NOTES ON USING THE WATCH

ADJUSTING THE HAND POSITION
● The STOPWATCH minute hand moves in correspondence with the STOPWATCH second hand.
TIME/CALENDAR SETTING
● Before setting the time, be sure to stop and reset the stopwatch.
● Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, the date may not change properly.
If it is necessary to set the date during that time period, first change the time to any time outside it,
set the date and then reset the correct time.
● When setting the hour hand, check that AM/PM is correctly set. The watch is so designed that the
date changes once in 24 hours.
Turn the hands past the 12 o'clock marker to determine whether the watch is set for the A.M. or P.M.
period. If the date changes, the time is set for the A.M. period. If the date does not change, the
time is set for the P.M. period.
● When setting the minute hand, advance it 4 to 5 minutes ahead of the desired time and then turn it
back to the exact time.
● Do not press any button with the crown at the second click. Otherwise, the STOPWATCH hands
move and resetting them is made necessary.
STOPWATCH
● The STOPWATCH 1/10 second scale and hand differ in design and shape depending on the model.
● Do not pull out the crown while the stopwatch is counting. If it is pulled out, the stopwatch operation
cannot be made.
● When the stopwatch is reset, it takes up to 40 seconds for the STOPWATCH second and minute
hands to return to "0" position.

BATTERY CHANGE

The miniature battery which powers your watch should last approxi-
mately 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 SR920SW battery.
* If the stopwatch is used for more than 60 minutes a day, the battery life may be
less than 2 years.
WARNING
● 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.
CAUTION
● Never short-circuit, heat or otherwise tamper with the battery, and never ex-
pose 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.
