Do not use the watch in scuba diving or saturation diving.
The various tightened inspections under simulated harsh environment, which are
usually required for watches designed for scuba diving or saturation diving, have
not been conducted on the water resistant watch with the BAR (barometric
pressure) display. For diving, use watches specifically designed for diving.
Do not pour running water directly from faucet.
The water pressure of tap water from a faucet is high enough to degrade the water
resistant performance of a water resistant watch for everyday life.

Mechanical watch characteristics (Hand-wound, auto-wound)

1
• This is a mechanical watch powered by a spring.
• To use it from a stopped state, turn the crown 20 turns by hand to wind up the spring before starting the
watch.
• Although the accuracy of quartz watches is measured in differences over months or years, in mechanical
watches it is measured in differences per day (i.e., the amount the watch speeds up or slows down in a
single day).
• Additionally, mechanical watches are subtly affected by the conditions in which they are used (e.g.,
duration worn, temperature, arm movement, the amount wound, etc.) ; thus, the amount of error is not
constant.
• When affected by a strong magnetism from outside, the mechanical watch may lose/gain time. 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.

Please note that there is a risk of minor injury or material damage if the following safety
regulations are not strictly observed.
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 CUSTOMER SERVICE CENTER.
Do not leave moisture, sweat and dirt on the watch for a long time.
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 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.
