watch
cleaning machines (including
ultrasonic baths).

in the machine
with
the Dial
Plate

to
insure
proper
drainage
of
the
fluid
from the mainspring barrel.
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
Assembly must be cleaned
separately
in
order
to prevent
damage

the Balance
Staff
Points

the Hairspring. The cleaning procedure
is
as described
above
.
Other
metal parts
may
be cleaned
as
described
above

the movement.
Only
standard
watch cleaning solutions should be used in the cleaning
procedures described
above
.
Caution
must be exercised when cleaning Cases, Dials, Hands, Special Rings,
etc. which
may
contain materials
other
than metal because
paint,
lacquer
and

damaged
by
some
standard
watch cleaning solutions.
