BATTERY LIFE INDICATOR

• When the second digits start flashing in the TIME/CALENDAR mode, replace the battery with a new one as soon as possible. Otherwise, the watch will stop operating in a couple of days. We suggest that you have the battery replaced by an AUTHORIZED SEIKO DEALER.

*Even after the battery life indicator appears, time accuracy is not affected.

BATTERY CHANGE

The miniature battery which powers your watch should last approximately 3 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 SR1130W battery.

* The battery life may be less than 3 years if:

• the alarm is used for longer than 20 seconds a day,
• the stopwatch is used for longer than 3 minutes a day,
• the confirmation sound is used more than 10 times a day, and/or
• the timer is used more than once a day.

NECESSARY PROCEDURES AFTER CHANGING THE BATTERY

* After the battery is replaced with a new one, or in case an abnormal display (broken numerals or letters etc.) appear, follow the procedures below to reset the IC.

* All digital indicators are reset to show " 1", " SUN" and "12:00 00" in the TIME / CALENDAR mode.

Press and hold the four buttons for 2 to 3 seconds at the same time.

All digital indicators disappear at once and the display shown at left appears when the buttons are released.

Set the digital time/calendar and analogue time.
(See "TIME/CALENDAR SETTING")

• 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.
• Never short-circuit, tamper with or heat 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.

TO PRESERVE THE QUALITY OF YOUR WATCH

WATER RESISTANCE

Indication on case back	Degree of water resistance*	Condition of use	Accidental contact with water such as rain and splashes	Swimming, yachting and taking a shower	Taking a bath and shallow diving	Scuba diving** and saturation diving
No indication	Non-water resistant		No	No	No	No
WATER RESISTANT	3 bar		Yes	No	No	No
WATER RESISTANT 5 BAR	5 bar		Yes	Yes	No	No
WATER RESISTANT 10/15/20 BAR	10/15/20 bar		Yes	Yes	Yes	No

• Non-water resistant
  
  • If the watch becomes wet, have it checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER.

• 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.

TEMPERATURES

Your watch works with stable accuracy within a temperature range of 5°C and 35°C (41°F and 95°F).
Temperatures over 60°C (140°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.

SHOCKS & VIBRATION

Be careful not to drop your watch or hit it against hard surfaces.

MAGNETISM

The analogue unit of your watch will be adversely affected by strong magnetism, though the digital unit will not be affected. Keep the watch away from close contact with magnetic objects.

CHEMICALS

Be careful not to expose the watch to solvents, mercury, cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged.

CARE OF CASE AND BRACELET

To prevent possible rusting of the case and bracelet, wipe them periodically with a soft dry cloth.

PERIODIC CHECK

It is recommended that the watch be checked once every 2 to 3 years. Have your watch checked by an AUTHORIZED SEIKO DEALER or SERVICE CENTER to ensure that the case, buttons, gasket and crystal seal remain intact.

PRECAUTION REGARDING CASE BACK PROTECTIVE FILM

If your watch has a protective film and/or a sticker on the case back, be sure to peel them off before using your watch.

STATIC ELECTRICITY

The IC (Integrated Circuit) used in your watch will be affected by static electricity which may disturb the display. Keep the watch away from close contact with objects such as TV screens which emit strong static electricity.

LIQUID CRYSTAL PANEL

The normal life expectancy for a liquid crystal panel is approximately 7 years. After that it may decrease in contrast, becoming difficult to read. Please contact your AUTHORIZED SEIKO DEALER or SERVICE CENTER if you wish to have a new panel fitted (guaranteed one year).
