WINDING CROWN

The winding crown is used to manually wind the watch (position 1) and to set the time (position 2).

WINDING

Your watch incorporates a self-winding movement. The movements of your wrist set a centrifugal mass in motion; this tensions the mainspring, which stores the energy. When you take off your fully wound watch, it will continue to run for at least 35 hours. When it has stopped after depleting the power reserve, it can be rewound by hand (about 10 clockwise turns of the crown).

SETTING THE TIME

To set the time, gently pull the crown all the way out and move the hands in either direction. Once you have set the correct time, push the crown home again. When you turn the hands clockwise beyond midnight, the calendar displays will advance as well. We advise against turning the hands counterclockwise across midnight because this would desynchronize the calendar displays; however, it would not damage the calendar mechanism.
Your watch has a stop-seconds mechanism that halts the seconds hand as soon as you pull the crown out to position 2. This allows you to synchronize your watch with an acoustic time signal to one-second accuracy. As soon as you push the crown home (position 1), the seconds hand will start running again.

ANNUAL CALENDAR

The Annual Calendar indicates the day of the week, the month, and the date, automatically taking into account months with 30 and 31 days. If the watch is worn daily, the date only needs to be corrected on March 1 (forward by 3 days in non-leap years, and by 2 days in leap years). A calendar correction may also be necessary if the watch was set aside for a longer period of time and stopped running. If the hands are moved clockwise beyond midnight, the calendar displays will advance by one day.

• 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 environment or underwater: the water resistance of your watch is assured only when the crown is pushed home.
• 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.
• Do not perform any calendar correction between 8 p.m. and 3 a.m. or moon-phase correction between 9 a.m. and 11 a.m.
• The calendar corrections must be performed strictly in the order described below:

1. Move the hands to 6 a.m.
2. Set the date to the first day of the month
3. Correct the month
4. Correct the date
5. Correct the day of the week
6. Correct the moon phase
7. Set the time

PREPARATIONS

1. If your watch has stopped running, rewind it by hand before performing any corrections or adjustments (about 10 clockwise turns of the crown).
2. You can be sure that performing adjustments is safe if you first set your watch to 6 a.m. as follows: advance the hands beyond midnight (the date will change, otherwise, it was 12 noon) and then keep advancing the hands to 6 a.m.
3. Make sure to set the date to the first day of the month with the correction push piece at 4 o'clock (references 4946, 4947 and 4948) or at 10 o'clock (reference 5261).

DATE CORRECTION

To set the date , actuate the correction push piece at 4 o'clock (references 4946, 4947 and 4948) or at 10 o'clock (reference 5261) as many times as needed to display the current date.

Settings for References 4946, 4947 and 4948

MONTH CORRECTION
To set the month , actuate the correction push piece at 2 o'clock as many times as needed to display the current month.

DAY-OF-WEEK CORRECTION
To set the day of the week , actuate the correction push piece at 10 o'clock as many times as needed to display the current day.

MOON-PHASE CORRECTION
Each time the correction push piece at 8 o'clock is actuated, the moon-phase disk will advance by one day. To begin the correction procedure, advance the moon-phase disk until a full moon is displayed in the middle of the aperture. Consult an almanac or visit www.patek.com and count the number of days that have elapsed since the last full moon (relative to the current date). To set the correct moon phase, press the correction push piece as many times as the number of days that have elapsed since the last full moon.

MAINTENANCE

QUALITY CONTROL
The movements and completely assembled watches are subject to a series of technical tests and visual inspections to verify their rate accuracy, winding speed, power reserve, reliability, water resistance, and overall appearance. Once assembled, your selfwinding watch will run for several weeks before leaving the workshops; it fully complies with the stringent criteria of the Patek Philippe Seal.

ACCURACY
The rate accuracy of Patek Philippe watches is verified in several phases of manufacturing, both with uncased and fully cased movements. The final test is performed with a wrist motion simulator and the results must conform to the following Patek Philippe precision benchmarks:
The rate accuracy of calibers with a diameter of 20 mm or larger must range within -1 and +2 seconds per 24 hours.
The precision of a watch is determined by how accurately it keeps the time. A watch that is fast or slow is considered precise if the amount by which it is fast or slow remains constant. Such a deviation can be easily corrected. Consequently, the final test of accuracy takes place on your wrist. Your temperament or the nature of your physical activities can cause slight irregularities. Fluctuations in position, temperature, or air pressure, the presence of magnetic fields (as produced by most electronic devices, metal detectors, household appliances, etc.) as well as vibrations and other factors may also affect its accuracy. If you notice that your watch exhibits such irregularities, please do not hesitate to take it to an Authorized Patek Philippe Retailer or an Authorized Service Center where no effort will be spared to assure that it is adjusted to meet your expectations.

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.

SERVICE
We recommend that you have your watch serviced every eight to ten years. With this in mind, we suggest that you take or send your watch to an Authorized Patek Philippe Retailer or an Authorized Service Center. This gives you the assurance that your watch will be entrusted to the hands of a qualified Patek Philippe watchmaker in Geneva or at an Authorized Service Center.
The watchmaker will completely disassemble the movement and then inspect, clean, and lubricate all of 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 precisionadjusted for a further period of two weeks. 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 or need the address of your closest Authorized Patek Philippe Service Center, contact our International Customer Service Department in Geneva, or visit www.patek.com.
