CAUTION
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).
Disable the movement if you do not intend
to use your watch for an extended period of
time. This prevents unnecessary discharg-
ing of the battery.
We recommend that you take your watch
to an Authorized Patek Philippe Retailer
for any battery replacement.
Do not perform any date correction between
9 p.m. and 12:30 a.m.
Every year, the date must be corrected five
times – at the end of each month that has
fewer than 31 days.
