SELF-WINDING

A NEW COMPLICATION IN A STEEL CASE
Patek Philippe introduces a new complication to its calendar watches: the weekly calendar, a semi-integrated mechanism displaying the current week number, in addition to the day and date. A particularly useful feature for the modern businessman.
This steel Calatrava Weekly Calendar also houses a completely new self-winding movement with optimized performance. The dial is notable for its exclusive letters and numerals which authentically reproduce handwritten characters.
