STOPWATCH second hand

STOPWATCH minute hand

• If your watch has a screw down crown, refer to "SCREW DOWN CROWN" section on the next page.
• Simplified illustrations are used in the following sections of this manual.

SCREW DOWN CROWN

• Some models have a screw down crown to prevent accidental operation and help maintain water-resistant quality.
• To use the crown, it is necessary to unlock the crown first before pulling it out, and it is important to securely screw the crown in after each use.

HOW TO OPERATE THE SCREW DOWN CROWN

The crown must be securely locked in the case except when you use it to set the watch.

Turn the crown counterclockwise to unscrew it. The crown is released and projected outward from its original position.

The crown is locked.

Turn the crown clockwise while pressing it to the case until it is screwed all the way in and locked.

• When screwing the crown in, ensure that the crown is correctly aligned and turn it gently. If it is too hard to turn, unscrew it first, and then rewind it. Do not screw it in by force as it may damage the thread of the screw or the case.

TIME ANDCALENDAR SETTING AND STOPWATCH HAND POSITION ADJUSTMENT

• This watch is designed so that the following adjustments are made with the crown at the second click position:

1) time setting
2) stopwatch hand position adjustment

Once the crown is pulled out to the second click, be sure to make both the above adjustments 1) and 2) at the same time.

The date adjustment is done with the crown at first click position.

1) TIME AND CALENDAR SETTING

1. It is necessary to adjust the date at the end of February and 30-day months.
2. Do not set the date between 9:00 p.m. and 1:00 a.m. Otherwise, the date may not change properly.

2) STOPWATCH HAND POSITION ADJUSTMENT

☆ If the STOPWATCH hands are not in the "0" position, follow the procedure below to set them to the "0" position.

HOW TO USE THE STOPWATCH

• The stopwatch features a 40-minute dial with a retrograde minute hand.
• The stopwatch can consecutively measure up to 120 minutes in 1/100-second increments. When the measurement reaches 120 minutes, the stopwatch automatically stops counting.
• Split time measurement is possible.
• After 3 minutes of timing from a start, the STOPWATCH 1/100-second and 1/10-second hands remain pointing to the "0" position until the watch is stopped or split time measurement is made, at such a time, they move to display the measured time. They start to move for a maximum of three minutes after the watch is restarted or the split time display is released.

The time measured is indicated by the four stopwatch hands below.

• Reading the 1/100-second and 1/10-second hands requires extra attention.

• The display illustrated at the left should be read as "19," not "29." When the 1/100-second hand is moving toward larger numbers, the 1/10 second hand comes close to the next marker, which may cause you to wrongly read the hands as "29."

• When the minute counting reaches 40 minutes, the STOPWATCH minute hand immediately returns and continues counting from 41 minutes onward. The minute counting is repeated in the same manner for another rotation, up to 120 minutes, at that time the stopwatch automatically stops.
• The final position of the STOPWATCH minute hand, after completing 120 minutes of counting, is illustrated below.

• Before starting to use the stopwatch again, make sure to reset the stopwatch by pressing Button B.

While the STOPWATCH hands are moving

1. Press Button A to stop the stopwatch.
2. Press Button B to reset the stopwatch.

While the STOPWATCH hands are stopped

(When the stopwatch is stopped)

1. Press Button B to reset the stopwatch.

DEMONSTRATION FUNCTION OF THE STOP-WATCH HAND MOVEMENT

• The demonstration function allows you to view the movement of the four STOPWATCH hands.
  Each of the four STOPWATCH hands demonstrates high-speed movements and when the demonstration is finished, they return to the original position.

- How to view the demonstration

1. Reset the stopwatch.
2. Refer to "HOW TO USE THE STOPWATCH" section of this manual.
3. Press Button B for 2 seconds or longer.

• After approximately 3 seconds, the demonstration finishes, and the stopwatch is reset for the next use.
• If either Button A or B is pressed during a demonstration, the demonstration will be stopped and the stopwatch will be reset.

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 STOPWATCH second hand gives the average speed per hour.

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 2km or miles or shortened to 0.5km or miles and STOPWATCH second hand indicates "90" on tachymeter scale:

90" (tachymeter scale figure) × 2 (km or mile) = 180km / h or mph
90" (tachymeter scale figure) × 0.5 (km or mile) = 45km / 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 STOPWATCH second hand gives the average number of jobs accomplished per hour.

Ex. 1

"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

TELEMETER

(for models with telemeter scale on the dial)

The telemeter can provide a rough indication of the distance to the source of light and sound.
- The telemeter indicates the distance from your location to an object that emits both light and sound. For example, it can indicate the distance to the place where lightning struck by measuring the time elapsed after you see a flash of lightning until you hear the sound.
- A flash of lightning reaches you almost immediately while the sound travels to you at a speed of 0.33km /second. The distance to the source of the light and sound can be calculated on the basis of this difference.
- The telemeter scale is so graduated that the sound travels at a speed of 1km in 3 seconds.*

• Under the condition of temperature of 20^ C( 68^ F) .

CAUTION

The telemeter provides only a rough indication of the distance to the place where lightning struck, and therefore, the indication cannot be used as the guideline to avoid the danger of lightning. It should also be noted that the speed of the sound differs depending on the temperature of the atmosphere where it travels.

HOW TO USE THE TELEMETER

Before beginning, check that the stopwatch has been reset.

START

(Flash of light)

Press button A to start the stopwatch as soon as you see the light.

STOP

(Crash of thunder)

2 When you hear the sound, press button A to stop the stopwatch.

3 Read the telemeter scale that the stopwatch second hand points to.

Please note that the stopwatch second hand moves in 1-second increments and does not always point exactly to the graduations of the telemeter scale. The telemeter scale can be used only when the measured time is less than 60 seconds.

BATTERY CHANGE

3 Years

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 SR927W battery.

• If the stopwatch is used for more than 2 hours a day, the battery life may be less than the specified period.
• After the battery is replaced with a new one, set the time/calendar and adjust the stopwatch hand position.

Battery life indicator

When the battery nears its end, the small second hand moves at two-second intervals instead of normal one-second intervals. In that case, have the battery replaced with a new one as soon as possible.

• The watch remains accurate while the small second hand is moving at two-second intervals.

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 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.

NECESSARY PROCEDURE AFTER BATTERY CHANGE

After the battery is replaced with a new one, or when an abnormal display appears, follow the procedures below to reset the built-in IC. The watch will resume its normal operation.

1. Pull out the crown to the second click.
2. Press Button A and B at the same time.
3. Push the crown back in to the normal position and check if the hands move as normal.

• Resetting the IC will initialize the watch. Before starting to use the watch, it will be necessary to set the time and adjust the STOPWATCH hands to the "0" position. Refer to "TIME AND CALENDAR SETTING AND STOPWATCH HAND POSITION ADJUSTMENT" section of this manual.
