Striking mechanism
At the pre-set time, the alarm will strike at a
steady cadence for a total duration of about 35
seconds. You can also stop it sooner by pressing
the alarm’s on/off pusher at 2 o’clock after having
unlocked it. At the end of the strike sequence
or when you stop it using the pusher, the bell-
shaped aperture changes from white to black.
Recommendations
WATER RESISTANCE
Your watch is fitted with different types of seals
to protect the movement against the ingress of
dust and moisture and to prevent damage if it is
immersed in water. Nonetheless, we recommend
that you prevent direct contact with water if your
watch has a leather strap.
It is advisable to have a water-resistance test
carried out every year on your watch. This is a
simple procedure that takes only a few minutes
at a properly equipped point of sale.
SERVICE
We recommend that you have your watch
serviced at least once every three to five years.
For this purpose, we suggest you take it to an
Authorized Patek Philippe Retailer who will
send it to our Geneva manufacture, the only
location authorized to service watches with
minute repeaters. You can then be assured that
your watch will be inspected and overhauled by
a qualified master watchmaker at Patek Philippe
headquarters in Geneva. The master watchmaker
will completely disassemble the movement
and then inspect, clean, and lubricate all the
individual parts prior to reassembly. All functions
of the watch will also be tested in detail and the
escapement regulated if necessary. Finally, its
rate accuracy will be monitored and precision-
adjusted for a further period of at least two weeks.
The case and the buckle will be polished as per
your instructions and your watch will be returned
