MOON PHASE DISPLAY (Cal. 7F38 and 7F39)
@ The phases (waxing and waning) of the
moon are displayed by the shapes which a
circle (the moon) and the double-moun-
tain-shaped opening on the dial combine
to form.
@ The. moon phase (age of the moon) is
expressed by the number of days which
elapse from the time of a new moon to
the noon of a certain day. It moves in a
cycle of approximately 29.5 days from
one new moon to the next.
e The illustration below will be helpful to you in reading the moon phase. It
is intended to show the age of the moon only and not the exact shapes of
the moon.

DUAL
TIME
FUNCTION
1;
The
main
time
display
and
the
24-hour
time
display
can
be
set
independent-
ly
to
indicate
different
time
zones.
Thus,
if
you
are
traveling
out
of
town,
your
watch
can
display
home
time
on
the
main
time
display
and
local
time
on
the
24-hour
time
display,
or
vice-versa.
The
additional
hour
hand
can
indicate
the
time
that
is
a
given
number
of
hours
ahead
of
or
behind
the
main
time
display.
The
additional
hour
hand
interlocks
with
the
main
time
display
so
that
the
time
difference
previously
set
will
be
automatically
maintained.

PRECAUTIONS
ON
CROWN
AND
BUTTON
OPERATION
It
is
recommended
that
each

button
should
be
operated
separately.
However,
if
they
are
operated
at
the
same
time,
please
observe
the
following:
1.
If
crown
“B"
is
pulled
out
to
the
first
click
with
crown
“A”
pulled
out
to
the
second
click,
crown

will
not
operate
to
set
the
24-hour

s WATER RESISTANCE
e Non-water resistance
if
“WATER

your
watch
is
not

resistant,
and
care
should
be
taken
not
to
get
it
wet
as
water
may
damage
the
movement.
lf
the
watch
becomes
wet,
we
suggest
that
you
have
it
checked
by
an
AUTHORIZED
SEIKO
DEALER
or
SERVICE
CENTER
to
make
sure
that
no
water
damage
occurred.
e Water resistance (3 bar)

to
withstand
up
to

We
recommend
that
you
wear
a

SEIKO
Diver's
watch
for
scuba
diving.
If
used
in
sea
water,
rinse
the
watch
in
fresh
water
and
dry
it
com-
pletely.
Do
not
operate
the

NOTE:
Pressure

to
increase

® SHOCKS
Light activities will not affect.your watch, but be careful not
to drop your watch or hit it against hard surfaces as this may
cause damage. °
=» MAGNETISM
Your watch will be adversely affected by strong magnetism.
Keep it away from close contact with magnetic objects.
=» TEMPERATURES
Your
watch
works
with
stable
accuracy
between
a
temperature
range of 5°C and 35°C (41°F and 95°F).
@ High temperature
Temperature
over
60°C
(140°F)
may
cause
battery
leakage
or shorten the battery life.
® Low temperature
Do
not
leave
your
watch
in
very
low
temperature
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 corrected when. the
watch returns to normal temperature.
= CHEMICALS
Be careful not to expose the watch to solvents (e.g., alcohol
and gasoline), mercury (i.e. from a broken thermometer),
cosmetic spray, detergents, adhesives or paints. Otherwise, the
case, bracelet, etc. may become discolored, deteriorated or
damaged.
=» PERIODIC CHECK
It is recommended that the watch be checked once every 2
to 3 years. Have your watch checked by an AUTHORIZED
SEIKO DEALER or SERVICE CENTER to ensure that the
case, crowns, button, gasket, and crystal seal remain intact.
=CARE OF CASE AND BRACELET
To prevent possible rust on the case and bracelet caused by
dust and moisture, wipe them with a soft dry cloth.

BATTERY CHANGE
3
Years
The
miniature
battery
which
powers
your
watch
should
last
approximately
3
years.
However,
because
the
battery
is
in-
serted
at
the
factory,
its
actual
life
once
in
your
possession
may
be
less
than
the
specified
period.
When
the
battery
expires,
be
sure
to
replace
it
as
soon
as
possible
to
prevent
any
possible
malfunction.
For
battery
replacement,
we
recommend.
that
you
contact
an
AUTHORIZED
SEIKO
DEALER
and
request
SEIKO
SROIGSW
battery.
However,
if
this
battery
is
not
available,
then
use
Maxell
SR916SW
or
Matsushita
SR916SW
battery.

two-second
intervals
instead
of
