Introduction
The grand complication with a minute repeater
and a perpetual calendar sports a new face and
a platinum case with gentle cambers and rounds
emphasized by the concave bezel and the satin-
finished, recessed flanks. The black dial in genuine
enamel carries applied Breguet numerals and
recessed counters.
The minute repeater
On demand, the minute repeater strikes the hours,
the quarter-hours, and the minutes that have elapsed
since the last quarter-hour. One hammer strikes the
hours on the low-pitched gong once 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
hammer strikes the high-pitched gong to count the
number of minutes that have passed since the last
quarter-hour.
12 low strikes, three double high-low strikes, 14 high
strikes: This constitutes the melody with a total of
32 strikes at 12:59.

Caliber R 27 Q
Self-winding wristwatch with
minute repeater and perpetual calendar.

The “cathedral” gongs
To optimize the acoustic quality of a minute-
repeater wristwatch, the “cathedral” gongs
are shaped to encircle the movement not just
once, but nearly twice. This makes them almost
twice as long as conventional gongs. The result:
greater vibrational stability and better acoustic
characteristics.
The perpetual calendar
The perpetual calendar indicates the date, the day
of the week, the month, and the leap-year cycle,
automatically taking into account months with
28, 29, 30, and 31 days. It switches directly from
September 30 to October 1 or from February 28
to March 1. In leap years, it indicates February 29
before switching to March 1.
If the watch is worn regularly or kept in a winder,
the perpetual calendar mechanism will require
no manual correction until February 28, 2100, a
secular year in which, as an exception, February
29 is skipped.

SETTING THE CALENDAR DISPLAYS
PREPARATIONS PRIOR TO SETTING
SETTING THE MOON PHASE
• Before performing any corrections or settings,
always wind the watch (20 turns of the winding crown).
• Pull the crown (8) out.
• Advance the hands clockwise until the day-of-week
hand (6) and the date hand (4) switch forward by one day.
• Set the hands to 7 am.
• Push the winding crown (7) home again.
• Actuate the correction push piece (A) as many times as
needed to align the date hand (4) with the current date.
• Actuate the correction push piece (B) as many times as
needed to indicate the correct year (1) (2016 = leap
year IV ; 2017 = I ; 2018 = II) and then the current month
(2).
• Actuate the correction push piece (D) as many times as
needed to display the current day of the week (6).
• Actuate the correction push piece (C) as many times as
needed to display the full moon in the moon-phase
aperture (3).
• Consult the “Full Moon Calendar” annexed to these
instructions to find out how many days have elapsed
since the last full moon and actuate the correction push
piece that many times (without the day of the last full
moon).

Minute repeater
The strike sequence of the minute repeater
must be allowed to end completely before it
is activated again.
Caution: Under no circumstances should
you manipulate the winding crown while
the minute repeater is striking the time and
during 30 seconds 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
(9) all the way up.
Now release it completely - do not pull it down.
Two small hammers will now strike the hours,
quarter-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 to two
hours after the watch has been rewound.
Recommendations
WATER RESISTANCE
Although your watch is equipped with seals for
the crown, it is not protected 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.
HAVING YOUR WATCH SERVICED
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.
SETTING THE TIME
• Pull the crown (8) out.
• Set the hands to the correct time. If you advance the
hands beyond midnight, all displays of the perpetual
calendar will be advanced as well.
• After having set the time, push the crown (7) home
again.

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
to you in mint condition. The entire process may
take several weeks because each watch must
undergo a complete series of tests to fulfill the
strict quality criteria of Patek Philippe.
If you have any questions regarding the
maintenance of your watch, contact the
Authorized Patek Philippe Retailer nearest you or
our International Customer Service department in
Geneva, or visit www.patek.com.
WINDING
Your watch is wound automatically by the
movements of your wrist, which set a winding
mechanism in motion. When fully wound and off
the wrist, you watch has a power reserve of at least
38 hours. If it was set aside for a longer period of
time and is no longer running, it can be manually
wound with about then turns of the crown.
We advise you to wind the watch before you put
it on. This way, you can avoid lateral pressure on
the winding stem which in the course of the years
could damage the stem tube.
The same applies to handsetting. Please use your
fingernails to pull the crown out and turn it gently
between two fingertips.
WATCH WINDER
Your Ref. 5374 is delivered with a winder. Keep
your watch in this box if you intend not to wear
it for a longer period of time. The rotation of the
watch holder will keep it wound and you will not
have to reset the time when you put your watch on
again. Within 24 hours, the winder will move your
watch during 8 hours and let it rest for 16 hours.
PATEK PHILIPPE SEAL
As a comprehensive seal of quality, the Patek Philippe
Seal applies to the entire watch, including the
movement, case, dial, hands, pushers, strap, and clasp
as well as to all other facets that contribute to the
precision and visible appearance of the timepiece. Its
applicability to the technical, functional, and aesthetic
aspects of the watch takes into consideration not
only the artisanship with which it was crafted, but
also covers its rate accuracy, its dependability, and
the quality of customer service. Moreover, it stands
for the entire know-how and all the special skills
invested in the development, production, and long-
term maintenance of an extraordinary timepiece.
CHANGING THE CASE BACK
Your watch comes with a sapphire-crystal case
back as well as with an interchangeable solid-metal
back. Only qualified master watchmakers at the
Patek Philippe workshops in Geneva are authorized
to exchange the backs.

Introduction
La Grande Complication à répétition minutes et
quantième perpétuel prend un nouveau visage
avec un boîtier en platine tout en courbes et en
rondeurs, rehaussé par une lunette concave et
des flancs finement creusés et satinés. Le cadran
en émail véritable noir s’orne de chiffres Breguet
appliques et de compteurs en creux.
La répétition minutes
La répétition minutes sonne, à la demande, les
heures, les quarts ainsi que les minutes écoulées
depuis le dernier quart, sur deux timbres
«cathédrale» à la pureté cristalline, réalisés dans un
acier bénéficiant d’excellentes qualités acoustiques.
Le premier marteau sonne les heures en frappant
un coup par heure écoulée sur le timbre grave; la
sonnerie des quarts est ensuite assurée par deux
marteaux qui frappent alternativement sur le timbre
aigu puis sur le timbre grave. Le deuxième marteau
vient ensuite frapper, sur le timbre aigu, le nombre
de minutes écoulées depuis le dernier quart. 12 coups
graves, 3 double coups, 14 coups aigus: ainsi se fait
entendre le son mélodieux de 12 heures 59 minutes
(totalisant le maximum de 32 coups).
