saved records in memory, the
above operation will cause the oldest record to be deleted
automatically to make room for the new one.
