The TIMEX• SSQ•watch is designed
to
withstand
water
pressure
to
50
lbs. p.s.i.a. (equals immersion
to
80
feet
below sea level)
and
is dust-resistant, as long as window,
control buttons
and
case remain
intact.
Servicing your
TIMEX
SSQ,
NOTE;
If
watch stops
or
shows incorrect
time
for
no
apparent reason, make sure
that
the
raised button has
not
bsen inadvertently rotated
out
of
the normal
'·on" position.
If
your
TIMEX

The
"excitable
.. Quartz Crystal.
Quartz
is probably as
old
as
our
planet
It
is
a
common
mineral
with an
uncommon
characteristic.
It
seems inert.
But
when connected
to
proper
electronic
circuits.
it
will
pulsate
at
a steady,
unvarying
rate.

What
makes
the
TIMEX
SSQ so
accurate.
This is the timekeeping system of the
TIMEX
SSQ
.
All
its
major
circuits
are integrated
on
a tiny silicon
chip
containing over 2,000 transistors
in
an area
approxirr;;~e
!;.
/. inch square. The system is powered
by
