○ The battery life shown above is for a watch with a new battery.

※ However, if the stopwatch is used for more than 2 hours a day, the battery life may be less than three

years.

○ The battery in the watch at the time of purchase is a monitor battery inserted in the watch at the factory

for performance checks, therefore, the battery may run down earlier than the above-specified period.

○ When the battery is exhausted, the second hand moves at two-second intervals.

While the small second hand is moving at two-second intervals, the time accuracy is not affected.

○ The accuracy is under the condition that the watch is worn on the wrist in a normal temperature range

between 5 ℃ and 35 ℃.

○ Operational temperature range is -10 ℃∼+60 ℃(14<∼140<)

Lumibrite

[If your watch has lumibrite]

LumiBrite is a luminous paint that is completely harmless to human beings and natural en-

vironment, containing no noxious materials such as radioactive substance.

LumiBrite is a newly-developed luminous paint that absorbs the light energy of the sunlight

and lighting apparatus in a short time and stores it to emit light in the dark.

For example, if exposed to a light of more than 500 lux for approximately 10 minutes,

LumiBrite can emit light for 5 to 8 hours. Please note, however, that, as LumiBrite emits

the light it stores, the luminance level of the light decreases gradually over time. The dura-

tion of the emitted light may also differ slightly depending on such factors as the bright-

ness of the place where the watch is exposed to light and the distance from the light

source to the watch.

(A) Sunlight

[Fine weather]: 100,000 lux [Cloudy weather]: 10,000 lux

(B) Indoor (Window-side during daytime)

[Fine weather]: more than 3,000 lux [Cloudy weather]: 1,000 to 3,000 lux

[Rainy weather]: less than 1,000 lux

[Distance to the watch: 1m]: 1,000 lux

[

Distance to the watch: 3m]: 500 lux (average room luminance) [Distance to the watch: 4m]: 250 lux
