Ex.: 20 and 7/10 seconds

Ex.: when measurement is stopped or split time is measured
Second hand 1/10 second hand***

1/10 second hand*

Second hand * 1/10 second hand moves from 0 to 9 (minute markers) repeatedly.
Minute hand *** When the measurement is stopped or split time is measured, 1/10 second hand indicates the 1/10 seconds measured. When the measurement is restarted or split time is released, it returns to 0 position.
**1/10 second hand stays at 0 position while the stopwatch is counting.
STOPWATCH OPERATION English
q Before using the stopwatch, be sure to reset the hands to 0 position.

1 Standard measurement

2 Accumulated elapsed time measurement

RESTART

* Restart and stop of stopwatch can be repeated by pressing Button B.

3 Split time measurement

STOP SPLIT RESET RELEASE * Measurement and release of split time can be repeated by pressing Button A.
TACHYMETER (for models with tachymeter scale on the dial)
To measure the hourly average speed of a vehicle

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

Second hand: 40 seconds

Tachymeter scale: 90
90 (tachymeter scale figure) x 1 (km or mile) = 90 km/h or mph
* Tachymeter scale can be used only when the time required is less than 60 seconds.
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or miles and Second hand indicates 90 on tachymeter scale:
90 (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph
90 (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph
To measure the hourly rate of operation
Use the stopwatch to measure the time required to complete 1 job. Tachymeter scale indicated by Second hand gives the average number of jobs accomplished per hour.

Second hand: 20 seconds

Tachymeter scale: 180
180 (tachymeter scale figure) x 1 job = 180 jobs/hour
Ex. 2: If 15 jobs are completed in 20 seconds:
180 (tachymeter scale figure) x 15 jobs = 2700 jobs/hour
NECESSARY PROCEDURE AFTER BATTERY CHANGE
q When the battery is replaced, the information stored in the IC does not correspond with the time and date actually displayed. Before using the watch, therefore, be sure to reset the hands and date, following the procedure below.
Pull out. Press and hold at the same time for 2 seconds.
* A beep sounds when the buttons are released, and the hands start to show demonstration movement.

Press to stop the hands.

Press to reset the selected hand to the 12 oclock position or set the date to 1. (See *2 on page 22) Push back in to normal position.
* After resetting the hands and date as explained above, set the time and calendar. (See TIME SETTING and CALENDAR)
NOTES ON OPERATING THE WATCH
*1 When a hand is selected, it will move back and forth and return to where it was. When the date is selected, it will advance one day and return to the current date. *2 The hand(s)/date move(s) quickly if the corresponding button is kept pressed for 2 seconds. *3 As Minute hand moves, Hour hand also moves correspondingly. *4 When setting Hour hand, check that AM/PM is correctly set.
Press Button A to turn Hour hand past the 12 oclock 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. While the date is changing, Hour hand stops on the 12 oclock position even if Button A is kept pressed.

*5 The alarm time can be set with the CROWN both at the normal position and at the extended position. *6 Alarm test: With the CROWN at ALM.ON, press and hold Buttons A and B at the same time. *7 Remarks on timer operation: In TIMER mode, Hour hand stops at the 12 oclock position. With each press of the buttons, a beep sounds for confirmation. Even if the mode is changed from TIMER to another while the timer is counting down, it continues counting. If the timer is stopped, however, the hands will be reset to 0 position by changing the mode. 22
*8 Remarks on stopwatch operation: With each press of the buttons, a beep sounds for confirmation. Even if the mode is changed from STOPWATCH to another while the stopwatch is measuring, it continues counting. If the split time is measured, however, it will be released and counting will be continued by changing the mode.
66 Demonstration movement of hands 66 If Buttons A and B are pressed at the same time for 2 seconds, Hour and Minute hands turn counterclockwise and clockwise, respectively, and Second hand moves back and forth at the 12 oclock position.
* To stop the demonstration, press Button A or B. * If the watch is left untouched with the hands showing the demonstration movement, they will automatically return to indicate the current time in about 2 minutes.

MODE INDICATOR at TIME

BATTERY LIFE INDICATOR

q The battery needs to be replaced when you see the Second hand moving at two-second intervals instead of normal one-second intervals. * The watch will, however, remain accurate while Second hand is moving at two-second intervals.

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.
* The battery life may be less than 2 years if: the alarm is used more than once a day, the timer is used for more than 5 minutes a day, and/or the stopwatch is used for more than 5 minutes a day.

WARNING

q Do not remove the battery from the watch. q 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. q 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.

CAUTION

q The battery is not rechargeable. Never attempt to recharge it, as this may cause battery leakage or damage to the battery.

This condition, however, will be corrected when the watch returns to normal temperature.
Your watch works with stable accuracy within a temperature range of 5C and 35 C (41F and 95F).
Temperatures over 60C (140F) or below 10C (+14F) 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.

s SHOCKS & VIBRATION

Be careful not to drop your watch or hit it against hard surfaces.
s CARE OF CASE AND BRACELET
To prevent possible rusting of the case and bracelet, wipe them periodically with a soft dry cloth.
