u Some models may have a screw-lock mechanism that can securely lock the
crown by a screw when not being operated.
u Locking the crown will help prevent operational errors and enhance the
water resistant quality of the watch.

DISPLAY AND BUTTONS
Some models may have a screw-lock-type crown. If your watch does, refer to the
“SCREW- LOCK-TYPE CROWN” section on the next page. Simplified illustrations may be used in the following sections of this manual.
Keep the crown securely locked unless you need to operate it.
[How to unlock it]
Turn the crown counterclockwise.
The crown is unlocked and can then be operated.
[How to lock it]
Once you have finished operating the crown, turn it
clockwise while gently pressing it in toward the watch body
until it stops.
•
When locking the crown, turn it slowly with care, ensuring that the
screw is properly engaged. If there is any resistance, unscrew it and
try again. Be careful not to forcibly push it in, as doing so may damage
the screw hole in the case.
7
Once the crown is pulled out to the second click, be sure to check and adjust
1) and 2) at the same time. If needed, 3) should also be adjusted then.
Pull out to the second click when the second hand is at the 12 o'clock
position.

2. The 24-hour hand moves correspondingly with the hour hand.
3. If the alarm has been set and the crown is pulled out to the second click, the ALARM hands will turn
to indicate the current time.
4. It is recommended that the hands be set to the time a few minutes ahead of the current time, taking
into consideration the time required to set the ALARM hands and to adjust the STOPWATCH hand
position if necessary.
5. When setting the hour hand, be sure to check that AM/PM is correctly set. The watch designed so
that the date changes once in 24 hours.
6. When setting the minute hand, first advance it 4 to 5 minutes ahead of the desired time and then
turn it back to the exact minute.

NOTE ON POWER SUPPLY
● When the energy stored in the rechargeable battery is reduced to an extremely
low level, the second hand starts moving at 2-second intervals instead of the
normal 1-second intervals. The watch remains accurate even while the second
hand is moving at 2-second intervals.
● The battery used in this watch is a rechargeable battery, which is different
from ordinary silver oxide batteries. Unlike other disposable batteries such as
dry-cell batteries or button cells, this rechargeable battery can be used over
and over again by repeating the cycles of discharging and recharging.
● The capacit y or recharging ef ficiency of the rechargeable bat ter y may
gradually deteriorate for various reasons such as long-term use or usage
conditions. Worn or contaminated mechanical parts or degraded oils may
also shorten recharging cycles. If the efficiency of the rechargeable battery
decreases, it will be necessary to have the watch repaired.
● When this occurs, recharge the watch as soon as possible by exposing it to light.
Otherwise, the watch may stop operating in a few days. (For recharging the
watch, see “HOW TO CHARGE AND START THE WATCH”)
•
While the second hand is moving at 2-second intervals, the stopwatch cannot be activated.
This is not a malfunction.
•
If the second hand starts to move at 2-second intervals while the stopwatch is operating,
the stopwatch will be automatically stopped and the stopwatch hands will return to the “0”
position.
•
While the second hand is moving at 2-second intervals, the alarm time cannot be set.
•
If the time reaches the alarm time while the second hand is moving at 2-second intervals,
the alarm will not sound, and the alarm will be automatically cancelled.
v TO PREVENT THE ENERGY DEPLETION

When wearing the watch, make sure that the watch is not covered by
clothing.
When the watch is not in use, leave it in a bright place as long as
possible.

ENERGY DEPLETION FOREWARNING FUNCTION
CAUTION
● Do not remove the rechargeable battery yourself. Replacement of the
rechargeable battery requires professional knowledge and skill. Please

HOW TO USE THE TELEMETER
Before beginning, check that the stopwatch has been reset.
l The telemeter can provide a rough indication of the distance to the source of
light and sound.
l The telemeter indicates the distance from your location to an object that emits
both light and sound. For example, it can indicate the distance to the place
where lightning struck by measuring the time elapsed after you see a flash of
lightning until you hear the sound.
l A flash of lightning reaches you almost immediately while the sound travels to
you at a speed of 0.33 km/second. The distance to the source of the light and
sound can be calculated on the basis of this difference.
l The telemeter scale is graduated so that the sound travels at a speed of 1 km in
3 seconds.*

2 When you hear the sound,
(Crash of thunder)
press Button A to stop the
stopwatch.
*Under the condition of temperature of 20° C(68° F)
3 Read the telemeter scale
that the STOPWATCH 1/5second hand points to.
CAUTION
The telemeter provides only a rough indication of the distance to the place
where lightning struck, and therefore, the indication cannot be used as the
guideline to avoid the danger of lightning. It should also be noted that the
speed of the sound differs depending on the temperature of the atmosphere
where it travels.

•
Please note that the STOPWATCH 1/5-second hand moves in 1/5-second increments and does not
always point exactly to the graduations of the telemeter scale. The telemeter scale can be used
only when the measured time is less than 60 seconds.

then reset the time. The watch has been adjusted so that it works accurately when
it is worn on your wrist under a normal temperature range between 5 ºC and 35 ºC.
The watch has been left close to an object
with a strong magnetic field.
Correct this condition by moving and keeping the watch away from the
magnetic source. If this action does not correct the condition, contact the
retailer from whom the watch was purchased.
You have dropped the watch, hit it against a hard
surface or worn it while playing active sports.
The watch was exposed to strong vibrations.
Reset the time. If the watch does not return to its normal accuracy after
resetting the time, contact the retailer from whom the watch was purchased.
