Patek Philippe NAUTILUS 240 PS IRM C LU Handbuch Seite 10

CAUTION
The crown must be completely unscrewed
before you can wind the watch or set the
time.
Please wind the watch and set the time before
you put the watch on. This prevents lateral
pressure on the winding stem. Please use
your fingernails to pull the crown out and
turn it gently between two fingertips.
Never pull out the crown in a humid envi-
ronment or underwater: the water resist-
ance of your watch is assured only when the
crown is pushed home and screwed down.
Correction push pieces should be actuated
exclusively with the correction stylus that
was delivered with the watch. The use of
any other tool could damage your timepiece.
If your watch has stopped running, rewind
it by hand before performing any correc-
tions or adjustments (about 10 clockwise
turns of the crown).
Do not perform any date or moon phase
correction between 9 p.m. and 1 a.m.
Every year, the date must be corrected five
times – at the end of each month that has
fewer than 31 days.
