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 
SSQ 
should ever need servicing, send 
it

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 
a 
s-..a 
T \·Ex Energy Cell.
