Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or miles and STOPWATCH 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

2. Tachymeter scale indicated by STOPWATCH second hand gives the average number of jobs accomplished per hour.

Ex. 2: If 15 jobs are completed in 20 seconds:
"180" (tachymeter scale figure) x 15 jobs = 2700 jobs/hour

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.

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.
