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.

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.

s WATER RESISTANCE
e Non-water resistance
if
“WATER
RESISTANT”
is
not
inscribed
on
the
case
back,
your
watch
is
not
water
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)
if

is
designed
and
manufactured
to
withstand
up
to
3
bar,
such
as
accidental
contact
with
splashes
of
water
or
