Patek Philippe is unveiling a new self-winding
grand complication that adds a 24-hour alarm to
its exclusive Travel Time display with two time
zones; the alarm signal is struck by a hammer
on a classic gong: Ref. 5520. To achieve this, the
manufacture created a totally new integrated
movement composed of 574 parts. Four patents
applications were filed for the alarm mechanisms.
It is the result of five years of development. A
noteworthy detail: the Alarm Travel Time is
Patek Philippe’s first chiming timepiece with
a water-resistant case. A quintessential travel
companion presented in an elegant Pilot-style
platinum case.

Preparations
Please manually wind the watch before
performing any corrections or adjustments
(20 counterclockwise turns of the crown).
You can be sure that performing adjustment is
safe if you first set your watch to 7 a.m.; observe
the color of the day/night indicator (LOCAL)
(white).

Setting the time – home time
Recommended method:
The reference time for your watch is the time at
home. To set the time, first unlock the correction
pushers “+” and “–” (1/4 turn counterclockwise)
and actuate one of the two pushers as many times
as needed to superpose the skeletonized and
solid hour hands and to display the same color
in the day/night indicator aperture (HOME) and
(LOCAL).
Now, pull the crown gently all the way out to
position 3 and move the hands in either direction.
The day/night indicator in the aperture (HOME)
lets you check whether you have set the correct
time (white = from 6 a.m. to 6 p.m.; blue = from
6 p.m. to 6 a.m.).
Once you have set the correct time, push the
crown home again and lock the corrections
pushers (1/4 turn clockwise).
Second time zone
Your watch has two central hour hands:
- The solid hand displays local time (the time
zone in which you are currently located)
- The skeletonized hand displays home time (your
normal place of residence or work)
When you are at home and therefore local time
and home time are the same, the hands are
perfectly aligned to appear as one.
When you change time zone, you can move the
local hour hand forward or backward one hour at
a time using the pushers on the side of the case
at 8 o’clock and 10 o’clock. During this time, the
skeletonized hand continues to indicate the time
in your home time zone. This useful feature is
intelligently combined with day/night indicators,
clearly distinguished by the words LOCAL and
HOME. These small apertures tell you what part
of the day it is in each of the two displayed time
zones.
CAUTION: The pushers used to set the local time
and to turn the alarm on and off feature a patented
safety lock that prevents inadvertent changes to
the local time and to the alarm setting. Before
they can be actuated, they must be unlocked
with a quarter turn in the counterclockwise
direction. After setting the local time or once the
alarm has been activated or deactivated, lock the
pushers again with a quarter turn in the clockwise
direction.

When the two hour hands are separate, the
skeletonized hand continues to display the time
in your home time zone, and the day/night
aperture (HOME) indicates whether it is day or
night in your home time zone.
As soon as you have returned to your home time
zone (normal place of residence or work), simply
press the correction pusher “+” or “–” as many
times as needed to superpose the two hour hands
and again. Make sure the two day/night indicators
(HOME) and (LOCAL) have the same color. Lock
the pushers again with a quarter turn in the
clockwise direction.
Date correction
The date indicated by your watch refers to the
local time zone. To set the date, actuate the
correction push piece between 6 and 7 o’clock as
many times as needed to display the current date.
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.
CAUTION: The date cannot be adjusted between
10 p.m. and 2 a.m. If you activate the date change
mechanism during this time, an insulator will
prevent the date from being changed to avoid any
damage to the movement.
Display of a second time zone
- local time
Before you set a second time zone, check the
day/night indicator (HOME) to make sure that the
two superposed hour hands indicate the correct
time at home and that the day/night indicator
correctly displays daytime or nighttime hours, for
instance 8 a.m. or 8 p.m.
To set the local hour hand to display a second
time zone, follow these steps:
- If you are traveling eastbound, press the
correction pusher “+” at 8 o’clock to move the
solid hand clockwise by as many hours as the
two time zones are apart
(press once = +1 hour);
- If you are traveling westbound, press the
correction pusher “– ” at 10 o’clock to move the
solid hand clockwise by as many hours as the
two time zones are apart
(press once = –1 hour);
- If you move the hour hand for local time
beyond midnight in either direction, the date
will also switch forward or backward;
- If you continue your journey and pass through
further time zones, simply repeat the procedure
described above with the pushers “+” or “–”.

Activating/deactivating the alarm
CAUTION: The alarm cannot be actuated unless
the strikework barrel is fully wound.
To be able to actuate the alarm, make sure that
you always wind the striking mechanism to the
full extent. If the winding is not complete, the
alarm cannot be actuated. To wind the strikework
barrel turn the crown at 4 o’clock in the clockwise
direction. For this, the crown must be pushed
home to position 1.
Since your watch is equipped with a dynamometric
crown you will know that the strikework barrel is
fully wound when you hear a succession of soft
clicks.
To actuate the alarm, unlock the alarm
pusher at 2 o’clock (by giving it a quarter turn
counterclockwise) and then press it. The bell-
shaped aperture will change from black to
white. If it does not change, this means that
the strikework barrel has not been fully wound.
Remember to lock the pusher (by a quarter turn
clockwise) to avoid accidentally deactivating the
alarm.
Once the alarm has sounded, the strikework
barrel must be fully rewound before you can
reactivate the alarm mechanism.
Setting the alarm
The alarm time, like the date, is synchronized
with the local time (solid hour hand).
The alarm time can be programmed in quarter-
hour steps and up to 23 hours in advance. The
alarm can be set to strike as from the next quarter
hour: for example, it can be set at 9.20 to sound
at 9.30.
To adjust the alarm time, pull the crown out
to position 2. Then turn the crown backwards
or forwards until the desired time appears in
the double aperture at 12 o’clock. The day/
night indicator situated just below the aperture
enables you to check whether the time displayed
corresponds to 1 a.m. (blue indicator from 6 p.m.
to 6 a.m.) or 1 p.m. (white indicator from 6 a.m.
to 6 p.m.). Once the alarm time is set, push the
crown home again (position 1).
You can proceed with programming a new alarm
time as soon as the watch has finished striking.
But to reactivate the alarm for the same time the
next day, please wait 60 minutes.

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

to you in mint condition. The entire process will
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 to you
or our International Customer Service department
in Geneva, or visit www.patek.com.
WINDING
When it is on your wrist, your watch is wound
automatically by your arm movements. When
fully wound and off the wrist, you watch has a
power reserve of at least 52 hours. If your watch
stopped because you set it aside for an extended
period of time, you can wind it manually with
about 20 counterclockwise 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 and alarm time
setting, for which we advise to use your fingernails
to pull the crown out and turn it gently between
two fingertips.
CHANGING THE CASE BACK
Your watch comes with a sapphire-crystal case
back and a separate interchangeable solid metal
back. Only watchmakers entitled by Patek
Philippe Genève are authorized to exchange the
backs.
PATEK PHILIPPE SEAL
The Patek Philippe Seal is a global emblem of
quality that applies to the completed and fully
cased watch. It covers the movement, the case,
the dial, the hands, the pushers, the straps
and bracelets, the clasps, as well as all other
components that contribute to the accuracy and
aesthetic appeal of a watch. It takes technical,
functional, and designrelated aspects into
account and also covers the visual appearance of
the watch, its rate accuracy and dependability,
as well as the quality of the customer service
to which its owner is entitled. It encompasses
the entire know-how and the unique facets that
govern the development, production, and long-
term maintenance of an exceptional timepiece..
