3. When stopwatch has been reset and Button A is pressed before the hands reach "0" position, stopwatch still starts counting when Button A is pressed.

TACHYMETER

(for models with tachymeter scale on the dial)

To measure the hourly average speed of a vehicle

1. Use the stopwatch to determine how many seconds it takes to go 1 km or 1 mile.
2. Tachymeter scale indicated by STOPWATCH second hand gives the average speed per hour.

To measure the hourly rate of operation

1. Use the stopwatch to measure the time required to complete 1 job.
2. Tachymeter scale indicated by STOPWATCH second hand gives the average number of jobs accomplished per hour.

ADJUSTING THE HAND POSITION

• If STOPWATCH hands will not return to the 12 o'clock position when the stopwatch is reset or when the battery is replaced with a new one, follow the procedure below.

Pull out to second click.

Press repeatedly to reset STOPWATCH minute hand to the 12 o'clock position.

Press repeatedly to reset STOPWATCH second hand to the 12 o'clock position.

NOTE
Before using the watch again, be sure to adjust the position of STOPWATCH hands and set the main time and alarm.

BATTERY LIFE INDICATOR

• When the battery nears its end, the small second hand moves at two-second intervals instead of normal one-second intervals to indicate that the battery needs to be replaced with a new one.
  * If the alarm is used while the second hand is moving at two-second intervals, the watch may stop operating. Therefore, if you see the second hand moving at two-second intervals, replace the battery with a new one as soon as possible.

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 SR927W battery.

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.

TO PRESERVE THE QUALITY OF YOUR WATCH

WATER RESISTANCE

• 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
  • Before using in water, be sure the crowns are pushed in completely.
    
  • Do not operate the crowns and 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 the water resistant 5 bar watch, or taking a bath with the water resistant 10, 15 or 20 bar watch, be sure to observe the following:
    * Do not operate the crowns or push 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.

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) may cause battery leakage or shorten the battery life.

Do not leave your watch in very low temperatures below –10°C (+14°F) for a long time since the cold may cause a slight time loss or gain.

However, the above conditions will be corrected when the watch returns to normal temperature.

SHOCKS & VIBRATION

Light activities will not affect your watch, but be careful not to drop your watch or hit it against hard surfaces, as this may cause damage.

MAGNETISM

Your watch will be adversely affected by strong magnetism. Keep it away from close contact with magnetic objects.

CARE OF CASE AND BRACELET

To prevent possible rusting of the case and bracelet caused by dust, moisture and perspiration, 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, crowns, buttons, gasket and crystal seal remain intact.

CHEMICALS

Be careful not to expose the watch to solvents (e.g., alcohol and gasoline), mercury (i.e., from a broken thermometer), cosmetic spray, detergents, adhesives or paints. Otherwise, the case, bracelet, etc. may become discolored, deteriorated or damaged.

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. Otherwise, perspiration getting in under them may rust the case back.
