3. Before Using
Before using your watch, check that the functions of
the watch operate properly by following procedure
(0-position check).
1. Press button 
Mto switch the
watch to the 0-position check
mode [0]. The hour hand,
minute hand, 24H hand,
second hand, date and function
hand will advance rapidly to
the 0-position (base position).
Hour, minute and 24H hands .......... 00:00 (24:00)
Second hand ................................... 00 seconds
Date ................................................. 1st
Function hand .................................. 0-position
(12:00 position)
* Perform the “0-Position Correction” procedure when
any hand is not at the 0-position. If this 0-position is
not correct, the hands will not show the correct
position (such as not returning to “00” when
resetting the chronograph).

10. Setting Local Time [L-TM]
The local time function enables the time in a different
time zone to be set separately from the current time.
Local time is set by performing a time difference
correction on 1 hour units based on the current time
(time of the TME mode). The minute and second
hands move in coordination with the current time.


Bor Cdown.
3. Push button 
Min to the normal position.
* The range over which the time difference can be
corrected is from +23 hours to –23 hours based
on the current time (time of the TME mode).
11. What to do when the following occur
[The hands do not indicate the correct positions
in each mode]
• The hand base positions may shift after the watch
has been subjected to a strong impact and so forth.
When this happens, refer to [3. Before Using] and
perform the “0-Position Correction” procedure.
[The watch exhibits an abnormal display or
operation]
• In extremely rare situations, the watch may exhibit
an abnormal display or erroneous operation (such
as the alarm continuing to sound, or the hands
turning continuously) as a result of being subjected
to the effects of static electricity or strong impact
and so forth. When this happens, perform the “All-
Reset” procedure while reffering to the following page.
[After Replacing the Battery]
• After the battery has been replaced, always make
sure to perform the “All-Reset” procedure
described previously. The watch may not run
properly if this operation in not performed.
[All-Reset Procedure]
The all-reset procedure can be
performed in any mode.
1. Pull button 
Mout.
2. Simultaneously press button

A, Band  C. (The confirmation
sounds at this time.)
3. Return button 
Mto the
normal position.
* After performing the all-reset procedure, always
make sure to perform the “0-position correction”
procedure while referring to [3. Before Using]
before resetting the watch to the correct time.
12. Use of the Rotating Bezel
Some watches are not equipped with a bezel,
depending on the model.
1. Tachymeter (non-rotating bezel type)
2. Directional (rotating bezel type)
1. Tachymeter
If your watch is provided with a
tachymeter:
The tachymeter is a feature that
measures the speed of an automobile.
Measuring how many seconds a car
travels over a distance of 1 km
enables the tachymeter scale to show
the approximate average speed per hour during a
journey (if this 1km is covered within a maximum of
60 seconds.)
If the chronograph is started at the beginning of the
distance measurement, and stopped after 1 km, the
average speed per hour can be determined by the
position of the chronograph second hand. If 1km is
covered in 45 seconds, the average speed will be
about 80km/h.

2. Directional rotating bezel
(Northern hemisphere)
If your watch is provided
with a compass bezel:
The compass feature on
this watch is based on the
position of the sun. This
compass should only be
used as an approximate
direction finder. Changes
in laitude and the seasons
may also cause directional
misreadings.
One of the features of this watch is a directional
rotating bezel for use in the Northern Hemisphere.
By aligning the hour hand with the position of the
sun in the sky, the point halfway between this
position and 12 o’clock will be south. Align the “S”
mark on the rotating bezel with this halfway point to
determine all other points of the compass.
13. Precautions and Long Term Use
1. Water resistance
Check the chart to determine the water-resistant
properties of this watch.
* Always set the crown in the normal position.
WATER RESISTANT may sometimes be
abbreviated as WATER RESIST.
2. Avoid extreme temperatures
Avoid leaving your watch in extremely warm or
cold locations for a long period of time.
3. Avoid strong shocks
4. Avoid strong magnetic fields
5. Avoid chemicals and corrosive gases
Avoid wearing this watch in the presence of
chemicals and corrosive gases. If mercury or any
chemical (such as fuel gasoline, thinner, alcohol,
spray liquids of cosmetics or the like), makes
contact with the watch, discolouration, deterioration
or damage to the case, band or other components
may occur.
6. Avoid static electricity
The intergrated circuits used in this watch are
sensitive to static electricity. If exposed to intense
static electricity, the watch’s display may lose it’s
accuracy.
7. Keep the watch clean
It may become difficult to pull the crown out due
to dirt and dust getting caught between the crown
and the case when the watch is worn for long
periods of time. To prevent this from happening,
turn the crown freely back and forth occasionally
while it is in the normal position. Any dirt left on the
case or band may cause skin rash. A watchband
will easily become soiled with dust and
perspiration because it is in direct contact with
the skin. Even a stainless or gold-plated band
may begin to corrode if it has not been cleaned
for a long period of time.
8. Periodic Inspection
Getting your watch checked once every two or
three years is recommended to ensure long use
and trouble-free operation.
9. Be sure to keep the battery away from infants
or small children:
Should accidental ingestion occur, consult a
doctor at once.
