The minute repeater
On demand, the minute repeater strikes the
hours, the quarter-hours, and then the minutes
that have elapsed since the last quarter-hour. The
first hammer strikes the hours on the low-pitched
gong with one strike for each hour. Subsequently,
each quarter-hour is sounded as an alternating
double strike by two hammers on both the high-
and low-pitched gongs. Finally, the second ham-
mer strikes the high-pitched gong to count the
number of minutes that have passed since the last
quarter-hour.
At 12:59, for instance, the melody consists of 12
low sounds, 3 double high/low sounds, and 14
high sounds (totaling the maximum of 32 strikes).
Settings
• Before you perform any corrections or settings, wind
the watch by hand (20 turns of the winding crown).
• Pull the crown out (1).
• Turn the hands forward.
• Push the winding crown home again (2).
Instructions
The strike sequence of the minute repeater must
be allowed to end completely before it is activated
again.
Caution: never actuate the winding crown as
long as the repeater is working and for 30 se-
conds thereafter. Doing so could cause damage
to the repeating mechanism which would not
be covered by the warranty.
To activate the striking mechanism, push the slide
(3) all the way up.
Now release it completely – do not pull it down.
Two small hammers will now strike the hours, quar-
ter-hours, and minutes on two gongs of low and
high pitch. If the watch was set aside unwound for
an extended period of time, the minute repeater
might not indicate the correct time because the
oil may have thickened at some points inside the
mechanism. This is absolutely normal and has no
negative consequences. The striking mechanism
will function correctly again within one or two
hours after the watch has been rewound.
Recommendations
WATER RESISTANCE
Although your watch is equipped with a water-
resistant crown, it is not protected at all against
the ingress of moisture because of the slot for the
minute repeater slide.
Therefore, exercise care to ensure that liquid does
not come into contact with your watch.
SERVICE
We recommend that you have your watch ser-
viced at least once every three to five years. For
this purpose, we suggest you take it to an Autho-
rized Patek Philippe Retailer who will send it
to our Geneva manufacture, the only location
authorized to service watches with minute repea-
ters. You can then be assured that your watch will
be inspected and overhauled by a qualified mas-
ter watchmaker at Patek Philippe headquarters in
Geneva.
