NOTES ON USING THE WATCH
MODE CHANGE
●If the stopwatch is not reset to “00” and button A is pressed to change the mode from the
STOPWATCH, the TIMER mode appears, skipping the STROKE mode.
TIME/CALENDAR MODE
●In setting the seconds, when the seconds read any number from “30” to “59” and button D is pressed,
one minute is added and the seconds are reset to “00”.
●Note on unusual display:
While setting the time/calendar, all the segments of the display will light up if both buttons C and D
are pressed at the same time. This is not a malfunction. Press any one of the buttons to return to the
TIME/CALENDAR mode, and then set the time/calendar again.
STOPWATCH MODE
●The lap number counts up to “99”. After that, it is displayed in 2
digits such as “00” for 100, “01” for 101, and so on.
●Even if the digits are reset to “00” in the stopwatch measurement,
stored data is not erased and can be recalled unless a new
measurement is started.
CHRO

ILLUMINATING LIGHT (Electroluminescent panel)
●The electroluminescent panel loses its luminance as the battery voltage decreases. Also, its
luminance level decreases gradually with use.
●When the illuminating light becomes dim, replace the battery with a new one. If the illuminating light
remains dim after the battery is replaced, have the electroluminescent panel replaced with a new one
by the retailer from whom the watch was purchased, or an AUTHORIZED SEIKO DEALER. It will be
replaced at cost.
●While the illuminating light is used, the watch gives out a slight noise. However, this is not a
malfunction.
BATTERY CHANGE
The miniature battery which powers your watch should last approximately
2 years. However, because the battery is inserted at the factory to check
the function and performance of the watch, its actual life once in your
possession may be less than the specified period. When the battery expires,
be sure to replace it as soon as possible to prevent any malfunction. For
battery replacement, we recommend that you contact an AUTHORIZED
SEIKO DEALER and request SEIKO CR2025 battery.
2
Years
* The battery life may be less than 2 years if the alarm is used for more than 20 seconds
a day and/or the illuminating light more than 3 times a day.
●Battery life indicator
When all the digits start flashing, have the battery replaced with a new one as soon
as possible.

18
English
●Necessary procedure after battery change
After the battery is replaced with a new one, or if an abnormal display (broken digits,
etc.) appears, follow the procedure below to reset the IC.
Press and hold buttons A, B, C and D at the same time for 2 to
3 seconds. The display shown at right appears.
* Before using the watch, set the time/calendar and alarm.
●Never short-circuit, heat or otherwise tamper with the battery, and never
expose it to fire. The battery may burst, become very hot or catch fire.
●The battery is not rechargeable. Never attempt to recharge it, as this may cause
battery leakage or damage to the battery.
CAUTION
●Do not remove the battery from the watch.
●If it is necessary to take out the battery, keep it out of the reach of children. If
a child swallows it, consult a doctor immediately.

• If the watch becomes wet, have it
checked by an AUTHORIZED

Your watch works with stable
accuracy within a temperature

Temperatures over 50°C (122°F) or below
–10°C (+14°F) may cause a slight time loss
or gain or battery leakage or shorten the
battery life.
However, the above conditions will be
corrected when the watch returns to normal
temperature.
●Non-water resistant
●Water resistant 5/10/15/20 bar
• Do not operate the buttons when
the watch is wet or in water.
If used in sea water, rinse the
watch in fresh water and dry it
completely.
• When taking a shower with a water
resistant 5 bar watch, or taking a
bath with a water resistant 10, 15
or 20 bar watch, be sure to observe the
following:
* Do not operate the buttons when the watch
is wet with soapy water or shampoo.
* If the watch is left in warm water, a slight
time loss or gain may be caused. This
condition, however, will be corrected when
the watch returns to normal temperature.
* Pressure in bar is a test pressure and
should not be considered as
corresponding to actual diving depth
since swimming movement tends to
increase the pressure at a given
depth. Care should also be taken on
diving into water.
** We recommend that you wear a
SEIKO Diver’s Watch for scuba
diving.
