Patek Philippe

Dear Sir,

We thank you for your mail we received via our Website.

Kindly note hereafter our reply to your questions :

1. New Caliber 324

Kindly note that our Caliber 315 SC will progressively be replaced by the Caliber 324 SC AIG.S - an improved movement, and this is forseen as of April 2008.

It is possible that some 324 Calibers has already been mounted in some models. 
For the end user there is no difference in terms of accuracy and reliability between the Calibre 315 and the Cal. 324. The advantage of the Calibre 324 vs. the Cal. 315 is a gain in efficiency and time in terms of our watchmakers’ work as it is easier to time the calibre 324 to the Patek Philippe high precision standards.

For your information, only the referende 5127 willl remain equipped with the Caliber 315 for the time being. Patek Philippe does not divulge the information about quantities of Aquanaut delivered with cal. 315.

Sincerely yours,

NORTHERN EUROPE
