Patek Philippe 5178, Manual

The master watchmaker will completely disas-
semble the movement and then inspect, clean, 
and lubricate all the individual parts prior to reas-
sembly. All functions of the watch will also be 
tested in detail and the escapement regulated if 
necessary. Finally, its rate accuracy will be moni-
tored 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 retur-
ned 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 mainte-
nance of your watch, contact the Authorized Pa-
tek Philippe Retailer nearest to you or our Inter-
national 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 43 hours. If your watch 
stopped because you set it aside for an extended 
period of time, you can wind it manually with 
about 20 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.

CHANGING THE CASE BACK 

Your watch comes with a sapphire-crystal case back 
and a separate interchangeable solid metal back. 
Only qualified master watchmakers at the Patek 
Philippe workshops in Geneva are authorized to 
exchange the backs. 

PATEK PHILIPPE SEAL

The Patek Philippe Seal is a global emblem of qua-
lity 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 design-
related 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 ti-
mepiece.
