Cleaning
the
Model
253 Movement
The
best
way
to
clean
the
Model
253
movement
is
to
disassemble
the
movement
only
to
the
point
of
removing
the
balance
bridge
and
the
balance
wheel
assembly
.
The
movement
should
be
placed
in
the
watch
cleaning
machine
(including
ultrasonic
baths),
preferably
on
edge
to
insure
proper
drainage
of
the
fluids.
The
movement
must
be
emersed
in
two
sets
of
rinsing fluid.
The
final rinsing
solution
must
be
absolutely
clean.
After
cleaning
is
completed,
the
movement
must
be
thoroughly
dried.
The
balance
wheel
as
s
embly
must
be
cleaned
separately
in
order
to
prevent
damage
to
the
balance
staff
points
and
the
hairspring
.
Other
metal
parts
may
be
cleaned
in
the
same
manner
as
the
movement.
Only
standard
watch
cleaning
solutions
should
be
used
in
the
above
cleaning
procedures.
Caution
must
be
exercised
when
cleaning
cases,
dials,
hands,
special
rings, etc. which
may
contain
materials
other
than
metal
because
paint,
lacquer
and
plastic
finishes
can
be
damaged
by
some
standard
watch
cleaning
solutions.
