Be aware of a risk that a water resistant watch may lessen its water
resistant performance because of deterioration of the adhesive on
the glass or gasket, or the development of rust on stainless steel.
Do not leave moisture, sweat and dirt on the
watch for a long time.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring may accelerate the
deterioration of water resistant performance of the watch.
CAUTION
Do not turn or pull out the crown when the
watch is wet.
Water may get inside of the watch.
※ If the inner surface of the glass is clouded with condensation or water droplets appear
inside of the watch for a long time, the water resistant performance of the watch is
deteriorated. Immediately consult the retailer from whom the watch was purchased or
SEIKO CUSTMER SERVICE CENTER (listed on the back cover).

Magnetic resistance
(affect of magnetic field)
SEIKO Diver's Watches are hard to come under magnetic influence
of the outside. (JIS level-1 standard)
JIS level-1 standard:Keep the watch more than 5 cm away from magnetic products.
※
When affected by a strong magnetism from outside, the mechanical watch may lose/gain time
temporarily. The parts of the watch may become magnetized depending on the extent of the effect. In
such a case, consult the retailer from whom the watch was purchased since the watch requires repair
including demagnetizing.

The reason why analogue
quartz watch is affected
by magnetism.
It is because the built-in motor of the watch, which harnesses
magnetic power and external strong magnetism, affect each other
to stop the motor or suppresses the turn of the motor.
