Moving the Hands for Easy Viewing of the Digital Dials
You can use the procedure below to move the analog hands in order to view the dial and the digital
display better.
Note
• The analog hands will not move while battery power is low.
To shift the hands and view digital info
While holding down
L
, press
B
.
• This will cause the timekeeping (hours, minutes, seconds) hands to move to 2 o’clock.
• To return the hands to their normal positions, press
A
,
B
, or
C
.
E-41
Note
• The hands will also return to their normal positions if you do not perform any operation for about 10
seconds.
• If the hands have moved to 2 o’clock because you pulled out the crown,* they will return to their normal
positions when you push the crown back in.
In this case, the hands will return to normal timekeeping when you push the crown back in.
* The hands will not move to 2 o’clock if you pull out the crown while confi guring the city code setting
(pages E-34, E-77) or the summer time setting (pages E-34, E-77), or while manually confi guring
time and date settings (page E-36).
Auto Hand Shift
If the hour hand and/or minute hand is over the digital display when a displayed barometric pressure,
altitude, or temperature reading is updated, the hand(s) will shift automatically (to 4 o’clock or 8 o’clock)
and provide a better view of the information on the display.
The hands will return to their normal position after about three seconds.

Specifying Altitude, Barometric Pressure, and Temperature Units
Use the procedure below to specify the altitude, barometric pressure, and temperature units to be used in
the Altimeter Mode, Barometer Mode and the Thermometer Mode.
Important!
• When
TYO
(Tokyo) is selected as the Home City, the altitude unit is set automatically to meters (
m
), the
barometric pressure unit to hectopascals (
hPa
), and the temperature unit to Celsius (
°C
). These
settings cannot be changed.
To specify altitude, barometric pressure, and temperature units
1. Make sure the watch is in the mode for the type of unit you want to
specify (Altimeter, Barometer, or Thermometer Mode).
• For information about changing modes, see “Selecting a Mode”
(page E-30).
2. Pull out the crown.
• The timekeeping (hour, minute, second) hands will move to
2 o’clock.
3. Press
B
as many times as necessary until
UNIT
appear on the digital
display.
• For altitude, press
B
three times. For barometric pressure and
temperature, press
B
once.
4. Rotate the crown to change the unit setting.
5. After the settings are the way you want, push the crown back in.

Taking Barometric Pressure Readings
This watch uses a pressure sensor to measure air pressure (barometric pressure).
To take barometric pressure readings
In the Timekeeping Mode or any sensor mode, press
A
a number of
times until
BARO
(Barometer Mode) appears on the digital display.
• In a non-sensor mode, hold down
B
for about two seconds to enter
the Timekeeping Mode. Next, perform the above step.
• About one second after entering the Barometer Mode (
BARO
), the fi rst
barometric pressure reading will be displayed.
• Readings are continuously taken for about one hour: every fi ve
seconds for the fi rst three minutes and then every two minutes for the
remainder of the hour.
• Pressing
C
or
L
, or rotating the crown while a reading operation is in
progress will extend the operation for approximately one hour from
point the button was pressed or the crown was rotated.
• The watch will return to the Timekeeping Mode after the reading
operation is complete (about one hour).
• Pressing
B
while a reading operation is in progress will stop the
operation and enter the Timekeeping Mode.

Note
• When you enter the Barometer Mode, the second hand may indicate seconds (of the current time) or
the barometric pressure differential (page E-45). The initial second hand function will be the same as
what was selected the last time you took a barometric pressure reading. To toggle between the two
second hand functions (indicating seconds or indicating the barometric pressure differential) press
C
.
Barometric Pressure
• Barometric pressure is displayed in units of 1 hPa (or 0.05 inHg).
•
The displayed barometric pressure value changes to
- - -
if a measured barometric pressure falls outside
the range of 260 hPa to 1,100 hPa (7.65 inHg to 32.45 inHg). The barometric pressure value will reappear
as soon as the measured barometric pressure is within the allowable range.
Display Units
You can select either hectopascals (hPa) or inchesHg (inHg) as the display unit for the measured
barometric pressure. See “To specify altitude, barometric pressure, and temperature units” (page E-42).
E-45
Checking Barometric Pressure Changes and Trends
Your watch provides the three methods below for checking barometric pressure changes and trends.
• Checking the latest change in barometric pressure (Barometric pressure differential pointer described
below)
• Checking barometric pressure changes for the past 20 hours (Barometric Pressure Graph, page E-47)
• Checking for signifi cant barometric pressure changes (Barometric Pressure Change Indicator, page
E-49)
Barometric Pressure Differential Pointer
Your watch automatically takes barometric pressure measurements every two hours (at the 30 minute
mark of each even numbered hour), regardless of the mode it is in.
The second hand of the watch indicates the difference between the current barometric reading and
previous automatic reading, within the range of ±10hPa (1hPa unit). This keeps you informed about
current barometric pressure changes in your area.
To show and hide barometric pressure differential
1. In the Timekeeping Mode or any sensor mode, press
A
a number of times until
BARO
(Barometer
Mode) appears on the digital display.
• In a non-sensor mode, hold down
B
for about two seconds to enter the Timekeeping Mode. Next,
perform the above step.
2. Press
C
.
Note
• Press
C
to toggle the second hand between its two functions (indicating seconds or indicating the
barometric pressure differential).
E-46
Reading Barometric Pressure Differential Pointer
Pressure differential is indicated in the
range of ±10 hPa (0.3 inHg), in 1 hPa (0.03
inHg) units.
• The nearby screen shot, for example,
shows what the second hand would
indicate when the calculated pressure
differential is approximately – 5 hPa
(approximately – 0.15 inHg).
• The second hand will point to
+ OVER
or
– UNDER
if the barometric pressure
differential is outside the allowable range
of the scale.
• 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.
• Barometric pressure is calculated and
displayed using hPa as the standard.
The barometric pressure differential also
can be read in inHg units as shown in
the illustration (1 hPa
=
0.03 inHg).

Barometric Pressure Graph
Your watch automatically takes barometric pressure measurements every
two hours (at the 30 minute mark of each even numbered hour), regardless of
the mode it is in.
While the watch is in the Barometer Mode or Timekeeping Mode, the digital
display shows a graph of pressure change for the past 20 hours (10
readings). By monitoring these changes you can predict the weather with
reasonable accuracy.
• To display the barometric pressure graph in the Timekeeping Mode, press
C
a number of times to cycle through digital display screens until it
appears (page E-33).
Reading the Barometric Pressure Graph
The barometric pressure graph shows a chronological history of pressure readings.
• The vertical axis of the graph represents barometric pressure, with each
dot standing for the relative difference between its reading and that of the
dots next to it. Each dot represents 1 hPa.
• The latest automatic reading is indicated by the rightmost segment in the
graph.
The following shows how to interpret the data that appears on the barometric pressure graph.
Rising barometric pressure indicates that upcoming weather will improve.
Falling barometric pressure indicates that upcoming weather will deteriorate.
