the
TIMEX
Model
23
Movement
The
Time
x Model
23
is
o 6
3,4
" '
x
8"
'
movement
featuring
"V
-conic"
bearings
system
and
rugged
t
wo
plate
design.
Whereas
most
watches
utilize
bridges,
Timex
has
constructed
the
Model
23
movement
with full
plates
to
take
advantage
of
the
accuracy
inherent
in
this
type
of
design.
This
accuracy
i
nsures
complete
interchangeability
far
the
escape-
ment
and
gear
train
without
the
need
for selective
fitting
and
adjustments
which
complicate
the
repair
of
most
watches.
To
clean
the
Timex
Model
23,
it is
necessary
to
remove only
the
mi
nute
hand,
dial
and
balance.

proper
procedures
.
Timex
has
found
,
through
long
and
careful
research,
that
the
best
method
of
cleaning
is with
only
the
above-mentioned
parts
removed
.
The
clean-
ing fluid, while removing
any
contamination
from
the
movement,
will
also
re-
move
oil from
the
gear
train
,
pivots
and
holes.
If
further
di
smantling
is r
equired,
removal
of
the
movement
plate
will
expose
the
gear
train
and
associated
parts
.
Reassembly
should
start
with
the
movement
plate,
exercising
normal
care
to
insure
proper
positioning of pivots in
their
respective
holes.
The
exploded
view
of
the
movement

reassembly.

Removing
the
Balance
Two
"V-conic"
studs
ore
used os
bearings
for
the
balance
staff
on
the
Timex Model
23
movement
.
The
stud
on
the
movement
plate
is
driven into
a screw so
that
fine
endshake
adjust-
mel']t
is
possible.
Removal of
the
balance
assembly
should be carried
out
in
the
follow-
ing
manner
:
a)
Remove
the
hairspring wedge pin,
being careful
not
to
distort
either
the
pin or
the
hairspring.
b)
Rotate
the
balance
slowly until
the
hairspring tail is free
of
the
hairspring wedge pin
bracket
and
the
regulator
.
c)
Loosen
the
balance
screw assembly
(counterclockwise
direct
i
on)
using
a
suitable
screwdriver,
unt
il
the
end
of
the
balance
staff
is
free
ot
the
"V
-conic"
bear
ing. During
the
loosening of
the
screw, only
mm1mum downward pressure
should be
applied
with
the
screw-
driver,
as
excessive downward
pressure could seriously
damage
the
balance
staff
points.
dl
Carefully remove
the
balance
as-
sembly.

Cleaning
the
Model
23
Movement
After
removal
of
the
balance,
ond
the
other
ports
mentioned
in
Pages
23.3
through
23.5,
the
movement
is
ready to
be
cleaned
.
If o
cleaning
machine
is
used, place
the
movement
in
the
basket
with
the
dial
plate
down
to
insure
proper
drainage
of
the
fluid from
the
mainspring
barrel.
It should
be
well swirled
in
the
cleaning
fluid
after
which two
sets
of
rinsing
fluid should
be
used.
The
final
cleaning
fluid
must
be
absolutely
clean.
After
cleaning,
the
movement
should be thoroughly dried.
If a
cleaning
machine
is
not
available,
the
same
procedure
should
be
followed
manually,
by re-inserting
the
stem
,
grasping
the
movement
firmly
around
the
stem
and
shaking
it
in
the
cleaning
ond
rinsing fluids
to
insure
that
the
fluid
will
pass
through
the
entire
mechanism.
The
balance
assembly should
be
cleaned
separately
in
a small
jar
to
prevent
damage
to
the
hairspring.
Only
standard
watch
cleaning
solutions should
be
used
throughout
.
•
Lubricating
the
Model
23
Movement
The
movement
should
be
re-oiled
in
the
normal
manner
using only high
grade
watch
oils (oil used
in
factory
assembly
is
Elgin
M56b)
.
The
mainspring
is
per-
manently
lubricated
with a solid
coating
which
is
not
affected
by normal
clean-
ing solutions
and
should,
therefore,
not
be
ailed.
The
"V
-
conic"
bearings
should
be
oiled no less
than
3,4
full
before
replacing
the
balance
.

Reassembly of the Model 23 Movement
V- CONIC BEARING
DIAL PLATE
BALANCE w
MOVEMENT PLATE
Replace the balance carefully into
the movement by tilting the wheel
and inserting first, the movement
side pivot (hairspring side) then,
the dial side pivot into the "V-
conic bearing". Adjust the balance
screw enough to hold the balance in
place . By rotating the balance , insert
the hairspring into the regulator slot
and hairspring wedge pin bracket. Be-
fore
re-pinning the hairspring, make
certain the impulse pin is within the
slot on the fork. Repin the hairspring
making sure that the wedge pin is
straight and true, as any distortion to
the pin could interfere with the
normal "breathing" of the hairspring .
The endshake is now finally adjusted
using caution to apply only minimum
downward pressure to the balance
screw as excessive pressure could
damage the points of the balance
staff .
Inspect
the hairspring to be certain
that it is properly adjusted. As shown
by the diagram, the hairspring should
be positioned central ly within the
hairspring slot .
