Characteristics Of Mechanical Watches（Manual Winding Model, Automatic Winding Model; Crown - Seiko Issey Miyake NE15 Instruction

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 this watch. For diving,
use special watches for diving.
Do not pour running water directly
from faucet onto the watch.
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.

Characteri s ti c s of mechani c al watches（manual wi n di n g model , automati c wi n di n g model ）
・ This is a mechanical watch that uses the mainspring as
its power source.
・ When starting to use a watch after it stops, turn the
crown approximately 20 times by hand to wind the main-
spring.
・ Accuracy of mechanical watch is indicated by a daily
rate （loss or gain per one day）, while that of quartz
watch is indicated by a monthly or annual rate.
・ Accuracy of mechanical watch may slightly vary depend-
ing on the various conditions of use （such as the length
of time during which the watch is worn on the wrist, tem-
perature environment, arm movement, and winding state
of the mainspring）.

watch was purchased or SEIKO CUSTMER 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.
