• there are no visible cracks in the crystal or the watch band.

• the strap or bracelet is securely fastened to the watch case.

• the buckle keeps the strap or bracelet firmly secured to the wrist.

■ TEMPERATURES

Your watch works with stable accuracy within a temperature range of 5° C

+60°C

and 35° C (41° F and 95° F). Temperatures over 60° C (140° F) may cause
battery leakage or shorten the battery life. Do not leave your watch in very

-10°C

low temperatures below –10° C (+14° F) for a long time since the cold may
cause a slight time loss or gain. However, the above conditions will be

10

corrected when the watch returns to normal temperature.

■ MAGNETISM

S

N

Your watch will be
adversely affected by
strong magnetism.

of the case and bracelet, wipe
them periodically with a soft
dry cloth.

Be careful not to expose the
watch to solvents, mercury,
cosmetic spray, detergents,
adhesives or paints. Otherwise,
the case, bracelet, etc. may
become discolored,
deteriorated or damaged.

■ CHEMICALS ■ PERIODIC CHECK

It is recommended that the watch
be checked once every 2 to 3
years by an AUTHORIZED SEIKO
DEALER or SERVICE CENTER to
ensure that the case, crown,
gasket and crystal seal remain
intact.

LUMIBRITE

LumiBrite is a newly developed luminous paint that is completely harmless to human beings and

the natural environment, containing no noxious materials such as radioactive substances.

LumiBrite absorbs the energy of sunlight or artificial light in a short time and stores it to emit

English

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 duration of the emitted light may also differ slightly depending
on such factors as the brightness of the place where the watch is exposed to light and the distance
from the light source to the watch.

When you make a dive in dark water, LumiBrite may not emit light unless it has absorbed and
stored light sufficiently

Before diving, therefore, be sure to expose the watch to light under the conditions specified
above, so that it fully absorbs and stores light energy. Otherwise, use the watch together with an
underwater flashlight.

< Reference data on luminance >

(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

(C) Lighting apparatus (40-watt daylight fluorescent light)

[Distance to the watch: 1 m]: 1,000 lux
[Distance to the watch: 3 m]: 500 lux (average room luminance)
[Distance to the watch: 4 m]: 250 lux
