WHEN

OUT EXACTLY
WHAT
THE CUSTOMER'S PROBLEM
IS
BEFORE

For example,
let
us
assume
that
an
ACCUTRON
timepiece has
been bronchi
In
you
because
it
is
gamin*;
or Inning
lime.
You
must
find

day
or
a
minute
or
more
a
week

determine whether
It
requires
only simple regulation or
whether
the
movemenl
mufil
be
repaired.
Suppose
yon
are
told
only
llml
"it
loses"
and your
rate
recorder
indicates
a
loss of. say. 5
seconds
.i
day.
If
you
regulate
it
accordingly
nnd
return
it,
you
will
have
a very
dissatisfied
customer
if
ihe
timepiece
was
losing several
minutes
per
day
(requiring repair)
On
the odicr
hand, the timepiece
may
have been
losing several
seconds
per day, as
shown
by your
rale recorder,
In this
case,
if
you
elect to
"repair" ihe
movemenl. you
are
attempting
lo
locate
a
defect or
fault
Ihat
does
not
exist.
Such
situations
can
only
he
avoided
by
finding out
from
the
customer
the
symptoms
Ihat led
him
to
bring
the timepiece
lo
you
for correction.
