The first step in removing the move-
ment from the case
is
to
remove the
caseback.
Insert a knife
blade
in
the opening notch on the bezel
and
snap the caseback
off
. The locating
tab
on the caseback
is
used
for
orientation
of
the
back
during
re-assembly.
The movement
is
protected
by
a
movement cover having access
for
regulation. The
energy
cell
is
loose
and
may be removed
for
testing.
Any
energy cell with a
voltage
of
less
than 1.5 volts,
or
one which
is
known
to
have been
in
service
in
excess
of
one year, should be re-
placed. *
Avoid
short circuiting
of
the cell
by
metallic connections
between the
outer
case
and
the
negative pole
as
this short circuit
could shorten the life
of
the cell.
The movement cover
may
now
be
removed. It
is
held
in
place
by
two
tabs which seat
in
a recess in the
bezel.
The movement
will
stay with the
bezel since
it
can
only
be removed
through the crystal side.
